## Video: What Years Are Called Leap Years

The leap year was calculated and introduced during the reign of Tsar Julius Caesar. It was on his behalf that astronomers discovered the inaccuracy of the previous calculations of the time of the Earth's revolution around the Sun and compiled a new calendar, in which a leap day, February 29, appears every four years.

## Instructions

### Step 1

A year is a time period during which the Earth makes a complete revolution around the Sun's orbit. This time lasts 365 days, 5 hours, 48 ​​minutes and about 46 seconds. Hours, minutes and seconds add up to about a quarter of a day. Therefore, for convenience and to compensate for the temporary difference, an additional day of February 29 was introduced every four years.

### Step 2

A year is a leap year if the sum of its digits is divisible by 4 but not divisible by 100. And also if all digits of the year are summed to be divisible by 4, 100 and 400.

Examples of leap years: 1908, 1936, 1996, 2000, 2060, 2400.

### Step 3

There are 12 symbolic animals in the Eastern calendar, each of which is the patron saint of its own year. Rat, Dragon and Monkey are always symbols of a leap year, as they alternate with each other every four years. These animals are considered especially important in the Eastern calendar.

### Step 4

Many fears and warnings refer to a leap year, various signs and superstitions. It is believed that in a leap year there is no need to start a new business, get married or get married. These popular discussions are often exaggerated, but not without foundation.

According to astrological calculations, leap years coincide with peaks of extremely high and extremely low solar activity. This is a consequence of the tectonic activity of the planet, which leads to earthquakes, volcanic eruptions, crop failures and climatic disruptions. As a result, there are political crises and unrest.

### Step 5

In the historical chronicle, there are many different military and political events that fall on leap years. But according to research by scientists who conducted a comparative analysis, such things have happened at all times, regardless of the presence of a leap day in the year.

### Step 6

Various myths and legends also describe the mysterious and disturbing events of leap years. One of these legends mentions the stingy, envious and vindictive Kasian, who was born on February 29th. Once the poor man asked Kasyan and Nikola for help - to pull out the goats stuck in the mud of the off-road. Kasyan refused for fear of getting his heavenly clothes dirty, and Nikola agreed. After this incident, Kasyan was punished by God, and he was forbidden to hold a prayer service for three years, only in the fourth leap year he could perform this significant ceremony. Nicola, for his pious deed, was allowed to hold a prayer service twice a year.
