The fourth day of the fourth month of the year is April 4. In countries where it is customary to record the date starting with the month rather than the day (as is done in the United States of America), this day will be designated as 4/04. For the serial number of the day in the month, Americans put a zero before single-digit numbers so that there are no discrepancies. There cannot be a fourteenth month in a year, so there is no zero before the April serial number. Entry 4/04 was taken as the date of the unofficial holiday, Webmaster's Day. The fact is that when using a web application, you can quite often see an error with status code #404 (Not found). It means that the resource that the server is accessing is missing. From the point of view of a user who has not received the final product, this situation looks like another error and it is not important for him to know what its number is. But for the webmaster, status code #404 is informative and means the work was poorly done. That is why it is the fourth of April, and not the tenth. For a server that accesses the specified address and does not find the one it is looking for, various status codes are provided. If there is information that the requested page existed, but now it does not exist, error #410 (Moved, Gone) occurs. This may happen not through the fault of the site builder (webmaster), but for other reasons. In the early 1990s, a specialist who knew how to create and maintain websites in a viable state was, in the truest sense of the word, a multi-instrumentalist, a one-man orchestra. He mastered the techniques of competent design, content, programming, administration and technical support of the site. That is, all those tools that are now used by web designers, content managers, developers (aka programmers), system administrators and database administrators, as well as resource support specialists in working order. Such a universal professional could easily be called the master of the situation, which is what they began to do. Tim Berners-Lee, author of the “StyleGuide for online hypertext”, first introduced the term webmastering. This happened in 1992, at the dawn of the Internet. The word quickly came into use as being meaningful and reflecting the essence of the activity. Master (master) from English has several translations, among others - master, owner, owner. Accordingly, the owner of the position of a small part of the web (web in English is translated as “web”) was called the webmaster, without specifying the specification. Later, with the development of the World Wide Web, the advent of more complex technologies, larger sites, a division of labor was required to increase work efficiency. Separate areas of web mastering have emerged, the number of which is constantly growing. But the holiday is celebrated by everyone involved in the creation of Internet resources. Including web mistresses, that is, not masters, but mistresses of the position. Mistress is translated from English as the female equivalent of master.

On April 4, the Roman Catholic Church honors the memory of Saint Isidore of Seville, considered the patron saint of the Internet. This venerable husband deserved such an honorable position in the modern world because during his lifetime he was the smartest person and an extraordinary personality. He was declared the patron of the Internet in 2003 by Pope John Paul II himself. The birthplace of Isidore of Seville was New Carthage, around 560. The future scientist was born into a Christian family that had 3 more children. Isidora's brothers (Leander and Fulgentius), as well as his sister (Florentina) were also outstanding people, they were later canonized. Isidore of Seville is the author of numerous works in various disciplines. He was interested in grammar and natural science, history and theology, mathematics and rhetoric and many other sciences. What is his “Book of Canons” worth, in which all the resolutions of the councils that took place, starting from the era of earliest Christianity, were collected! His historical work “The History of the Goths, Vandals and Suevi” is also of the highest value. However, his most famous work, translated into 20 volumes (448 chapters), is “Etymology” - the world’s first encyclopedia. In a book whose main purpose was to explain the meanings of words and their origins, a lot of information is given along the way. They relate to history, law, cosmology, agronomy, zoology and other areas of science. Possessing broad views and reforming abilities, the Bishop of Seville also promoted the work of other scientists. He was among the first to introduce and promote the works of Aristotle in Spain. Along with the study of other subjects, Aristotle's philosophy was taught in diocesan schools in Spain precisely at the insistence of Saint Isidore. The spiritual deeds of the Bishop of Seville are also great. For 37 years he occupied the see of Seville, managing to convert many of his heretical compatriots to the “canonical faith.” And he himself did not give up ascetic deeds until his death (he lived for almost 80 years). At the end of his life, he distributed everything he had to people in need. Thanks to generously distributed alms, his house was filled day and night with poor people from all over the country. 17 years after the death of the holy enlightener, the eighth council of Tolero proclaims him as “an incomparable scientist, an adornment of the Universal Church, the most enlightened person of a bygone era, whose name should always be pronounced with respect.” Much later, the Catholic Church will choose Saint Isidore as the patron saint of the Internet, primarily for the same characteristics, which not only represent great value at all times, but also harmoniously complement today the World Wide Web - the treasury of practical and theoretical knowledge of mankind.

