May 20: holidays and events on this day
May 20 is celebrated as the Day of Bank Employees of Ukraine, the Day of Sign Language Interpreter in Ukraine, as well as World Traumatologist Day, World Metrology Day and World Bee Day. This day in history is associated with events that influenced the development of religion, navigation, science, education, aviation, culture, sports and politics in different countries of the world.
Day of Bank Employees of Ukraine
Today, we honor banking workers, whose work determines the stability of the country’s financial system. The holiday was introduced in 2004 to honor specialists who ensure the operation of state and commercial banks, make settlements, control financial transactions, serve customers and support the functioning of the economy. The banking system includes thousands of employees – from cashiers and managers to analysts, security specialists and international payments. Currently, the banking sector of Ukraine is one of the most digitalized in Europe, and most financial transactions are carried out online.
After the start of a full-scale war, bank employees continued to work even in frontline cities and during massive shelling. Ukrainian banks were able to quickly restore services after cyberattacks, ensuring uninterrupted operation of ATMs, online banking and transfers, and helping people receive payments, pensions and humanitarian aid. Some employees worked in branches without electricity and communications, using backup power systems and satellite Internet.
Interesting facts
Ukrainian banking has a long history that developed along with trade and industry. In the 19th century, land, city and merchant banks operated on the territory of Ukraine, serving entrepreneurs, artisans and landowners.
At different times, bank employees worked with paper ledgers, manually counted large sums of money, checked the authenticity of banknotes and kept documentation without modern technology.
The first city bank in Kyiv was opened back in 1868. Its employees kept all accounts manually in large journals, and documents were stored in special fireproof rooms.
In the banks of Odessa in the 19th century, employees often knew several languages, because the city had active international trade. Employees communicated with customers in Ukrainian, Russian, French, Greek and Italian.
At the beginning of the 20th century, Ukrainian banks had separate employees who checked the authenticity of banknotes all day long by touch, by watermarks and by the smell of paint.
During the Soviet period, employees of savings banks in Ukraine filled out savings books by hand, and records of money deposits were often made with special ink pens that did not fade for decades.
In 1991, after the declaration of independence of Ukraine, the banking system actually had to be created anew, because the country was transitioning from the Soviet financial model to its own.
The first Ukrainian ATMs appeared in the mid-1990s, and many people were initially afraid to use them, thinking that the card might be “taken away by the machine.”
In 1996, during the introduction of the hryvnia, Ukrainian bank employees worked almost 24 hours a day, exchanging coupon-karbovanets for the new currency and transferring huge amounts of cash.
Sign Language Interpreter Day in Ukraine
This is a professional holiday for professionals who help people with hearing impairments communicate, receive information, learn, and use government services. It was launched by the Ukrainian Society of the Deaf in 2009 to draw attention to the importance of this profession and the needs of people for whom sign language is the main means of communication.
Sign language interpreters work in educational institutions, courts, hospitals, government agencies, on television, and during official addresses. They do not simply translate words with gestures, but convey the content, emotions and intonation of speech, because sign language has its own grammar and peculiarities. The need for such specialists is gradually growing in Ukraine, as the accessibility of information for people with hearing impairments is becoming an important part of social life.
Interesting facts
Ukrainian sign language is not universal for all countries. It has its own vocabulary and grammar, so people with hearing impairments from Ukraine cannot always easily communicate with speakers of other sign languages using gestures.
In the 19th century, schools for children with hearing impairments in Ukraine often banned the use of gestures, believing that students should be taught only oral speech.
The first sign language interpreters in Ukraine were often relatives of people with hearing impairments, who independently learned gestures for everyday communication.
Sign language interpretation began to appear actively on Ukrainian television after gaining independence, and at first such broadcasts were broadcast only in individual news programs.
Sign language has its own ways of conveying emotions, and facial expressions, head position, and body movements are of great importance, without which part of the content can be lost.
For a long time, the profession of a sign language interpreter in Ukraine remained inconspicuous, although it was these specialists who helped people with hearing impairments to get an education, get a job, and interact with government institutions.
Some sign language interpreters can simultaneously translate very fast speech live, almost without delay, which requires high concentration and special training.
World Traumatologist Day
This is a professional holiday for doctors who treat injuries, fractures, dislocations, joint injuries, and the consequences of severe physical injuries. Traumatologists work in hospitals, trauma centers, operating rooms and rehabilitation centers, helping patients after accidents, sports injuries, falls and disasters. Their profession combines surgery, orthopedics and emergency medicine, and the speed of decisions often determines whether a person will be able to fully move after an injury.
