Weddings, receiving government awards, dinner parties, graduations... For these and other special occasions, it is customary to wear a suit. According to etiquette, it is worn for business negotiations and interviews, when visiting a restaurant, opera and ballet.

We are accustomed to the fact that global dates associated with thousand-year traditions, great victories, and most important events receive the title of international holiday. Therefore, at first glance, World Egg Day cannot be considered a serious holiday. And yet it has existed and been celebrated since 1996. The date was established by the IEC (International Egg Commission) at the next Vienna Conference. The main prerequisites for the declaration of World Egg Day were:• promoting international cooperation between all sectors of the egg industry;• encouraging the development of quality statistics on market research for eggs and egg products;• promoting the harmonization of international marketing standards;• encouraging hygienic production;• studying and assisting in the problem of international trade;• promoting the work carried out by international agencies in countries where nutrition and food security are insufficient;• encouraging countries to increase the consumption of eggs and egg products.• introducing activities to improve the lives of laying hens;• encouraging actions that promote conservation environment. All of the above proves that the consumption of eggs in modern conditions covers many universal human problems. These include: low standard of living, food insufficiency, harmful ecology, cruelty to animals, suppression of important information, precarious economic ties and much more. It was typical for the 90s of the 20th century to unleash unverified or incomplete information on the media. Thus, when talking about salmonellosis, a disease caused by eating eggs, they were silent about the fact that heat-treated eggs are completely harmless. And information about increased cholesterol for egg lovers turned out to be far from the truth. After all, egg cholesterol is very low in content, and the beneficial substances completely compensate for the harmful threat. The truth is that eggs are a wonderful dietary protein product containing many useful substances and vitamins. The beneficial effect of eggs on the human body can be shed light by the fact that the champions of longevity, the Japanese, are the country with the highest consumption of this product. People who managed to live to see their 100th birthday note that eggs were the basis of their diet. World Egg Day is celebrated on the second Friday of October. For many countries, this is a reason to launch a broad media information campaign. In America, television broadcasts recipes for unique egg dishes all day long. Austria has distinguished itself by decorating cities with balloons with the inscription: “An egg - every day.” Hungary invites everyone to come and enjoy the famous egg goulash. In many countries around the world, festivals, promotions, flash mobs and concerts are held that highlight the benefits of eggs and egg products, and inform about the problems associated with the production and trade of this product.

Representatives of radical feminism oppose gender roles and the rules associated with them that are imposed by society on the fairer sex. Some of the symbols of women's oppression include heels of shoes, thongs and such an element of underwear as a bra. October 13th is No Bra Day, a holiday that encourages women to throw off the shackles of tight clothing, take a deep breath and pay attention to the problem of breast cancer. Not only feminists, but also some mammologists and specialists in other branches of medicine believe that a bra does not affect the shape of the breast. A woman’s mammary glands lose shape not due to irregular wearing of a bra, but due to genetic predisposition and the elasticity of the connective tissue. The ligamentous apparatus of the pectoral muscles is trained and strengthened without a bra. Moreover, wearing this piece of clothing is often associated with the development of mastopathy. Therefore, feminists believe, a bra, like daily makeup, should be considered a relic of the past - a time when women wanted to please men without taking into account their own interests and personal comfort. No Bra Day is celebrated with a number of events that raise awareness of breast cancer. Early diagnosis of the disease makes it possible to prevent its development, which means preserving a woman’s health and life. The symbol of the celebration was a pink ribbon. On October 13, free consultations and examinations are held at oncology clinics and mammology centers. On this day, public buildings in various countries around the world are illuminated pink. In honor of No Bra Day, it is also customary to actively disseminate information about malignant breast diseases and publish thematic photos with hashtags on social networks. Muslim organizations in the United States, as a sign of support and solidarity with the feminist movement, hold Pink Hijab Day at the end of October. Somewhat later, on October 15, Breast Health Day is celebrated at the initiative of WHO. This celebration, like No Bra Day, encourages women over the age of 40, i.e. those who are at risk should not delay visiting a mammologist to diagnose the disease in the early stages. Bra Refusal Day has been celebrated since 2011. In honor of the holiday, the bravest representatives of the fair sex post online photos of themselves without underwear, which, according to feminists, constricts their breasts. Other women are studying and spreading awareness about breast cancer, its causes and consequences. Despite its apparent simplicity and frivolity, No Bra Day is far from a funny holiday. He draws attention to the problem of diagnosing and treating such a serious pathology as breast cancer.