They are friendly, trusting, smart, cunning and clean. Due to the fact that they reproduce easily and are undemanding in care, they have become permanent inhabitants of laboratories. Rats help humans in many studies; our genomes coincide with them by 90-95%. That is why so many interventions in human physiology are carried out only after experiments on these rodents. And therefore the rat deserves its day in our human calendar. It is worth mentioning that we are talking about a domesticated, manual species. It is believed that the domestication and breeding of pet animals began in England. The animals are fundamentally no different from their wild relatives, but their level of aggression is significantly lower. At the same time, their learning abilities are much higher than those of many pets, such as cats. When choosing the date, the Internet resource ratlist played a key role; this is the oldest site dedicated to decorative rats. Ratlist, created to help lovers of decorative animals, has helped the owners of these rodents. Communities were formed there, hot issues were discussed, and animals were offered into good hands. In gratitude for the work, rat breeders and rat lovers set the founding date of the resource, April 4, as a celebration of World Rat Day. On this day, the animals probably feel the same festive excitement as their owners. During the holiday, it is customary to pamper your pets with delicious treats, give them new toys and even cards. Rodents happily treat themselves, play with new devices, and carefully... tear the postcards and place them in their nest corners with crushed pieces. Therefore, paper products related to World Rat Day should be produced using non-toxic dyes. The best gift for Rat Day is the rat itself. These animals are incredibly social and love company. If an animal lives alone in a cage, it develops worse and does not occupy itself to the fullest extent of which it is capable. Rodents that live in families are much happier. They look after each other, sleep curled up in a tight ball, play together, jokingly take each other's toys, and are able to express information in a unique language. If the rat is tired and wants a little personal space of its own, it can go into a corner at any time and sleep there. None of her relatives will pester her. But if she is bored, she will immediately find company. This is why it is so important to keep rodents in the company of their own kind. World Rat Day aims to convey such valuable information to all those who love these cute rodents. There are many lovers, some are so zealous that they express their feelings through unique slogans. “If you want to please me, try to please my pet rat first.” “My little rat is the only friend who will never leave me.” “It’s hard to be modest when a rat loves you.” The most touching and main motto of the holiday is the expression “For the whole world you are just one person, for a rat you are the whole world.”

At the initiative of the UN, since 2006, April 4 has been recognized as the International Day of Mine Awareness and Assistance in Mine Action. The emergence of such a day was facilitated by the initiative coming from the UN Secretary General. The underlying message behind the day's significance is that landmines are "invisible killers." Despite the fact that large-scale wars and conflicts affecting the interests of the world community have long since sunk into oblivion, they sometimes make themselves felt. Every year, about 15 thousand people die when they involuntarily set off mines left behind decades ago. As a rule, civilians who are not properly aware of such echoes of war die. In addition to other activities carried out by the United Nations, the existence of April 4th will be able to attract the necessary amount of attention not only to the problem of mine clearance, but also to the problem of the existence of landmines and their direct use. Unfortunately, not all mines set in motion are relics of past wars. Such weapons are actively used in third world countries and terrorist organizations. This is due to the fact that the latter do not have the proper military potential. And mines, due to their simplicity of design and ease of handling, have a low cost. Such a weapon can be in a state of waiting not only for months, but also for years. At the same time, without requiring care, maintenance and constant maintenance. Their use is not affected by the economic climate, as well as the armed training of other states. In other words: the mine lies and waits to be activated. The existence of this day is dedicated to this problem. Along with the proclamation of April 4, the UN General Assembly called on states and state-like entities not only to create, but also to develop national means to combat mine danger in those countries where remnants of war pose a direct threat to the life, health and safety of the population, as well as social and economic development of society. Despite the current age of high technology, mines have not gone into the shadows and remain a serious threat to civilians. Measures taken by the UN, including the establishment of the International Day, as well as the adoption of Conventions and programs, annually reduce the number of victims of mines.

