On October 23, marketers and representatives of PR agencies celebrate Advertising Worker's Day. Despite its history of a couple of centuries, the holiday remains unofficial. Advertising in Latin is reclamare, to shout out. The ability to inform the public about a product or service in a catchy, concise, catchy way is an art. The first attempts to promote goods on the market were made by merchants at the beginning of the 13th century. They hired people who, with loud calls and colorful descriptions, invited passers-by to the shops. The development of the industry led to the fact that advertising soon filled the cities: posters, leaflets, barkers, and later specialized bureaus began to appear, providing services for promoting products. After the events of 1917, the state took sole possession of the right to advertising. During the period of the new economic policy, V. Mayakovsky became the best advertiser. His passionate and convincing slogans are still used as an example to future creators of the trading engine. The period of stagnation has become an unprofitable time for PR specialists. Advertising banners reported only about the excellent company Aeroflot. The collapse of the USSR became a new milestone in the development of the advertising business. The early 1990s became a runway for many. The lucky ones include those in the advertising industry. There were legends about their income; it was said that, having concluded a couple of successful deals, agents bought apartments in the center of Moscow. The quality of advertising at the end of the 20th century leaves much to be desired, but the scale is amazing. In 1994, A. Ardasenov, an ordinary student at an undistinguished university, got a job as a PR agent in the print publication Delovoy Express. He worked hard and one day in his diary he found an entry about his first 10-dollar fee, which he received on October 23. Alan decided that this was very symbolic and told his colleagues that October 23 would now be the day of the advertiser. For some time, the holiday was celebrated in narrow circles, but, with revolutionary PR breakthroughs, the number of people involved in it also increased. By 2001, A. Ardasenov became the director of a large agency and decided to celebrate the day of the advertiser on a grand scale. For this purpose, one of the capital's Matrix clubs was rented, at Varvarka, house 14. The holiday was successfully repeated in 2002 in another Moscow club. Since 2003, PR Day has become popular in many cities of Russia and neighboring countries. Modern advertising has little in common with the primitive slogans of the last century. Specialists do not appear out of thin air, but are trained in advertising skills at universities. There is a separate industry - political advertising, the highest echelon. Colorful posters and intriguing videos encourage buyers to purchase more and more goods and services. Opponents of PR are sure that such a number of products on display does more harm than good for the average buyer. While professionals and skeptics are discussing the need for advertising in the life of humanity, on October 23, everyone involved in the profession in one way or another celebrates Advertising Worker's Day.

In 2013, the first International Forum dedicated to the conservation of the snow leopard was held in Bishkek with the participation of representatives from 12 countries. Mammals of the cat family live in Southern Siberia, in China, India, Bhutan, Kazakhstan, Pakistan and a number of other countries. The animal is endangered, which is why it was listed in the Red Book of the USSR back in 1978. The date of the international forum, October 23, became International Snow Leopard Day, which is also called the ibis. The habitat of the predatory mammal is the high mountainous regions of Central Asia. The ibis is valuable for its uniquely colored fur, which is why it often becomes prey for poachers. One of the problems is the narrowing of its natural habitat due to the increase in areas for grazing livestock. One of the threats to the life of ibises is climate change on the planet - global warming. International Snow Leopard Day calls for attention to the decline in the leopard population and the risk of extinction of this rare species of the cat family in the future. The total number of ibises in the world ranges from 3-7 thousand individuals. It is difficult to say more precisely due to the remoteness and altitude of the predators’ habitat - 5000 m above sea level. About 80 snow leopards live in Russia. 50 of them were recorded by video cameras and identified by a pattern on the skin, which is unique to each animal, like, for example, the color of giraffes. Counting snow leopards in Russia and the Siberian ibex, which the ibis hunts for food, has been carried out annually since 2017 at the initiative of WWF. In 2017, the next International Conference on the conservation of ibises and their ecosystems was held in Bishkek. Russian representatives of WWF took the initiative to use the mammal monitoring system used in Siberia and other countries of the world. To do this, automatic cameras are distributed among the sectors of the range where leopards are most often observed. The collected data is subjected to computer analysis. The inaccessibility to zoologists of the areas where the ibis lives is the main reason that it is one of the least studied mammals of the cat family. International Snow Leopard Day, which falls on October 23, aims to raise awareness and prevent the extinction of the animal's population.

