April 1 is celebrated as April Fool’s Day, International Day of Fun at Work, International Bird Day (Ornithologist’s Day), International Frivolite Day and Dollar Birthday. The events of this day cover government decisions, scientific inventions and military conflicts that have influenced the development of countries and societies in different years.
April Fool’s Day
This is an unofficial but popular holiday associated with jokes, pranks and light irony. Its origin is not fully understood, but there are versions that the tradition arose in Europe after the transition to the Gregorian calendar, when some people continued to celebrate the New Year in the spring and became the object of jokes. Over time, the custom spread to different countries and acquired local characteristics, but the common feature remained the desire to joke without harming others.
In the modern world, this day is used as an opportunity to relieve stress, switch from everyday affairs and look at things with humor. The media, companies and ordinary people often invent fictional news or funny situations that are revealed at the end of the day. In Ukraine, the tradition has also taken root, although it is usually limited to friendly jokes among acquaintances, colleagues or family.

In 1957, the BBC broadcast a story about the “spaghetti harvest” in Switzerland, and many viewers believed that pasta grows on trees.
In Ukraine, there were references to April Fools’ Day jokes in cities as early as the 19th century, particularly in Lviv and Odessa, where they were actively supported by the urban culture of humor.

In Japan, April Fools’ Day does not have deep traditions, but in recent decades it has been actively popularized by international companies and brands.
In ancient times, in some countries, it was believed that the first person to joke on April 1 would have good luck throughout the year.
International Day of Fun at Work
This is an unofficial holiday, launched in 1996 as an initiative to draw attention to the atmosphere in work teams. The idea is that friendly humor and informal communication can positively affect the productivity and psychological state of employees. On this day, various companies allow more freedom in communication, organize light pranks or unusual activities without harming the work process.
The holiday has spread thanks to corporate culture, especially in the office environment. It is supported as a way to reduce stress and prevent professional burnout. In Ukraine, such initiatives are more common in international companies and creative industries, where informal communication and team interaction are encouraged.
Interesting facts

Small pranks with technology are popular in Ukrainian offices, such as changing the interface language or wallpaper on a colleague’s computer.
Psychologists note that shared humor in the team can improve trust between employees faster than formal team-building activities.
International Bird Day (Ornithologist’s Day)
This is an environmental holiday dedicated to the protection of birds and drawing attention to the preservation of their natural habitats. It was founded at the end of the 19th century after the conclusion of an international agreement on the protection of species useful for agriculture. The date was chosen not by chance, since it is in early April that migratory birds return to many regions, symbolizing the restoration of natural cycles.
This day is also considered a professional holiday for ornithologists — specialists who study birds, their behavior, migration, and role in ecosystems. In Ukraine, birds are important for biodiversity, and researching their populations helps assess the state of the environment. In modern conditions, special attention is paid to the preservation of nesting sites and migration routes, which are often disturbed by human activity.
Interesting facts
There are over 400 species of birds in Ukraine, and a significant part of them are migratory, covering thousands of kilometers between seasons.
The largest bird in Europe, the bustard, also lives in Ukraine, but due to the reduction of steppes, its number has sharply decreased.
Storks, which are a symbol of Ukrainian villages, return to almost the same nests every year, sometimes using them for decades.
The peregrine falcon is considered the fastest bird in the world — during a dive, it can reach speeds of over 300 km/h.
In Kyiv and other major cities of Ukraine, the population of falcons and hawks, which have adapted to life in an urban environment, is gradually growing.
Some birds are able to navigate the Earth’s magnetic field, which helps them during long flights.
The smallest bird in Europe is the kingfisher, its weight is only a few grams, but it can withstand cold winters.
In Ukraine, there are special ringing stations where birds are given light tags to track their migrations.
Crows demonstrate a high level of intelligence, can use objects as tools and remember people’s faces.
International Tatting Day
This is an unofficial holiday dedicated to the technique of creating lace using knots and loops. Tatting is one of the types of decorative and applied arts that originated in Europe several centuries ago and was used to decorate clothes, accessories and interior items. The main tool is a shuttle or needle, with which characteristic patterns of rings and arcs are formed.
This craft has remained popular among hand-made masters, despite the development of machine-made lace production. Different countries have their own traditions and styles of execution, and modern masters combine classic techniques with new materials and designs. In Ukraine, frivolity is not a mass type of needlework, but it has its own community of fans who restore old patterns and create original products.
Interesting facts
The name “frivolity” comes from the French word meaning “frivolous”, but in the context of the craft it indicates the elegance and lightness of the lace.
In the 19th century, frivolity was popular among the aristocracy, and women often carried shuttles with them as an accessory.
There are shuttles with built-in spools and even with a hook at the end, which allows you to combine different techniques in one product.
One of the thinnest materials for tatting is silk thread, from which almost weightless jewelry is created.
Some museums in Europe keep tatting lace that is over 150 years old, and they remain well preserved.
In Ukraine, this technique is sometimes used to create elements of modern jewelry, in particular earrings and pendants.
Tatting can be performed not only by hand, but also with the help of special needles, which makes the technique more accessible to beginners.
Some craftsmen create complex compositions from dozens of individual elements that are connected into a single pattern.
Unlike most types of lace, tatting does not use knitting needles or a hook as the main tool.
Birthday of the Dollar
April 1 is associated with the appearance of the dollar symbol, since in 1778 the merchant Oliver Pollock used the “$” sign in financial records. It is believed that he created it based on the abbreviation of the Spanish currency peso, which was denoted as “PS”. Over time, the symbol simplified to the familiar form with a vertical line crossing the letter S, and began to be widely used in documents and trade.
The dollar as a currency officially appeared later – in 1792, after the adoption of the Coinage Act in the United States. Since then, it has become one of the key currencies of the world, and its symbol has acquired global significance. Today, the dollar sign is used not only for American currency, but also to denote money in a broader sense, especially in economic and financial contexts.
Interesting facts
The symbol “$” existed before the official introduction of the dollar and was used to denote the Spanish peso in North America.
One version of the origin of the sign connects it with a stylized image of the Pillars of Hercules with a ribbon, which were on Spanish coins.
The first dollar bills did not have a single design, and different banks issued their own versions of the notes.
The largest bill ever printed in the United States was $100,000, but it was used only for internal settlements between banks.
In the 19th century, the word “dollar” was used for different currencies in different countries, not just the American one.
In Ukraine, the dollar has long remained one of the main foreign currencies for savings of the population, especially during periods of economic instability.
The dollar sign is sometimes written with two vertical lines, although in modern use the option with one is more common.
The dollar is one of the most common reserve currencies in the world, and a significant part of international settlements is carried out in it.
The word “dollar” comes from the “thaler” – a silver coin that was used in Europe as early as the 16th century.
