In mid-spring, the inhabitants of planet Earth celebrate the International Day of Environmental Awareness. The importance of the idea was first thought about in 1992 in Rio de Janeiro, when the UN Conference was held in this Brazilian city. Since then, the environmental celebration, which falls on April 15, has been considered an important “green” date on the calendar. Celebrated in the Russian Federation since 1996. The approval of this date is very important for the entire society, because the environment is in great need of universal support and protection from the harmful influence of the anthropogenic factor. Protecting Mother Nature and preserving it for future residents are the main steps that lead to sustainable and safe development. In order for people to understand the value of an idea, it is necessary to carry out educational work and instill proper, non-consumer thinking from a young age. The public must be informed about the state of the environment and planned and implemented steps in the field of environmental safety. The festival aims to eradicate the consumerism and thoughtless attitude of people towards natural resources and the environment, and environmental education should raise awareness among people and also direct their thought process in the right direction. On this day, all sorts of events are organized: exhibitions, conferences, round tables, seminars, etc. In educational institutions there are speakers who focus on topics such as the protection of animals and plants, as well as natural resources. Interesting master classes are organized for the youngest participants in the celebration (planting trees, creating birdhouses, cleaning up the area, etc.). All environmental events are necessarily covered by media workers in order to attract more ordinary citizens to participate in actions to improve and revive nature. A person of any age can become part of an environmental project or a general “green” action, and thereby contribute to solving the problems of a general environmental crisis in a local area. Preserving the unity of man with Mother Nature is very important, both for the current inhabitants of the Earth and for descendants. Solving the necessary problems is possible only through joint actions aimed at improving people's awareness of this serious issue.

The main difference between modern people and their ancestors is their higher degree of development. But it is a mistake to believe that a person who lived long before we were born had completely wild ideas about certain things. For example, in Ancient Egypt and Ancient Greece the development of culture was already observed. And currently, much effort is being made to preserve traditions and values ​​that are significant to the world community. One of the clearest examples of this is the regular celebration of International Culture Day on April 15. The date was established in 1998 on the initiative of members of the World League for Cultural Preservation, founded in 1996. For the first time, the idea of ​​establishing this holiday was proposed by Nicholas Roerich. This event took place in 1931 in Belgium at a congress dedicated to the promotion of an interethnic pact for the protection of culture. At the conference, the key goal of the solemn date was announced - propaganda calling for the knowledge of all that is beautiful. In the spring of four years later, at the Roosevelt residence, the international agreement “Roerich Pact” on the protection of cultural property was adopted. Nicholas Roerich himself always called culture the only effective tool for the improvement of humanity, seeing in it the basis for the unification of all people, regardless of religion and affiliation with any one. or nation. The decision to establish official protection of culture came to him in the first half of the last century, during the study of ancient Russian monuments. The Russian-Japanese military conflict, which occurred in 1904, forced the painter to seriously worry about the safety of cultural property. In 1914, he approached Russian officials and the governments of the remaining warring states with the idea of ​​​​ensuring the protection of ancient monuments through the conclusion of an appropriate treaty. However, the call was ignored. After 15 years, the artist drew up and published a draft agreement, supplementing it with a message to the residents of all countries. This document caused a wide resonance and found a response among the world community. Committees have been formed in individual states that strongly support the project. As a result, the Pact was approved. Every year on April 15, many countries around the world celebrate this holiday. The list of events organized on this day all over the world, in particular in Russia, officially recognized as one of the most cultural states on Earth, is as diverse as the concept of culture itself. The program includes: - exhibitions dedicated to the culture of various nationalities; - scientific congresses dedicated to this topic; - educational lectures on the culture of different nations; - festive concerts; - evenings of poetry and classical music; - performances and stage performances. An obligatory attribute of the event is the ceremonial raising of the Banner created by Roerich - a white canvas depicting three circles (symbols of the past, present and future).