Carrots were eaten and used for healing 2,000 years ago by the ancient Greeks and Romans. It was considered an exquisite treat, so it was served only on holidays. The vegetable was grown for its seeds and tops, rich in vitamin C. Later, they began to prepare dishes from the juicy root vegetable - a source of beta-carotene, fiber and carbohydrates. International Carrot Day is celebrated on April 4 every year since 2013. The main idea of ​​International Carrot Day is to spread information about the benefits of this vegetable for the human body. Initially, carrots were classified as wild plants, which were eventually domesticated, about 4,000 years ago. Swiss scientists found its fossilized seeds during excavations, the exhibits of which date back to the Bronze Age. Carrots appear as a favorite delicacy of gnomes in the ancient beliefs of Germanic tribes. Japan, China and India were the first to learn how to cultivate vegetables and develop new varieties. This happened in the 12th century. Afghanistan and Iran are considered the birthplace of white and purple carrots, and China is considered the birthplace of yellow carrots. The orange root vegetable familiar to us appeared in the 17th century. in Holland. In Russia, carrots began to be eaten in the 16th century. Vegetables of orange, red, yellow, white and other colors are used not only in cooking, but also in folk medicine, cosmetology and dietetics. Carrots are a source of vitamins A, B, C, E and K, microelements, flavonoids and essential oils. The nutritional value of the aromatic, tasty and juicy root vegetable is difficult to overestimate. This explains the vegetable’s demand for thousands of years. The root vegetable is eaten raw or after heat treatment, added to cold appetizers and main dishes, and used to make cakes, soufflés, candied fruits and other desserts. Carrot juice is consumed as a source of vitamins to strengthen hair and nails, to treat the pancreas, respiratory system and endocrine glands. Boiled root vegetables are included in dietary dishes that are eaten during peptic ulcers, diabetes mellitus, enterocolitis and enteritis. Heat-treated carrots contain more antioxidants than raw carrots, which allows them to effectively slow down the aging process of the body. For better absorption of fat-soluble vitamin A, both raw and cooked root vegetables should be eaten with sour cream or vegetable oil. Carrots lower blood cholesterol levels, strengthen the immune system and improve the functioning of the gastrointestinal tract. Regular consumption of vegetables reduces the risk of developing oncology (for example, lung cancer) and reduces by 40% the likelihood of night blindness in old age. Raw carrots eaten after meals prevent the development of caries, periodontal disease and other diseases. The root vegetable is a natural abrasive that helps clean teeth from food debris. Carrots, due to their beta-carotene content, help keep the skin healthy and clean, moisturize the upper layers of the dermis and make its color uniform. The vegetable also has excellent wound healing and antiseptic properties. Drinking carrot juice daily helps the body rid itself of stagnant bile, toxins and excess weight. It is recommended to include this healthy root vegetable in the diet of both adults and children. To saturate the body with important vitamins and microelements, you need to eat 100-200 grams of carrots per day. Scientists and doctors talk about this and much more on April 4 during the celebration of International Carrot Day. In honor of International Carrot Day, of course, people prepare various dishes, share their recipes on social networks, organize parties in carnival costumes with red parkas and other events.