Problems with blood clotting lead to blockage of blood vessels. Blood clots forming in problem areas prevent the free circulation of oxygen and contribute to the accumulation of metabolic products, including lactic acid. Blockage of blood vessels is the main cause of strokes and myocardial infarctions. The success of treatment and prevention of deadly diseases depends on people's awareness of the causes of their occurrence and the characteristics of their development.

Psychologists believe that one of the ways to achieve harmony and internal balance is the ability of a person to pamper himself. People who have adopted this recipe are successful in building personal relationships and careers; they easily overcome various obstacles and difficulties. The pleasant moments in life that we give to ourselves allow us to enjoy life without regard to the opinions of others. October 13 is Pamper Yourself Day, a holiday that encourages people to pay attention to the needs of body and soul. Taking care of yourself is not selfishness and not indulging a person’s weaknesses or momentary desires. It is not for nothing that the second commandment of the Gospel says: “Love your neighbor as yourself.” In order to share the light of the soul and the heat of the heart with others, appreciating them, a person must become a harmonious person. That is, to live in love and harmony with oneself. Conscious encouragement allows you to begin to recognize your own needs and better control them. To do this, it is necessary to achieve a balance between the three egos that exist, according to psychologist Eric Berne, in each of us: Adult, Child and Parent. How to start pampering yourself, what steps should you take in this direction? 1. Find out what you want - remember everything: from momentary desires to childhood dreams. Yes, buying a coveted toy looks ridiculous, but the inner Child will be happy from this gift. 2. Stop saving on yourself. Remember, we are not so rich that we buy cheap things. This does not mean that you need to spend your entire salary on expensive cosmetics or clothes. However, allowing yourself to buy something that was previously prohibited due to complexes and negative attitudes coming from childhood (Parent taboo) is still worth it. 3. Change your attitude towards shopping (act like an Adult) - stop feeling shame and guilt from purchasing things. 4. Make time for hobbies and interests. Taking a break from your daily routine, you will forget about the blues and bad mood. Pamper Yourself Day is especially relevant for those who, due to internal beliefs and attitudes, have completely forgotten about their own interests. Remember, any sacrifice must be justified by objective circumstances. The ability to pamper yourself gives a person additional strength and reveals new character traits in him. Anyone who is satisfied with life attracts positive energies and positive vibrations into it. It's not easy to learn, but it's never too late to start - for example, during the Pamper Yourself Day!

International Loser Day is celebrated on October 13th. The holiday was invented in 2010 in Finland - the government was worried that failures would stop people from experimenting in the future and would suppress the spirit of creativity, initiative and entrepreneurship. You need to understand that a bad result is also a result; a person has gained at least experience. Since childhood, we have been told that success is good and failure is bad. Therefore, we are ashamed of our failures, we do not want to tell others about them, because in childhood we were told that failing was bad, sometimes we were even scolded for our mistakes. For example, for torn trousers or for getting a bad grade at school. Without risk and mistakes there would be no success, because if you don’t fall off a bike, you won’t learn to ride it. On this day, it is customary to tell others about your failures, share failures and stories of complete fiasco. Contrary to stereotypes, admitting failure is not a sign of weakness, but a manifestation of the strength of your character. Talking about your failure will be a good lesson so as not to repeat similar mistakes in the future. History knows many examples when at first a person suffered a severe fiasco, but then learned from his mistakes and became successful. As long as a person makes efforts to improve and struggles with mistakes, he develops. It’s much worse to dwell on your failures and think that nothing good will happen in life anymore. There are several options for celebrating Losers Day: 1. Invite several like-minded friends who also don’t mind telling each other about their failed moments in life. 2. Write a post on a social network where you detail the story of your fiasco. 3. Make a video story about your failure and then post it on a social network or on your blog. The most important thing is to sincerely share with others about your failed moments in life. You need to think that your story will be instructive for someone, and that person will be able to avoid your mistakes. This will save him time, money and resources. Topics can be very different: work, personal life, travel, repairs. The most important thing is to choose the right topic so that the audience appreciates it. For example, an auto mechanic will not be very interested in hearing about the disastrous financial transactions of a stock market broker. Some stories should not be told at all due to ethical considerations. For example, about your failures in your sex life. It is better to leave them for a specialized doctor.