The date of the professional holiday of electronic warfare (EW) specialists is associated with a real historical event. On April 15, 1904, Japanese ships attempted a lob attack on the fortifications and roadstead of Port Arthur. One of the enemy ships was adjusting their fire via wireless telegraph. Telegraph operators from the station on Zolotaya Gora and the battleship Pobeda, having assumed such a development of events, began to interrupt the enemy message with a large spark. Such a signal has great power and is able to suppress the enemy’s frequency. The idea of ​​the Russian sailors was crowned with success - the shooting of the Japanese ships was ineffective. The actions of military telegraph operators confirmed the developments of Alexander Popov, who in 1903 proposed methods for conducting radio reconnaissance and jamming. This forced the military command to take a different look at the capabilities of wireless telegraphy. The tasks of intercepting call signs and then using them for one’s own purposes and jamming enemy transmissions were simplified due to the technical imperfections of the equipment of that time. The same principle of operation and construction of the transmitters (sometimes components from the same company) made it possible to operate with a large spark. Modern electronic warfare systems have changed dramatically, new functions and capabilities have appeared. Despite the technical superiority of today's technology, it solves almost the same problems as it did a hundred years ago. In the context of the constant technical development of all means of defense and attack, electronic warfare is faced with strategically important tasks for the country. Using our equipment, our specialists are capable of:• collecting and storing military information, including target designations;• transmitting information to space objects;• using homing objects with increased guidance accuracy;• accurately hitting pre-selected targets;• creating active and passive interference and much more. Effective electronic warfare against the enemy is impossible without modern technical means and highly qualified specialists. Electronic warfare personnel are constantly improving their skills in the use of standard electronic countermeasures. The number of trainings and exercises exceeds one hundred per year. Exercises are being conducted for units directly aimed at performing main tasks. Electronic intelligence specialists take part in all major army and navy exercises, ensuring the tasks assigned by the command. The “Krasukha-4S”, “Murmansk”, “Moskva” complexes have shown their high efficiency not only in covering friendly units, but also in quickly suppressing SUVs of a mock enemy. The developments of our specialists make it possible to disrupt the operation of control systems at a distance of up to 5000 km. “Murmansk-BN” suppresses up to 20 targets simultaneously at this distance. The modern history of the holiday began in 2006 with the signing of the corresponding Decree by the President of the Russian Federation. Our country's leadership in electronic warfare is recognized by foreign military experts. The exploits and merits of electronic warfare specialists are not noticeable, but this does not make them less significant. Happy holiday to all military personnel and veterans!

The Chernobyl accident, the depletion of natural resources, and the sharp deterioration of the environment led to the establishment of a solemn day dedicated to environmental protection. The decision was made by the Government of the Russian Federation on June 11, 1996. The initiators of environmental events were public organizations and the Ministry of Nature. The Russian experience of attracting the attention of the state and the public to the problem of protecting nature from the negative influence of humans has been adopted by the Czech Republic, China and other countries. Promotions, lectures, seminars, round tables and exhibitions are held from April 15 to June 5 under the motto “Ecology - Safety - Life”. During this period there are many holidays of a similar focus: Earth Day, International Climate Day, March of Parks, International Day of Remembrance of the Chernobyl Disaster, Environmental Education Day, etc. Each of them, to one degree or another, at the regional or global level, addresses the problem of wildlife pollution as a result of human activity. Active participants in the Days of Protection from Environmental Hazards, starting on April 15, are nature reserves, national parks, environmental societies, foundations, museums, libraries and educational organizations. Over the 20 years of existence of the holiday, traditions have formed - conferences, lectures and competitions dedicated to the state of the environment are held by professionals and simply caring people. The initiators of Protection Days attract school and university students to participate in them, thus contributing to the formation of healthy thinking and a responsible attitude towards nature among the younger generation. In honor of the holiday, cleanup days are organized in many regions of the Russian Federation, during which not only local areas and city streets, but also public gardens, parks, forests and reservoirs are cleared of garbage. Some events to protect nature are held online. Thus, everyone is invited to take a virtual tour of environmental education centers and take part in surveys and competitions held on the Internet. Such events give a new impetus to the formation in the minds of people of a responsible attitude towards living and inanimate nature. The streets of populated areas become the venue for flash mobs and events, and for the distribution of environmentally themed literature. The joint efforts of professionals, the public and government agencies help to achieve solutions to environmental pollution problems, both at the level of individual regions and throughout the world. Days of protection from environmental hazards encourage people to live in love and harmony with nature, part of which is the “crown of creation” - man.

