Peter I issued a decree “On monitoring cleanliness in Moscow and on punishment for throwing litter and any droppings onto the streets and alleys” on April 9, 1699. Failure to comply with the will of the sovereign was punishable by whipping and a large fine. To clean up garbage on the streets, service people were hired, who also had to “take care of all yard work, repairs and other matters.” And although janitors in Russia first began performing their duties in 1649 under Tsar Alexei Mikhailovich, the emergence of the profession is associated with the issuance of a decree by Peter I. That is why the Day of Cleaning Industry Workers falls on April 9. The holiday is not official, but is solemnly celebrated by specialists who professionally clean apartments, houses, offices, restaurants, hotels, administrative buildings and industrial buildings. Cleaners not only clean the premises, but also provide laundry and dry cleaning services for furniture, wash windows, shop windows and house facades, and remove street trash. Professionals use highly effective products, special equipment and inventory, so the result of their work is incomparable to the work of a full-time cleaner or janitor. The owner of an office and commercial premises in which repairs or construction work has been completed, apartments and houses after a fire or flood cannot do without cleaning services. Our specialists have the skills to remove dirt from the surfaces of not only residential and commercial premises, but also the interiors of cars, boats and racing yachts. Company employees provide services to restore order and eliminate unwanted odors and mold in the form of disinfection of premises using UV lamps and industrial ozonizers. Therefore, cleaners are often invited to clean shower rooms, locker rooms, steam rooms and other rooms in baths, saunas and swimming pools. Industry workers are not only high-level professionals, but also financially responsible individuals. Clients of companies trust their property to specialists, without doubting its safety and the fact that they will not spoil rare items, antique furniture and expensive interior items. Calling cleaners in a timely manner is a justified financial investment for a business owner. Caring for furniture, office equipment and carpeting in the office significantly increases their service life. Regardless of the type of cleaning (maintenance or general), its regularity (daily or weekly) and other parameters, the premises are accepted by the customer in perfect condition after the provision of services. This also applies to the facades of houses, which professionals clean from efflorescence, soot, moss, mold, smog and other contaminants using industrial mountaineering. In this sense, the cleaning profession is not only responsible, but also partly unsafe. The holiday established in honor of specialists is an opportunity to pay tribute to their dedicated and important work. Therefore, in Russia, April 9 is widely celebrated as the Day of Cleaning Industry Workers.

It is not known exactly who made the decision to celebrate the birthday of laughing gas on April 9. Perhaps the author of this unusual holiday belongs to a dentist or other doctor, or maybe just a joker. It is not widely known; only people involved in medicine know about the date. Therefore, there are no established celebration traditions. What you definitely won’t be able to do on this day is without having to experience the effects of laughing gas. It is used only in medical institutions and under the strict supervision of specialists. But everyone who wants to celebrate the date can make a preventive visit to the dentist; it certainly won’t be unnecessary. Laughing gas is called nitrous oxide (nitrous oxide). This is an inert gaseous substance with a specific effect. It is colorless and odorless. When inhaled, it causes some intoxication, fun, euphoria, an excited state, and eliminates anxiety. In large quantities it acts like a drug. It has anesthetic properties, due to which it is used in surgery and dentistry - those who inhale nitrogen dioxide lose sensitivity to the effects of instruments. The use of nitrous oxide as an anesthetic has been known since 1799. The intoxicating and analgesic effect of this substance was confirmed by a number of experiments by research chemist Humphry Davy. And his experiments were based on the developments of the English physicist and priest Joseph Priestley. It was Humphry Davy who realized the promise of an inert substance for medicine and the possibility of using it to make procedures easier for patients. The problem was only the effect of over-stimulation. The researcher conducted experiments to determine the optimal dosage of laughing gas on himself. It turned out that the correct concentration of nitric oxide mixed with oxygen provides anesthesia without stimulating the nervous system. Laughing gas is only suitable for medical use; any other manipulation with it is dangerous. The use of the mixture involves monitoring the patient’s condition with special devices and an anesthesiologist. During surgery, it is always administered gradually, in small doses. An overdose of the substance threatens severe poisoning or permanent loss of consciousness. And the wrong concentration can even lead to death.