On October 13, it is customary to celebrate International Skeptics Day. Skeptics are people who question not only everything little studied and not fully understood, but statements that most do not argue with. For true skeptics, there is nothing that cannot be questioned. They will be able to make mountains out of molehills and also prove that 2+2 equals 5. It is a pity that society considers doubters to be bores, since their long thoughts and logical conclusions will really make many bored. But thanks to doubts, new theories and different views of the world appear. If there were no skeptics, then we would think that our planet is flat and stands on three pillars. It was the doubters who began to doubt what for the majority then seemed to be the truth. Thanks to skeptics, civil marriages, atheists, and online stores appeared. Some doubted the need to formalize relationships for a happy marriage, others went against the mass introduction of the population into religion, and others refuted the myth that the computer and the Internet can be used exclusively for games and entertainment. Thanks to doubts, life becomes better and the world develops. Therefore, we can consider skeptics boring as much as we want, but deep down we still respect them. On this day you can be a skeptic and don’t be afraid to seem boring. It is best to get together in a company of like-minded people to argue about the origin of life on Earth, think about the imperfections of the government system, argue about the treatment of supposedly incurable diseases. If you happen to celebrate Skeptics Day alone, then you can watch TV shows that debunk myths or pseudoscience. For example, "MythBusters". You can also look for evidence to support the veracity of some of the stories you've been told. Try not to accept anything as truth on this day. Try to doubt everything, even the most obvious things. Who knows, maybe these doubts will prompt you to a certain idea that will help you make a discovery or at least improve your life or living conditions. For example, you may doubt what is more profitable: renting an apartment or taking out a mortgage; drive on gas or gasoline; formalize a relationship or live in a civil marriage. You can write down your most interesting conclusions and then share them with friends. It is advisable to present information in a humorous manner so as not to seem too boring or abstruse. By the way, another International Skeptics Day is also celebrated every Friday the 13th.

There are many unusual, humorous and amazing holidays. Among them, it is worth noting October 13 - Falling Trees Day. Perhaps many people have not even heard of the existence of such a holiday, which is not surprising. It appeared relatively recently. It is still not known for certain who exactly decided to establish it. Most likely, this is a truly popular idea, so it is impossible to establish the exact name of the author or authors. This holiday is widespread mainly in Russia, but it is also celebrated in the Asian region. It is known that, for example, residents of China are also interested in it. By the way, this is not at all surprising. The fact is that trees falling asleep and preparing for a long hibernation are quite compatible with the Chinese philosophy of pacification. Traditionally, it is in the religions of the Asian region that much attention is paid to the spirits of nature. This is typical, for example, of Shintoism in Japan, Buddhism, Confucianism and other areas. This holiday has also taken root in Russia, since many people find something poetic and touching in the coming autumn. It’s like a harbinger of a small, temporary death, bringing a slight sadness. But next spring the trees will definitely come to life again, and everything in this world will repeat itself all over again, as it has been happening for tens of thousands of years. That is why some call the Day of Falling Trees not just entertaining and comic, but also philosophical. And some see a slight sadness in it. There are no clear instructions on how exactly this day should be celebrated. Since the holiday is relatively new and unusual, it is necessary to celebrate it as creatively as possible. It is known that some creative people, for example, artists, photographers, poets and simply people with a fine mental organization prefer to spend this time in parks and squares, on the banks of reservoirs, watching how red, yellow, brown leaves slowly float across the water. Of course, a lot depends on the weather that day. In many regions, October is already considered a rather stormy month with a lot of precipitation and winds. Therefore, not all people have the opportunity to go to nature, to the forest, to the park on this day, in order to wish the trees a peaceful winter sleep in their hearts. By the way, this day is not ignored by ecologists and representatives of organizations in one way or another connected with the protection of flora and fauna. On October 13, why not think about how fragile the natural world is and how much it depends on humans? It is known that every year our relatively small planet irreversibly loses 26 million hectares of forests. The area is comparable to the territory of Great Britain! If human activity continues at the same pace, then the Day of Falling Trees will indeed turn out to be very sad for our descendants. But for now you can celebrate it the way you want, that is, depending on your mood. Perhaps, on October 13, someone, on the contrary, will want to have as much fun as possible by having a picnic in nature, among the trees, with family and friends. Some organizations have dedicated some environmental or charitable events to coincide with October 13th. Already a classic can be called such useful measures as planting trees in disaster zones to prevent landslides. In addition, it is quite possible to spend a cleanup day by going to the nearest forest or park area. It has already become a good tradition to combine good rest, festive fun and helping nature, animals, and the environment.