There are special days throughout the year that encourage people to show compassion and take part in the lives of homeless animals. Pets end up on the street for various reasons, but they all suffer equally from malnutrition, cold, disease and aggression from the outside world. Every year on April 4, at the initiative of the Organization of Homeless and Stray Animals from the Netherlands, events and promotions are held that draw attention to the tragic fate of man's four-legged friends. There are about 600 million cats, dogs and other domesticated animals living outdoors in the world. World Stray Animals Day is intended to help them. The problem of protecting our little brothers began to attract attention only in the last 200 years of modern history. Both domestic and lost, those who have run away from their owners or thrown onto the street, mustachioed street children live from hand to mouth and often suffer from the cruelty of people. The first law protecting animals from aggression and violence was passed in 1822 in Great Britain. Its initiators were Member of Parliament Richard Martin and his ally Lord Chancellor Thomas Erskine. Later, similar laws began to be adopted in other countries of the world. In Australia, for example, it is prohibited to cut off dogs' ears and tails, use them to perform acts in the circus, or display kittens and puppies for sale in pet store windows. In addition to improving the situation of stray animals and protecting them from aggression, World Stray Animals Day encourages people to pay attention to their uncontrolled reproduction. On April 4, sterilization and castration of homeless four-legged animals is carried out. Animals are delivered to veterinary clinics by volunteers, who also raise funds to maintain shelters and find new owners for pets. Japan is known for its reverent attitude towards cats, which are a symbol of happiness and prosperity. However, it was in the Land of the Rising Sun, thanks to the ruler Tokugawa Tsunayoshi, that a shelter for dogs was opened in 1695, in which there were about 50 thousand animals. His decree “On the prohibition of depriving living beings of life” also remained in history. The initiative of the “dog shogun” did not find understanding among his subjects. However, during the life of the emperor, cruel treatment of four-legged friends was followed by severe punishment, including the death penalty. In the USA, in the state of Pennsylvania, the first shelter for stray animals was opened in 1869. In Europe, a little later - in 1885. In addition to municipal ones, private shelters appeared in Ireland, England and other countries. They existed due to charity - voluntary donations from citizens. The first shelter for stray dogs in the Russian Empire was organized by Emperor Paul I at the end of the 18th century. on the territory of the Mikhailovsky Castle. The Russian Federation joined the international practice of protecting the rights of homeless animals in 1990. This year, the first shelter was opened in the Moscow region, and by 2021 there were more than 150 similar establishments in the country. World Stray Animals Day calls on people to pay attention to their tragic fate and alleviate the situation of pets who, by the will of fate, find themselves on the street. On April 4, educational, charitable and other events are held aimed at helping homeless four-legged animals. World Stray Animals Day reminds us that humane treatment of living beings is a hallmark of Homo sapiens and is an important component of morality and ethics.

Musical instruments require regular maintenance and tuning according to the system of pitch-to-sound ratios. This is done by masters with appropriate education. People who have an ear for music are responsible for calibrating the sound of grand pianos and upright pianos - the ability to distinguish sounds in the range of 20 Hz-20 kHz. A holiday has been established in honor of professionals who are involved in the maintenance of instruments from the keyboard-string family. April 4th is International Piano Tuners Day. The regularity of piano and grand piano maintenance depends on the playing load. Tuning is required once every six months if the tool is hardly used. With medium to high gaming loads, service intervals are reduced. If the piano is out of tune, but the performer plays it, he will develop an incorrect ear for music. This reflects poorly on his creativity and, subsequently, on his professional career. In addition to the quality of performing skills, the work of the tuner is the key to the correct transmission of sounds in height and frequency, i.e. the way Schubert, Shostakovich, Tchaikovsky, Beethoven, Strauss and other musical authors intended it. Due to the advent of electronic synthesizers, the demand for masters who perform mechanical adjustments of grand pianos and upright pianos is declining. However, traditional instruments, and the acoustic piano in particular, are still used to accompany performers of modern songs and classical arias or to play in an orchestra. Only on pianos and grand pianos with hammer action can the sound of the classics be achieved in all its pristine beauty. Therefore, piano tuners are regularly invited to tune up pianos or grand pianos at home, in music schools and concert halls. The frequency of the instrument's sound is affected not only by the quality of service, but also by the surrounding environment. Shock during transportation, dust in the air, high temperature and humidity make adjustments to the piano's performance. Therefore, tuners draw the attention of owners to maintaining the correct conditions for maintaining the piano or grand piano. This allows you to increase the service life of the tool by 3 times. To celebrate International Piano Tuner Day, exhibitions of classical and electronic instruments are held. In honor of the professionals, musical concerts are organized and programs are filmed in which they talk about their activities and share the secrets of their craft. These and other events help increase the prestige of the adjuster’s work. The holiday helps musicians express gratitude to the people without whom the performer’s work could not become filigree, and draw attention to the work of true masters of their craft.

