Today - February, 29. Every four years, the calendar does not contain 365 days, but 366. That's why 2020 is called a leap year. The term "fragile" is thought to come from the ancient Romans. They thought the leap year was followed by epidemics and diseases. But it is simply unfounded thinking.

What if we don't add one day every four years?

The earth rotates around the sun for 365 days and six hours, meaning it has an extra day every four years. Unless we add one extra day, then centuries later, people can go shopping for Christmas in June.

This change in calendar came to Rome and then to the Western world by the Egyptians, who along with the Maya and Babylonian tribes were among the first to accurately determine the Earth's rotation around the Sun.

In fact, the 6 "extra" hours each year are actually 5 hours, 48 minutes and 46 seconds. So Pope Gregory XIII, convinced that the holidays were being celebrated in error, proposed in 1582 his calendar, which does not add a single day to the years that correspond to 100 but not 400. So 2000 was a fragile year, but 1700, 1800 and 1900 no. Not even 2100 will be. The Gregorian calendar is the most widespread calendar in the world today.

The leap year is known as the "leap year" or "leap year" because it misses two days with the dates listed. For example, in 2018, Christmas shot on Tuesday, 2019 on Wednesday, while this year will be on Friday, while if it were not the leap year, it would be on Thursday.

What are the chances of being born on February 29 (like Capital T for example)? According to studies, the odds of being born on February 29 are 1 in 1461. Those born on this date usually celebrate their birthday on March 1 because no one wants gifts just every four years.