One of the most famous performances of The Beatles was the 1963 concert, which the musicians gave on October 13 at the London Palladium. Fans, whose behavior bordered on madness, screamed and shouted, not wanting to let their idols go at the end of the event, blocking the way to the car.

On this day, all Orthodox believers remember the great Saint Michael, who at the end of the 10th century in Korsun baptized Prince Vladimir himself. This holiday is directly connected with straw, which was considered a source of strength; people slept on it, stuffed pillows with it, and fed livestock. Therefore, the main task on October 13 for everyone was to burn the old straw and fill all things with new straw or specially charmed field herbs.

What is the unluckiest day of the year? Lovers of omens who are afraid of black cats and women with empty buckets will unanimously say that this is “Friday the Thirteenth.” The worst day is when it’s dangerous to even leave the house - a brick will definitely fall on your head or your heel will get stuck in the drainage grate. Is this day really so dangerous and where did the assumption come from that bad luck triumphs on Friday, which falls on the 13th of any month? Many researchers agree that Friday, which falls on the 13th, became unlucky only at the beginning of the last century. 13 doesn't stand out in any way from other integers, but that's according to mathematicians. Ordinary people give it a certain sacred meaning, due to the huge number of superstitions and myths that surround it. In our country, 13 are called the “devil’s dozen.” Some researchers suggest that the number received its terrible name because of the Last Supper, which, as we all remember, was attended by thirteen people - Jesus Christ and his twelve disciples. You probably don’t need to tell anyone what happened after that. One of the diners died on Friday, so subsequently, when thirteen people gathered at one table, a fourteenth guest was specially invited. According to superstition, if this is not done, then one of those present will definitely die within a year. Many later, the myth spread that Satan, before his overthrow from heaven, was the thirteenth angel. This version has quite a lot of supporters, but it is not confirmed in ancient treatises. Dennitsa was the first, most beautiful and beloved angel of God, who believed that he could become equal to him, for which he paid. There are also legends that on the 13th Eve ate an apple, and Cain killed Abel. Some associate the notoriety of Friday, which falls on the 13th, with the Knights Templar. It ceased to exist immediately after the order for the arrest of all participants, which the French king announced on Friday, October 13, 1307. Others associate the fatal number with the coming apocalypse, when the end of the world will come. There are many different pseudo-teachings and predictions on this topic. For some peoples, the number 12 was sacred, and the 13 that followed it was associated with the unknown and danger. Although there are many versions and there is no consensus on why everyone hates the number 13 so much, one thing is clear - the roots of this phenomenon should be sought in religious prejudices. The fear of Friday the thirteenth has reached alarming proportions and become a mass phenomenon. In some houses, the numbering of floors is broken so that no one lives on the thirteenth. For example, immediately after the 12th floor there may be 14 or “12+1”. Some hotels resort to the same tricks, but with room numbers. Many ships do not have thirteen cabins, and many aircraft do not have thirteen rows. As many people know, people who put their lives at serious risk are very superstitious, so shipping and airlines can be somewhat understandable. One can also be sympathetic to athletes who understand perfectly well that much in competitions is decided not only by their talent and skills, but also by luck. However, there are many examples in history when, for example, football players wore T-shirts with the number 13 and at the same time achieved great success. Fear of the number 13 is a Western phenomenon. It even has its own medical name - triskaidekaphobia. But in Asian countries, no one is afraid of the number 13, because here they have their own terrible number 4 and the tetraphobia associated with it. The fact is that the hieroglyph with which it is designated is read almost the same way as the hieroglyph for “death.” The only difference is in the tones. What to do on Friday, which falls on the 13th, is up to everyone to decide for themselves. You can lock yourself at home and sit within four walls all day, but if luck has decided to turn its back on you, no locked doors or closed windows will help avoid the consequences of losing its favor.