Human health depends on the ecology of the place of residence, regular physical activity, proper and balanced nutrition. Vitamins, minerals and trace elements must be supplied to the body with food or in the form of dietary supplements. A person can produce some substances for normal functioning on his own. Thus, bifidobacteria found in the gastrointestinal tract and respiratory tract synthesize vitamin K, promote the absorption of vitamin D, and quite actively produce B vitamins. The body cannot produce some low-molecular organic compounds on its own. These include vitamin C. Ascorbic acid is a powerful antioxidant that stops the accumulation of free radicals. It strengthens the immune system, supports the functioning of the central nervous system and helps fight stress, because. found in the adrenal glands, which are involved in the production of the hormone cortisol. Biochemist Charles King's isolation of pure vitamin C from lemon juice in the laboratory was an important event in human history. The registration of an organic compound with the formula C6H8O6 took place on April 4, 1932. In honor of the scientific discovery, a holiday was established - Vitamin C Day. Scientists discovered ascorbic acid (that is, acting against scurvy - “scurvy” in Greek) in food products in 1912. The colorless, light and water-soluble element is found in large quantities in citrus fruits, berries and vegetables. Most animals and plants can produce vitamin C on their own. Humans and other primates lost this ability during evolution. Ascorbic acid is involved in the growth and restoration of gum cells, bones and teeth, blood vessels, participates in the breakdown of fats, and promotes the absorption of iron by the body. The lack of vitamin C led to mass deaths from scurvy among the crews of Vasco da Gama's team and other travelers of the era of great discoveries. Therefore, Peter I, when creating the Russian fleet, ordered the introduction of oranges and lemons, delivered from the south of Europe, into the diet of sailors. The synthesis of ascorbic acid in 1933 by scientists Howard and Reinstein was a real breakthrough in the development of science, which helped cope with scurvy, a disease that claimed millions of lives. In 1928, Albert Szent-Gyorgyi, a biochemist of Hungarian origin from the United States, discovered a seemingly incredible connection between the appearance of dark circles around the eyes, hyperpigmentation of the skin of patients suffering from adrenal insufficiency and Adison's disease, and the darkening of fresh cuts of potatoes, pears and apples. While citrus fruits did not darken, i.e. There was no oxidation process in the pulp upon contact with air. From red bell peppers, oranges, lemons and from the adrenal cortex, A. Szent-Gyorgyi isolated an antioxidant, which he called hexuronic acid, later renamed ascorbic acid. In 1937, the scientist received the Nobel Prize for the discovery of this “substance of life.” But the first step in this direction was taken in 1932 by C. King. Therefore, every year on April 4, Vitamin C Day is celebrated around the world.

International holidays - Internet Day

Exactly 106 days after the winter solstice, Qing Ming is celebrated, a holiday reminiscent of All Souls' Day. Most often the date falls at the beginning of April. Usually on the eve or after the fifth day of that month. According to the agricultural calendar, Qingming is one of the 24 seasons, which signals the arrival of bright and pleasant days. It is not without reason that it is called the day of purity and clarity. It is with the onset of this season that coincides with the beginning of warm weather, lighter winds, which are beneficial for agriculture. Nowadays, the Qing Ming holiday is an opportunity to visit family and relatives, as well as the graves of loved ones. According to beliefs, the souls of the dead wander the world and have the same needs as the living, they feel cold, hunger and thirst that must be satisfied. On this day, the whole family gathers at the cemetery, and the eldest member of the family places a ritual bowl of food on the grave for the deceased. There is a tradition of burning ritual money and other requisites, which, according to tradition, are thus transferred to the deceased. Such rituals are now most often held outside the cemetery. In addition to special money, also called hellish currency, cardboard models of beautiful houses, luxury cars, branded smartphones, and sometimes figurines of “prostitutes” are burned. Judging by the number of zeros on the hellish currency, the needs of the deceased are many times higher than those of the living. All family members, from the oldest to the youngest, pay tribute to the deceased by bowing to the ground three times. Symbolic sacrifices are also made to deities and wandering unknown souls. People believe that fed souls do not haunt the living, but help them. The Qing Ming Festival is a tribute and remembrance for people who are not around. Also, according to beliefs, an angry soul can greatly harm its relatives. That is why, in order not to test the patience of the ancestors, such interesting and unusual rituals are performed.