Every year Finns and Finnish language lovers celebrate Finnish Language Day on the 9th of April. If you hear that Mikael Agricola Day is also celebrated in Finland on this day, then you should not correct your opponent. These two holidays are identical, the only difference is in the years of their occurrence. So, in 1960, a holiday was established in the country in honor of Agricola. 18 years later, namely in 1978, the holiday began to bear the name Finnish Language Day. The exact date of birth of the reformer is unknown to historians, so this Day was celebrated not on his birthday, but on the day of his death. Mikael died in 1557 while moving from Moscow, from where he was traveling with the Swedish delegation after negotiations in connection with the establishment of peace between Russia and Sweden. Michael Agricola was a bishop, educator and reformer who lived in the 16th century. He was awarded such attention due to his enormous merit: in 1543, thanks to him, the first Finnish ABC saw the light of day. The basis of this book was the Karelian dialect. Residents of Finland rightfully consider this year to be the year of birth of Finnish writing. The reformer did not stop there and published a prayer book a few years later. Then he translated the New Testament into his native language. In other words, the educator devoted most of his life to translating texts that were relevant at that time into Finnish in order to develop literacy and writing among the population. The Finnish Alphabet contained not only the alphabet and numbers, it also included the main fragments of the Catechism. Thus, the book contained the basics of what Christian priests taught at that time. It is not without reason that in one of his books Agricola points out that his main merit is only the transfer of his native language to paper. And the language itself existed long before that. Traditionally, every April 9, the national flag is raised throughout the country, however, this day is not a day off. The holiday in honor of the father of written Finnish is celebrated in educational institutions with competitions, as well as seminars and lectures. Despite the fact that the Finnish ABC in its original form has not reached the present day, even in fragments, libraries on this day organize public readings of these books, as well as present new ones. Paying tribute to memory, descendants bring flowers to the place of death and monuments of Agricola. In 2007, collectible silver coins were issued in denominations of 10 euros.

Georgia is considered a country that is famous for its multinationality. The traditions and culture of the people of Georgia are widely diverse. National Unity Day is considered an important date. On April 9, 1989, events of historical importance took place in the capital of Georgia. In 1989, open-ended rallies were actively held with the aim of restoring Georgia's independence. Various structures and equipment were used to construct barricades; protesters used trolleybuses and public transport. April turned out to be a tragic month for the residents of Tbilisi. The events that took place left an imprint on the life of every resident of the capital. The number of protesters was approximately 10 thousand people. After there was no response to the call of the head of the city police department to leave the square, a mass displacement began. The blocked exits by vehicles blocked the path, making it impossible to leave the ominous place. The people were seized with panic, a crazy stampede and chaos began. Early in the morning of April 9, units of internal troops attacked the people. 16 people died, among the dead were women and children. More than 200 people were injured. Due to the stampede, 25 people were taken to local hospitals. The events that took place are closely connected with the Georgian-Abkhaz conflict during the perestroika period. On April 9, 1991, a referendum was held, after which the parliament created a decree on the restoration of the people's independence of the country, the so-called Georgian statehood. A 40-day mourning was declared in protest of the dispersal of the protesters, and a people's strike began. On April 9, 1989, a state of emergency was declared in the capital. Despite everything, protesters continued to demonstrate. In memory of the victims, to this day, residents bring wreaths and flowers to the scene. Every year, Georgian National Unity Day is officially celebrated on April 9.