World Art Day has been celebrated annually since 2012. In honor of this holiday, exhibitions of paintings, prints and sculptures are held, open days are announced in museums and galleries. The date of the celebration is April 15 - the birthday of the artist Leonardo Da Vinci. Fine art is one of the important components of culture. In 1929, Nicholas Roerich addressed the peoples and governments of all countries of the world with the initiative to conclude a Pact on the protection of historical monuments, artistic and scientific institutions. The philosopher and artist proposed concluding a Treaty on the Protection of Treasures of World Culture, which was especially relevant in light of the events of the First World War. This Pact was solemnly signed in Washington on April 15, 1935. In honor of this event, the International Day of Culture is celebrated annually. Both complementary holidays fall on April 15th. The great figure of the Renaissance was born in Italy in April 1452. Leonardo received his first lessons in painting and sculpture in the workshop of the famous sculptor and artist Andrea del Verrocchio, who worked in Florence. There, Da Vinci mastered the basics of working with plaster and metal, and studied the basics of mathematics and mechanics. All this knowledge in the future was useful to the future artist, whose genius manifested itself in various areas of human activity. 1. In 1482-1499. Leonardo served as an engineer at the court of the Duke of Milan, Ludovico Sforza, where he designed various military technical devices - for example, a spike lock for a pistol. At the same time, the artist created 2 brilliant works - the fresco “The Last Supper” and the painting “Lady with an Ermine”. 2. In 1490-1492. Da Vinci studies anatomy. The result of his inquisitive mind is the “Vitruvian Man” - a drawing of a naked man in which the canonical proportions of the body are observed. The artist coins the term "golden ratio". 3. In 1503-1519. Da Vinci, living at the court of Francis I, King of France, creates a mechanical lion. Thanks to the internal engine, the king of beasts, made of metal and wood, could not only move. When his chest was opened, a bouquet of lilies became visible - the heraldic symbol of the kings of France. And although Da Vinci’s main work is rightfully considered “La Gioconda,” we should not forget that he was responsible for the design of a hang glider, a submarine and other inventions unimaginable for the inhabitants of the Renaissance. These include a gateway with sliding doors for the water utility, a searchlight, a portable pianola, a prototype of a modern helicopter, a crossbow, a parachute and an anemometer - a device for measuring wind speed. It is no coincidence that Leonardo Da Vinci became a symbol of peace, freedom of artistic thought and self-expression. His life is a clear illustration of the famous expression of L. Feuchtwanger: “A talented man, talented in all areas.” Therefore, it is entirely justified to celebrate World Art Day on April 15, when a brilliant artist, sculptor and inventor was born in a village near the city of Vinci.

It is impossible to imagine the life of a modern person without mobile communications. Sometimes your whole life is concentrated on your phone: communication with friends, family and colleagues, news of the day, hobbies, entertainment. A variety of applications allow you to make purchases, meet new people, listen to your favorite music, and watch movies without leaving your home. Often, it seems that the irreplaceable mobile connection enslaves people. In 2008, a new term “nomophobia” (“no-mobile-phone phobia”) appeared - the fear of being left without mobile communications or a telephone. Many people feel helpless and alone, having lost their means of communication even for a short time. Psychologists around the world are sounding the alarm about the emergence of a new addiction - from mobile communications. Its influence on a person’s personality is as serious as the influence of drug addiction, gambling addiction, and alcoholism. Correspondence communication with a large circle of people saves introverted people from loneliness and allows them to compensate for the lack of communication in real life. Mobile addiction has created a need to have at least one day a year without communication. World Mobile Free Day invites you to give up your mobile phone for a day in order to understand the importance of its presence in our lives. On this day, a person is left alone with himself, rethinking life, thinking about how far progress has come, how important live communication is. At World Mobile Free Day, people all over the world raise the issue of the impact of mobile communications on the environment and ecology. Some go on strikes and rallies against increasing communication fees, putting forward demands for cellular operators to use special equipment that reduces radiation into the environment, and increase the environmental friendliness of production. The invention of the 20th century gave society a lot of positive aspects. With the help of mobile communications, it is possible to save hundreds of human lives and prevent disasters by promptly transmitting information to rescue services about accidents, accidents, and sudden deterioration in health. With the advent of this type of communication, people have the opportunity to communicate more, despite vast distances, receive unlimited amounts of information, develop, and master new professions and practices. April 15th is a day of voluntary refusal of mobile phones, designed to make people feel the importance of the invention of wireless communication for people's communication.

