2020, a fragile year: How was the calendar born 366 days?

Every four years, the calendar contains, not 365 days, but 366. One such year, where February is 29 days, is called a fragile year. The term is thought to come from the ancient Romans. They felt that the fragile year was followed by epidemics and disease. But it's just an empty thought.

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

The earth orbits the sun for 365 days and six hours, meaning that it has an extra day every four years. If we don't add an extra day, then centuries later, people can shop at Christmas in June.

This shift in the calendar came to Rome and then to the Western world by the Egyptians, who, along with the Maya and the Babylonians, were among the first to accurately determine earth's orbit around the sun.

In fact, 6 hours “te for” each year are actually 5 hours, 48 minutes and 46 seconds. So Pope Gregory X III, convinced that the holidays were being celebrated incorrectly, proposed his calendar in 1582, which does not add much to the 100 - year - long years but not to 400. So the year 2000 was a fragile year, but 1700, 1800, and 1900 did not. Not even 2100 will be. The Gregorian calendar is the most popular calendar in the world today.

The brittle year is known as <x0) For example, in 2018, Christmas shot on Tuesday, this year on Wednesday, and in 2020 it would be on Friday, while if it wasn't a fragile year, it would be Thursday.

What are the chances of giving birth on February 29th? According to studies, the chances of giving birth on February 29th are 1 in 1461. Those born on this date usually celebrate their birthday on March 1st, because no one wants presents just every four years.