Funny holidays - Jeep 4x4 Day

April 4 (March 22, old style) according to the folk calendar, Vasily Kapelnik is celebrated; Vasily was also called Solnechnik, Greenhouse or Teply. The holiday itself was named in memory of the holy martyr - Basil of Ancyra, revered on this day by Christian believers. Basil served as presbyter in Ankyria in the 3rd century. When the Aryan heresy began to spread, the presbyter was denounced and defrocked. He courageously encouraged his flock to be faithful to the Orthodox faith. Then the saint was recognized as dangerous for the state and was forced to renounce Orthodoxy. However, he glorified God and was subjected to terrible torture, the skin was cut off from his body and burned with red-hot rods, as a result of which the martyr died. Among the people, on Vasily’s day the sun became hotter, the remnants of snow dripped from the roofs, and the air became very warm. That is why they nicknamed Vasily according to the spring weather. But the warm weather did not make the roads any drier. Melt water flowed in streams along the slopes to the reservoirs. If the peasants intended to build a new house, it was on the day of Vasily Kapelnik that they looked after the flowing streams. The most watery places were avoided for the construction of housing, otherwise the building could soon wear out. But elevated areas were valued. The housewives of Vasily Kapelnik baked bread cakes, symbolizing the sun, and treated their households to them in the morning. Such a loaf was revered by the people, believing that it brought wealth and prosperity to the family. The dough was usually kneaded from rye flour, since poor people could not afford unnecessary waste. And wealthy families bought wheat flour for the loaf. According to folk signs, on the day of Vasily Kapelnik, the future was determined. The red rays of the sun at dawn foreshadowed an excellent harvest. Dark blue clouds were observed before warm, rainy days. If snow melting began from the northern part of the anthill, the flying season was expected to be long and fine.

Orthodox holidays on April 4:

Feast of the Icon of the Mother of God “Izborskaya”

Memorial Day of Hieromartyr Vasily of Ankyra

On April 4, June 12 and August 16 (new style), the Orthodox Church celebrates the Day of Remembrance of St. Isaac of Dalmatia, who served as abbot in the 4th century. According to historians, Isaac was born in Syria and from his youth chose the monastic path. He went into the desert and prayed to the Lord alone. But one day he heard a voice from above to go to Constantinople. In the city, Isaac learned about the persecution of Orthodox believers, during which adherents of the Aryan heresy destroyed and closed Orthodox churches. At that time, the barbarian Goths attacked the empire, and Emperor Valens went with an army to meet the enemy to defend the state. Then Isaac appeared to Valens and asked to open Orthodox churches and stop the persecution, for this the Almighty would help him win. But Valens did not listen to the monk and, after the third time of persuasion, he ordered Isaac to be beaten and then thrown into a swampy pit with thorns, from which not a single mortal could escape. However, the angels of the Lord helped the monk get out of the deadly ravine. Appearing to the emperor for the last time, Isaac warned of a prophecy that if he did not leave the Orthodox believers alone, he would be defeated in his battle, and the emperor himself would die a fiery death. Seeing the surviving monk, Valens ordered him to be locked in prison until he returned from the battle. But the monastic prophecy was fulfilled - the battle was lost, and the ruler, hiding from the enemy, burned alive in a wooden building. Theodosius I the Great ascended the throne, he released the monk-prophet and, on his instructions, rid Constantinople of the Arians and began the restoration of churches. The monk was already thinking of returning back to the desert area, but the emperor’s close associates Victor and Saturninus begged the elder to stay and pray for the fate of Constantinople. Then he asked to build him a small cell outside the city. The new ruler revered the wise old man and often met with him in his palace. The monk also visited the houses of the townspeople, prayed for them, helped the poor, and gave all his alms to the needy. Other monks were drawn to him, and a monastery was built around the monastery, where Isaac himself was the abbot. Before his death (383), the elder called his disciples and gave instructions to everyone. He appointed the pious Dalmatian as his deputy, from whom the Dalmatian monastery was named. And Isaac himself was eventually nicknamed the Dalmatian.