Traumatology began to develop actively in the 19th century after the spread of industrial production and an increase in the number of complex injuries. Wars had a great influence on the development of this field, during which doctors had to quickly improve methods of treating fractures and wounds. Modern traumatologists use titanium implants, microsurgery, arthroscopy and computer diagnostics, although a hundred years ago many fractures were treated without X-rays, and patients lay motionless for months for the bones to grow together.
Interesting facts
In ancient Egypt, doctors already knew how to apply splints to broken limbs. Archaeologists have found mummies with traces of correctly fused fractures.
The first X-ray of a fracture was taken at the end of the 19th century, almost immediately after the discovery of X-rays, and this radically changed the work of traumatologists.
In the Middle Ages, many fractures were treated by barbers, not doctors. They adjusted the bones, applied bandages, and even performed amputations.
Before the advent of anesthesia, several people held patients during complex operations, because any intervention was accompanied by severe pain.
During the First World War, traumatologists began to massively use metal structures to fix bones, since the number of serious injuries was huge.
The well-known method of pulling a broken limb with weights was used for decades, and some patients were kept in this position for several months.
In the 20th century, traumatologists learned how to sew severed fingers and limbs together thanks to the development of microsurgery and working with small vessels under a microscope.
Modern titanium implants are so strong that they can sometimes withstand loads better than human bone.
World Metrology Day
This is a professional holiday for specialists involved in measurements, instrument accuracy and standard control in science, medicine, industry and trade. The event was initiated by the International Committee for Weights and Measures in 1999 to commemorate the signing of the Metric Convention of 1875, which became the basis of a single international measurement system. Metrologists are responsible for the accuracy of scales, thermometers, meters, laboratory equipment and many other devices that people use every day.
Metrology is of great importance for the modern world, because without accurate measurements, the production of equipment, construction, medicine, aviation and scientific research are impossible. Errors even in fractions of a millimeter or gram can lead to serious consequences in pharmaceuticals, the space industry or energy. Modern metrologists work with ultra-precise standards of time, mass, temperature, and length, and the development of digital technology has made measurements much more complex and accurate than in previous centuries.
Interesting facts
In France, after the revolution at the end of the 18th century, the meter and kilogram were created as universal units of measurement so that different regions of the country would no longer use hundreds of different measures.
The first international standard of the kilogram was stored in France for over a hundred years under several glass caps in a special safe.
Before the introduction of uniform standards, the same unit of weight or length could differ significantly in different countries, which led to trade disputes and errors.
In medieval cities, sellers could be punished for incorrect weights, and in the markets there were special people who checked the accuracy of measures and weights.
The name “meter” comes from the Greek word “measure”, and it was originally defined as part of the length of the Earth’s meridian.
A second in the modern world is not determined by the movement of the Sun, but by the oscillations of cesium atoms in an atomic clock.
Due to ultra-precise measurements, modern GPS navigators even take into account the influence of Einstein’s theory of relativity, otherwise the error in coordinates would quickly increase by several kilometers.
In the 19th century, some factories specially forged weights for scales in order to make more profit when trading goods.
The first thermometers did not have a single scale, so the readings of one device could differ significantly from another even at the same temperature.
World Bee Day
This is an environmental holiday initiated by the United Nations in 2017 to draw attention to the importance of bees and other pollinators in nature and agriculture. The date was chosen in honor of the birthday of Slovenian beekeeper Anton Janša, who is considered one of the founders of modern beekeeping. Bees play a key role in pollination, which is essential for the growth of many vegetables, fruits, berries, and grains.
In recent decades, the world has seen a massive decline in bee populations due to pesticides, climate change, disease, and habitat destruction. Scientists believe that without pollinators, many plants would not be able to reproduce properly, and the yields of many crops would plummet. Beekeeping has been around for thousands of years, and honey, beeswax, and propolis have been used not only as food, but also in medicine, trade, and religious ceremonies throughout history.
Interesting Facts
Bees appeared on Earth about 100 million years ago and have lived since the time of dinosaurs.
To produce one kilogram of honey, bees need to visit several million flowers and fly a total distance equivalent to several orbits around the Earth.
In ancient Egypt, honey was considered so valuable that it was sometimes used to pay taxes and as a gift to rulers.
Bees can communicate with each other about the location of flowers by performing a special “dance” that shows the direction and distance to the nectar source.
In the Middle Ages, beeswax was one of the most valuable commodities in Europe, as it was used to make church candles.
A single worker bee produces only about a teaspoon of honey in its lifetime.
A queen bee can lay up to two thousand eggs a day during the colony’s peak activity.
Archaeologists have found jars of honey in ancient tombs, and even after thousands of years, it has remained edible.
Bees have five eyes: two large compound eyes and three small eyes located on top of the head.