International School Library Day is a fairly young holiday; it began to be celebrated in Russia in 2008. Librarians try to popularize reading books and libraries among students. In 1999, on the recommendation of UNESCO, School Library Day was organized. The goal of the project is to involve the public in the preservation and formation of literary reserves of school library funds. 6 years later, Peter Jenko, head of the International Association of School Libraries, approved the holiday. School libraries play an important role in the educational process. People come here before the start of the school year: inhaling the aroma of printing ink, they fill their backpacks with textbooks. First-graders are taken to the library for lectures about good and evil and getting to know literary heroes. In the silence of the reading room, high school students are poring over abstracts. In the back of the rows, teachers leaf through specialized literature. Despite their importance in educational and educational activities, school libraries are often not in the best condition. The lack of modern fiction, masterpieces of world classics that require replacement, and poor technical equipment are the main problems of school reading rooms. Librarian is one of the oldest professions. The first specialists appeared in 2500 BC, when the stock repositories were a warehouse of papyrus scrolls and clay tablets. Masters of storage and record keeping were then called scribes. The word “librarian” was first used in Ancient Greece, and it meant a collection of books. Slaves worked in this difficult field. In the Middle Ages, the initiative was seized by the monks. They classified books, kept order in the storage room, and rewrote church dogmas. The first large libraries appeared during the Renaissance: L. Medici and the Vatican. In Russia, the development of the profession began in 1307, when Y. the Wise gathered scribes for a painstaking census of Greek originals. The responsibilities of a school librarian of the 21st century include not only issuing textbooks and searching for books, but also: • record keeping; • classification of books; • compilation of bibliographic reference books; • control over the condition of publications. Despite the abundance of electronic media that allow you to read books, the aroma of rough leaves and the silence of reading rooms are still popular. Officially, the event is celebrated on the 4th Monday of October, but in fact, in most countries, an entire month is dedicated to school libraries. In October, they carry out such events as:• collecting waste paper;• reading aloud;• discussing literary characters;• voluntary donation of books to school;• bookcrossing. Seminars, conferences, and international congresses are organized for librarians.

Wine is often called the nectar of the gods. The popular alcoholic drink is produced both on an industrial scale and at home. On October 23, an unusual holiday is celebrated all over the world - Garage Driver's Day. At the origins of the tradition of producing small batches of products made from their own vines in family wineries is a Frenchman of Algerian origin, Jean-Luc Tunevan. He bought in 1991 600 acres of vineyard in Saint-Emilion in the Bordeaux region. The enterprising master carried out the processing and production of wine in a house the size of a garage. Monsieur Tunevan sold the products of the farm in his own bar. The first 1,500 bottles, priced at 62 francs (equivalent to 13 euros) each, sold out very quickly. After 6 years, the value of Chateau Valandraud, named after his wife's surname "Valandraud", increased 7 times. In 2012, the brand was included in the classification of Saint-Emilion wines. The concept of “garage winemaking” was officially recognized and consolidated. In different countries of the world, masters who personally produce and sell wine to consumers are called differently. In France, garage producers are called micro-cuvee, in Spain - Bodega Familiar ("family winery"), in Switzerland - vigneron encaveur (from cave - cellar). In most countries there are associations of independent winemakers. The tradition of producing wine in small family wineries is not the exclusive domain of French or Italian winemakers. In our country, such trademarks as “Serdyuk’s Dacha” are widely known. The drink from a small winery located in Novocherkassk does not contain sulfur dioxide or other preservatives. Every year, the family enterprise produces about 10,000 bottles of wine with a unique taste and aroma from Tsimlyansky grape varieties Saperavi and Rkatsiteli. Garage Driver's Day is celebrated annually by the founder of the Vina Bani brand, Yu. Khimichev. His micro-winery was founded on the Don in 2010 in the premises of a former farm bathhouse. The holiday is also professional for A. Mamonov, a hereditary master from Tsimlyansk, who produces about 900 bottles of the drink with a bright aroma and rich taste. To preserve the natural taste, no preservatives are added to the wine. One of the oldest farms in Russia was founded in 1990 in the Lower Volga by garage owner D. Gusev. It produces wine in quantities of up to 10,000 bottles per year from autochthonous vine varieties (Krasnostop Zolotovsky, Marinovsky, Sibirkovy, etc.). The estate also produces “Assemblage” - a sparkling brut aged for at least 9 months, produced using classic champagne technology. Micro winemakers are engaged in processing raw materials and bottling drinks at enterprises located on the territories of private households. The small volume of alcoholic beverages produced per year is due to the size of the farm, manual harvesting and sorting of vine bunches. The wines are made using ancient technologies and unique family recipes that are passed down from generation to generation. Professionals are proud of the quality and taste of their products, raising their glasses in honor of Garage Day on October 23.