Baha'i Holidays - Feast of the Nineteenth Day of the Month of Jalal

On April 9 (March 27, old style), according to the folk calendar, Matryona Nastovnitsa (Nastovitsa), also nicknamed Polurepitsa, is celebrated. The Matryona holiday is named in honor of Saint Matrona of Thessalonica, a martyr who suffered for her faith in Christ in the 3rd-4th century. On this date, Orthodox residents honor her memory in the church. Matrona was a slave to the rich Jewish woman Pautila. The girl professed Christianity and attended church secretly from her mistress. When she found out, she ordered Matrona to renounce Christ, but the slave refused, declaring that the Lord had turned his back on the Jewish temples. In a rage, Pautila beat Matrona, first with her fists, then with a stick, tied her up and locked her in a closet, where the soul of the martyr went to God. Matrona's body was thrown from a cliff, but Christians picked it up and buried it with honor. A church was built in her honor, and the relics of Saint Matrona had the properties of miracles. Saint Matrona was the patroness of housewives. In the morning they went to the temple and lit a candle for her. They prayed to the saint for help in coping with the abundance of household chores. The people called Matryona Nastovitsa. This concept was associated with an ice crust on the snow - an infusion formed after a thaw and frost. Where the snow lay, the women took out fabric canvases for the last time to be whitewashed. On the snow under the sun's rays they became lighter and softer. And Matryona was called Half-repitsa because the owners went down to the cellars and checked the remains of food. More attention on this day was given to the turnip, the vegetable breadwinner for the family. Its best root vegetables were set aside for seeds, and spoiled ones were examined and, if they were still usable, taken to the kitchen. Turnips were used not only for food, its juice or tincture was used for medicinal purposes, because it had antiseptic, anti-inflammatory and diuretic properties. At Matryona Nastovitsa, the peasants looked out for the return of the lapwings from the warm lands. It is a bird of black and white plumage with a crest on its head, slightly larger than a jackdaw. Returning to their native places, lapwings brought warmth with them. People also valued them for exterminating insects that harm the household. The signs on Matryona Nastovitsa spoke of the coming weather. If a lapwing was heard singing before sunset, then the next day was expected to be sunny. His close flight to the ground foreshadowed days without precipitation, and if he screamed at the same time, then a dry summer was approaching. Seeing seagulls above your home meant that the ice on the rivers would soon melt. The frost that fell in the morning, plus the foggy haze, promised a good harvest when harvesting.

Tunisia Holidays - Martyrs Day

Vasanta Navratri - spring nine nights of the Mother Goddess in Hinduism (Vaisakhi)

Orthodox holidays on April 9:

April 9 (March 27, old style) is celebrated in the church calendar as the Day of Remembrance of the Martyr Matrona of Thessalonica. The exact dates are unknown, but Matrona lived approximately in the 3rd-4th centuries in the city of Thessaloniki (now Thessaloniki, Greece). The girl served with the noble Jewish woman Pautila, the wife of a military commander in Thessaloniki. From her youth, Matrona professed Christianity and prayed to the Lord daily. When a Jewish woman visited the synagogue, the maid ran to the church in secret from her. During the Easter period, the servants reported to the mistress about Matrona, and she ordered the girl not to go to a Christian church anymore, but to choose a synagogue instead. But the maid objected, declaring that the Lord had retreated from the synagogue. Matrona also expressed that her life does not belong to her, but her soul is free to choose who and where to pray. In a rage, Pavtila beat her subordinate, tightly tied her hands and feet with ropes and locked her in a closet for four days. Having opened the closet, the hostess found Matrona in prayer on her knees, and her body was freed from the ropes without a single abrasion. Then anger covered Pautila, she ordered the martyr to be beaten with sticks and again locked up without food, so that she would change her decision. The saint was unable to survive such torment; her pure soul went to God. Fearing reprisals for murder, the owner ordered the girl's body to be thrown off a cliff to hide the evidence of the beating. When the city residents found the dead Matrona, she was buried in a Christian manner. Subsequently, God's punishment overtook the tormentor; she accidentally fell off that cliff and fell to her death. In honor of Saint Matrona, Bishop Alexander, nicknamed Solunsky, organized the construction of a temple. The relics of the holy martyr were transferred to it, where they became famous for their miraculous properties.