April 15 is an alternative to February's Valentine's Day, but with bright notes of the originality inherent in the Kazakh people. The holiday was initiated by the youth part of the Bolashak movement in 2011, who held large-scale protests against the celebration of the traditional international holiday. It was considered propaganda of licentiousness, and, moreover, completely inconsistent with the religious beliefs of the country. The new date is associated with the folk epic of the 13th-14th centuries, promoting the purity and beauty of true love. It is based on the legend about the young man Kozy and the girl Bayan. Engaged in early childhood, the lovers saw their lives only with each other. But they could not resist the cruelty of circumstances: the girl had to be given by force to marry another man, Kodar, who seemed to Bayan’s father to be a more promising groom. Kodar villainously killed the Goat, thinking that this would force the rebellious one to belong only to him. Then Bayan, using her cunning, forced Kodar to go down into a deep well, holding on to her braids. When Kodar did this, she cut off her long hair and threw stones at the well. Having avenged her lover, Bayan committed suicide. Kozy and Bayan were able to reunite after death - they were buried together. The light of love left by the hearts of the horseman Koza and the beautiful Bayan has inspired playwrights, ethnographers, poets and historians not only of Kazakhstan, but also of other nations for centuries. In order for the new holiday to take root among young people and become a full-fledged replacement for the traditional one, activists and the government are trying to make the program of events as rich as possible. The celebration scenario necessarily includes a competition for young couples, a dance tournament, and the reading of love poems. Schools organize themed evenings, all kinds of games and competitions, for example for the best wall newspaper dedicated to the celebration. Young people organize flash mobs - launching paper Chinese lanterns into the sky.

In Georgia, the holiday of love is celebrated twice: the first on February 14, the next on April 15. Moreover, the last date even has official status. In general, the residents of this sunny state are accustomed to showing love and respect for each other, regardless of the holidays. However, when there is a real reason, the event is celebrated with great pleasure. The main initiator of the establishment of this date was the famous Georgian showman Besiki Chubinidze. Local officials really liked the artist’s idea and, by the end of the last century, deputies proclaimed April 15 as the Day of Love. At first, the holiday was established as an alternative to the Western Valentine's Day, but everything turned out differently. Couples in love celebrated the new holiday with enthusiasm, but did not forget about February 14th. Despite its official status, Love Day is a working day, unless, taking into account the year, it falls on a weekend. Human psychology is considered the most ambiguous, but the role of love in the fate of people is defined as the main one. Although our life can sometimes be very difficult, this bright feeling always occupies a key place in it. A woman and a man are two opposite poles, in dire need of each other. Perhaps they themselves are not aware of it, but they feel a mutual need. No matter how banal it may sound, time has no power over real feelings. Falling in love disappears, passion subsides, affection fades, but true love remains for a long time. She does not allow this entire kaleidoscope of emotions to go out, forcing it to flare up again and again with renewed vigor, uniting souls, destinies and thoughts. Love can be very different. This feeling manifests itself in relation to the mother, child, friends and loved ones. Being attracted to someone dear to your heart with whom you communicate regularly is important. Imagine for a moment that every day you accumulate resentment and ill will towards your spouse, because you are not satisfied with some traits of his character. Then the answer to the eternal question of what love is for is imposed by itself. It helps us turn a blind eye to our partner’s minor shortcomings, look at them with understanding, accept them for who they are, let go of grievances and continue to live, respecting each other. It is difficult to imagine how many poems, poems, songs, novels, paintings and musical works were created thanks to this tender feeling. It helps people to realize themselves, become better, and work on their own knowledge and experience. When there is a person in your life who is always ready to support and listen, who trusts you with all his soul, you will certainly find a way out of any, even the most difficult, situation. Love inspires, sometimes pushing you to rash and bold actions. World-famous painters, writers, poets and composers raised this feeling to the level of a powerful force influencing the course of world history. For many years, it can become the only meaning in life, pushing aside all other worries and matters. According to Georgian traditions, on this holiday people give each other gifts, making pleasant surprises. Some even dare to talk about their feelings. It is worth noting that it is on April 15 that men most often call their lovers to the registry office. This holiday is especially popular among sellers of sweets and flowers, because on the eve of the event such goods are in great demand. On April 15, significantly more fresh bouquets and souvenirs are sold in the country than on everyday days.