Parties, corporate events, festivals, weddings, team building trips and banquets require careful preparation and the participation of professionals in this process. Event organizers give people bright emotions and good mood. Their scope of activity also includes the preparation of holiday shows, conferences, graduations, scientific forums and other meetings in a festive atmosphere. October 23 is Event Organizers Day. American event guru Joe Golblatt believes that the profession appeared in the mid-twentieth century. thanks to the opening of the first Disneyland in the United States. Over time, the organizers began to deal not only with entertainment events, festivals and concerts, but also with exhibitions, master classes, wine tastings, seminars, promotional tours and charity events. The presence of a professional will make not only birthdays and anniversaries, wedding anniversaries and housewarmings unforgettable. Specialists in organizing entertainment, sports and special events help customers develop their business. Inviting an event manager to hold a presentation, conference or forum has a positive effect on the company’s image and business reputation in the eyes of partners. Team building events and Family days - holidays for employees' children - contribute to team cohesion and improved performance indicators. The wishes of the director of the company or the hero of the occasion, the birthday boy and the hero of the day, are not enough for the holiday to go off without a hitch. Large-scale events that require the involvement of specialists from various fields of activity are difficult to organize for a person without experience and relevant skills. The success of holding an international conference or business training with two thousand participants guarantees that you turn to professionals. An event manager develops a concept for children's and adult parties, competitions or business meetings, writes a script, constantly generating ideas and searching for ways to bring them to life. The specialist is responsible for literally everything: sending out invitations to participants, creating a menu for the buffet and managing the service staff. A true professional embodies the wishes of the customer and achieves the assigned tasks, taking into account the interests of the target audience, the allocated budget and other factors. A manager must be distinguished not only by creative thinking, but also by stress resistance, resourcefulness and entrepreneurship - be able to quickly make decisions under force majeure circumstances. The success of a party, concert or company anniversary is a team effort. Lighting specialists, screenwriters, sound engineers, artists and musicians work together with the event organizer to bring the idea of ​​the holiday to life. Therefore, an event manager, among other things, must be sociable and able to work in a team. All people involved in organizing events, colleagues, customers, relatives and friends are congratulated on October 23 with Event Organizers Day.

The International Association of Weights and Measures has approved quantities that are used to calculate time, distance, mass of objects, and the strength of light energy. One of the units of measurement in the SI system is the mole. With its help, the amount of a substance is determined, or more precisely, the content of molecules, atoms or ions in one gram under normal physical conditions. From the course of physics and chemistry it is known that per 1 mole there are as many tiny particles as there are atoms contained in 0.012 kg of carbon nuclide with atomic mass 12. The calendar of solemn dates includes holidays dedicated to various mathematical constants - the number Pi (International Pi Day), square root, etc. October 23 is celebrated as Mole Day. Mole Day appeared in 1991 thanks to chemists from Wisconsin. One of them, Maris Oyler, established the National Moth Foundation on his own. In 1991, a holiday dedicated to one of the units of the system of weights and measures arose. The date of Prayer Day was not chosen by chance. It is directly related to the Avogado constant - the number of atoms (molecules or ions) contained in 1 mole of a substance. The approximate index of this constant is 6.02⋅10 to the 23rd power. Therefore, Prayer Day is celebrated twice a day on October 23 - at 6:02 in the morning and the second time at 18:02 in the evening. Molecular physics studies the composition of substances in various states - from liquid and solid to gaseous. To solve problems, this science uses the methods of thermodynamics and statistical dynamics. The first branch of molecular physics was the kinetic theory of gases in 1858, which was developed by Ludwig Boltzmann together with other scientists. Long before them, in 1811, the Italian chemist Amedeo Avogado suggested that at a given pressure and temperature, the volume of a gas, regardless of its nature, is proportional to the number of atoms or molecules. Today this constant quantity is called a mole. The term mole, derived from the word “molecule,” came into use at the beginning of the twentieth century. Wilhelm Oswald, who became a Nobel laureate in 1909 for his discoveries in chemistry. The unit of measurement was introduced into the SI system in 1971. 20 years after this event, a holiday was established in honor of the moth. The celebration is celebrated by scientists, laboratory assistants, chemistry and physics teachers. During Mole Day, teachers conduct competitions, conduct experiments with students, and organize competitions for solving entertaining problems in which moles appear. Thanks to the initiative of chemistry teacher M. Oyler and funds collected by the National Foundation, the winners of school and university Olympiads receive valuable prizes and awards. On Moth Day, seminars and conferences are held, and feature articles are published in scientific journals of the American Chemical Society and other organizations.