International Skeptics Day is a floating holiday that occurs every Friday the 13th. The date was chosen because the day is associated with skepticism and superstition. This is a day to be skeptical, superstitious and doubt things. A skeptic is one who doubts everything or questions what many believe to be factual or true, such as scientific, religious or philosophical knowledge. Instead of accepting something at face value, skeptics look for more evidence and consistency in logic. The word “skepticism” comes from the Greek word “skeptomai”, which means “to think or reflect.” Skepticism is a method of inquiry, not a set of conclusions, beliefs, or faith. He argues that any belief is open to future revision because it is based on what the evidence shows in a particular period of time. Throughout history, skepticism has aided scientific research and the pursuit of knowledge. Skeptics have helped debunk false theories and hoaxes, such as the belief that the Earth is flat. There are two theories why Friday the 13th is associated with skepticism and superstition. The first refers to the Last Supper, which was held on the night before the crucifixion of Jesus Christ, and was attended by 13 people: Jesus and 12 of his disciples. The number 13 became associated with Judas Iscariot, who betrayed Jesus. This number is considered imperfect, unlike 12, a number that also represents the number of months in a year. The second theory why Friday the 13th was associated with skepticism and superstition has to do with the Knights Templar. Under pressure from Pope Clement V, King Philip IV of France arrested hundreds of these Catholic crusaders on Friday, October 13, 1307. It was alleged that recruits to the order were forced to spit on the cross, deny Christ, and engage in homosexuality during initiation. These allegations were unproven, but the knights were accused of moral and financial corruption, as well as of worshiping false idols, and were burned at the stake. According to legend, Jacques de Molay, Grand Master of the Templars, said before being killed: “God knows who is to blame and who has sinned. Soon disaster will befall those who sentenced us to death.” De Molay's words were seen as a curse that continued throughout time, meaning that Friday the 13th would continue to bring bad luck. Here are some ideas on how to celebrate Skeptics Day: • Be skeptical or superstitious about everything. Find out if something is true for yourself, instead of following what others have said about it. If someone makes a claim today, check whether it is supported by logic and evidence. • Watch Mythbusters or other shows that debunk pseudoscience and myths. • Check if some of the stories you were skeptical about are true by examining the evidence. • Meet other skeptics or interact with them online. By the way, Skeptics Day also has another fixed date - October 13.

Landslides and floods, earthquakes and mountain falls, droughts and forest fires are natural phenomena that are of an extreme nature. The consequences of hurricane winds, tornadoes, storms, volcanic eruptions and dust storms are familiar to residents of many countries around the world. Natural disasters cause great economic damage, lead to forced migration and loss of life.

The work of specialists in oceanography and navigation is the most important tool for supporting the activities of the country's Navy. Peter I was the first to declare the importance of research and description of lakes, rivers and seas. Without this, the Russian fleet and other state institutions cannot fully solve the tasks assigned to them. 100 years later, on October 13, 1827, a special Office of the Hydrograph General was created under the Ministry of the Navy. Its leader was Vice Admiral G.A. Sarychev is an outstanding oceanographer, author of maps of the Baltic, Okhotsk and Bering seas. A great contribution to the development of hydrography was made by Yu.F. Lisyansky and I.F. Krusenstern. With their participation, scientific work was carried out in the open ocean for the first time. The peak of research into water bodies in Russia occurred in the second half of the 20th century. The history of the hydrographic service is the history of the exploration of the World Ocean by Russian navigators. Today, the collection of navigation maps includes more than 8.4 thousand copies with a detailed description of the bottom topography, physical characteristics of water masses and other parameters. Hydrometeorological support is a subsystem of the fleet's combat control. The achievements of cartographers and geographers underlie the successful military presence of Russian ships in the World Ocean and the movement of civilian, transport and fishing vessels. A holiday has been established in honor of professionals involved in scientific research of coastal and open waters, metrology and topography, and navigation support for maritime activities. October 13 is the Day of the Hydrographic Service of the Russian Navy. Military personnel and scientists are engaged in research work in sea and ocean waters on ships specially built for this purpose. The service has more than 150 pilot and hydrographic vessels and boats at its disposal. Their number is constantly increasing due to the launching of new ships. According to the International Hydrographic Organization, the level of knowledge of the waters of the World Ocean is no more than 22%. Therefore, professional activity in this direction will be as relevant in the coming years as it was 200-300 years ago. Hydrographic Service Day was established as a result of the release in January 1997 of Order No. 15 of the Commander-in-Chief of the Navy. The date of the holiday coincides with the creation of the Office of the General Cartographer back in 1827. The second name of the celebration is the Day of the Military Sailor-Hydrographer. On this occasion, conferences, concerts, and events to award veterans with certificates and memorable awards are organized. Active military personnel and civilian personnel are also congratulated on the holiday, wishing them successful sea voyages to the near and far oceanic zones, new scientific discoveries for the benefit of the Motherland.