Titus Icebreaker is popularly celebrated on April 15 (April 2 according to the old calendar style). On this date, Orthodox believers honor the memory of Saint Titus the Wonderworker, who lived in the 9th century in the territory of Asia Minor (modern Turkey). Thanks to him, the holiday was named. Titus aspired to become a monk from his youth. He went to the Studite monastery and took monastic vows. Titus stood out among other monks for his humility, persistent work ethic and great virtue. He was appointed a priest, and the Lord rewarded the monk with the gift of miracles. The saint became famous for his active defense of icons from iconoclasts and, by the will of God, lived to an old age. The people called the day of Titus Icebreaker, since the rivers finally opened up from ice. Residents did not miss the opportunity to tell fortunes on the ice: if a cracked ice floe went under the water, then a difficult year was expected; if it floated on top, it was the opposite. They were happy if there was more water after the ice broke, because its spill foreshadowed an abundance of herbs harvested for the winter for livestock. Often, on Titus Icebreaker, flocks of crows gathered near houses. To prevent them from causing trouble or hunger, they were driven from the rooftops. And not without reason, since supplies in cellars and barns were practically running out. The owners checked the remaining grain, began to save on baking bread, and the grain stored for sowing was forbidden to touch. Therefore, the date had a second name - Breadless Day. It was bad if the snow melted above the cellar first. This meant that wet grain was poured into the cellar in the fall and by spring it began to rot, releasing heat. But the peasants knew how to use it in practice. Beer or kvass was brewed from sprouted grain (malt). Titov's day was also called Barysh-day. It was a holiday of traders and resellers. In order for transactions to be successful, they spent the day in merry festivities. It was believed that a loud celebration would lead to great income. The signs on Titus Icebreaker were used to judge the upcoming weather. The cooing of doves predicted the coming warming. Seeing black grouse going deep into the forest to spend the night meant the approach of rain and winds. The singing of the dergacha (crake) foreshadowed a fruitful summer. A flock of cranes was observed flying south due to a bad harvest.

The holiday, celebrated annually, coincides with the day of the government decree of 1919, when the criminal investigation officially appeared. Its development as a separate part of the law enforcement system began in the 19th century, after the annexation of Ukraine to Tsarist Russia. The turning point was the 1860-1870s, when the tsarist police system was modified, because before that all the work of identifying, searching and capturing criminals was carried out by the general police. In 1873, for the first time on the territory of Ukraine, in Kyiv, an experimental detective unit began its work. It became the second to appear in the empire after a similar one organized in St. Petersburg. Having existed for a year, the Ukrainian investigation showed excellent results, and even the cessation of funding from the Kyiv local authorities could not detract from its merits to the higher management. In 1880, with the assistance of the governor, a full-fledged part of 17 employees was created. Even then, the foundations of functionality were laid that are still relevant today: detention, search for criminals, surveillance and tracking, registry. History made its own adjustments: the years after the revolution brought civil war to Ukraine in an attempt to gain independence in 1917-1918, and the detective units of the tsarist police ceased to exist. Only with the advent of Soviet power and the formation of the Ukrainian SSR in 1919, the formation of detective units began anew. Their existence and legal basis were recorded on April 15, 1919 by the Council of People's Commissars of Ukraine with a special Decree “On the organization of judicial and criminal investigation.” In 1920, the Central Directorate of Criminal Investigation was created, which is part of the Main Militia of the Ukrainian SSR. Over the decades, the structure of the criminal investigation department and the model of vertical subordination have undergone transformation. Since 2001, the official name is the Criminal Investigation Department, which is part of the Ministry of Internal Affairs of Ukraine. But the main tasks and goals remained unchanged: adequate counteraction to criminal offenses and the search for criminals. A professional holiday was organized for all employees, in which employees of related services, veterans, future employees - cadets of specialized specialties and their teachers also took part. On this day, in addition to congratulations from the command and senior management, concerts and entertainment programs are held for them and their loved ones. The presentation of certificates of honor and awards is mandatory; the awarding of extraordinary titles and the awarding of personalized weapons to the best criminal investigation officers is considered especially honorable. A special date, the 90th anniversary of the Criminal Investigation of Ukraine, was marked by the release of a special gift book edition dedicated to the history of the Ukrainian investigation and the installation of a monument near the building of the Kyiv Ministry of Internal Affairs. The famous detectives, Gleb Zheglov and Volodya Sharapov, like no one else, symbolize this holiday for people who strengthen law and order.