Autotomy is characteristic of geckos, spindles and lizards. Throwing away the tail helps these representatives of reptiles escape from the enemy, sacrificing the least valuable part of the body. After a couple of months, this spinal appendage grows back. The main function of the tail is to participate in movement. It helps lizards, crocodiles, monitor lizards and iguanas crawl, swim and balance on a vertical surface. The tail of reptiles plays an important role in social behavior. With its help, individuals send signals to other members of the population and communicate their intentions and mood. With a thing in life: During the divorce, he left all his property to his wife. This is how a lizard throws off its tail to stay alive. “Tails” prevent a person from living like debts on exams and tests - a student. You should get rid of unnecessary ballast that pulls to the bottom. Apparently, this is the thinking behind the initiators of the Tail Drop Day celebration, which is celebrated on October 23. The phraseological unit “throw back your hooves” means going to your forefathers. The phrase “throw away the tail” does not carry a negative connotation; on the contrary, it symbolizes entry into a new world. Psychologists are convinced that the burden of the past prevents us from enjoying the present and living in the present moment - here and now. The holiday of October 23 is an excellent occasion to get rid of everything unnecessary that poisons existence. This could be a relationship that is depressing and not enjoyable, communication with toxic people who suck out energy and vitality. With a joke for life: Announcement: “Urgent!!! Who can lend a tail to a child for a matinee? Ready to buy. We received an order for a squirrel costume online, but there is no tail.” Ballast on a ship is a necessary thing, especially when there is not enough payload. Usually its role is played by intake water pumped into the onboard tanks, which is discharged before entering the port. With the help of technical cargo, the ship changes speed, rolls and performs other maneuvers. Life ballast in the form of depressing memories from the past or unfriendly people from the point of view of Buddhism and other religions is of great benefit. Even the most unpleasant situations and encounters are good life lessons. After a person has mastered them, it’s time to “throw the tail away” - leave the ballast overboard the ship before entering a new port. With a joke in life: What's the point of cutting off a student's tail? By the next session a new one will still grow. On October 23, you can part with both tangible objects, old clothes and other things that have been collecting dust in the closet or attic of the house for years, as well as with internal experiences. These may be doubts about your own abilities, parental attitudes and their expectations that are not in tune with your life goals. To say goodbye and easily part with everything superfluous that prevents you from moving forward, a funny holiday that has a deep philosophical meaning - Drop Your Tail Day - encourages you.

The national holiday received its name in honor of the holy martyrs Eulampius and his sister Eulampia, who lived in the 4th century near Constantinople. At this time, healers went for herbs; rue, a plant with magical properties that protects children from evil spirits, was especially valued. To do this, the rue was hung from the very ceiling of the home.

The first diamond weighing 0.546 carats, found in Yakutia, was cut at the Suntar plant - at that time a joint venture with Japanese equipment manufacturers, Sakha-Japan Diamond. A 0.270 carat diamond was produced from the stone on October 23, 1992. The initiative to create diamond processing factories in rural areas of the republic in the 90s did not meet with approval from local authorities. However, as time has shown, the involvement of Japanese companies in organizing enterprises for processing and cutting precious stones turned out to be a strategically correct decision. In the villages of Nerbe, Suntara and Verkhne-Vilyuysk, diamond processing factories appeared, which used high-tech equipment supplied by partners from the Land of the Rising Sun. In their presence, in 1992, the first Yakut diamond was ceremonially cut. The stone that laid the foundations for a new diamond-processing industry was named “Star of Suntara.” This historical moment served as the reason for the establishment of the holiday. On October 23, Yakutia celebrates the Day of Jewelry and Diamond Cutting Industry Workers. The professional holiday appeared in 2010 after the decree of the President of the Republic of Sakha was issued. The industry is considered one of the key ones in Yakutia and is the calling card of the region. A full production cycle is carried out on its territory - from the extraction of diamonds and other precious stones to processing and manufacturing of jewelry using modern technologies. For the first time, public attention was drawn to the problems of the diamond cutting industry in 2008 at a round table attended by local authorities, industry representatives and journalists. One of the results of the meeting was the establishment of Jeweler's Day, which was celebrated for the first time in the republic on September 28, 2009. The company "Gold of Yakutia", the flagship of the region's jewelry production, and other enterprises are suppliers to the domestic and European markets of products made from precious stones, made by true masters of their craft. Thanks to the work of professionals and experience that is passed down from generation to generation, Yakutia is the leader in the Russian diamond cutting industry. The deposits and underground mines of the republic are considered unique due to their high value. Thus, the International pipe, located in the Mirny region, produces 350 tons of ore with a diamond content of 8 carats per ton. In foreign mines this figure is 0.3 carats per 1 ton. The explored reserves of stones will provide enterprises of the Sakha Republic with work for the next 40-50 years. The production schedule for some mines is scheduled until 2042. Today, production at previously mothballed deposits is being resumed, and new deposits of natural resources are being searched for. This will lead to the creation of new industrial areas and jobs. This means that an increasing number of professionals employed in the industry will annually receive congratulations on the Day of the Jewelry and Diamond Cutting Industry Worker in Yakutia.
