In 2020, there will be a "leap April" in China Lunar Year of the Rat, with a total of 384 days.

Extended data:

Gregorian leap year:

The period of the earth's orbit around the sun is 365 days, 5 hours, 48 minutes and 46 seconds (365.438+09 days), which is the tropic of cancer. The average year of the solar calendar is only 365 days, which is about 0.2422 days shorter than the tropical year and accumulates one day every four years. Add this day to the end of February (that is, February 29th), and the duration of the current year will become 366 days (1- 12 months are 3 1 day, 29 days and 365438+ respectively).

It should be noted that the Gregorian calendar was adapted from the Roman "julian calendar". Because we didn't realize the problem of calculating 0.0078 extra days every year, from 46 BC to16th century, there were 10 extra days in total. Therefore, Pope Gregory XIII at that time set the artificial date of 65,438+0,582,65,438+0.05 as 65,438+0.00,65,438+0.05.

And began to implement the new leap year regulations. That is to say, it is stipulated that the Gregorian calendar year is an integer hundred, the leap year must be a multiple of 400, and the average year is not a multiple of 400. For example, 1700 and 1800 are normal years, and 2000 is a leap year. Since then, the average annual length is 365.2425 days, and the deviation of about 4 years is 1 day.

According to a leap year every four years, the average annual increase will be 0.0078 days, and it will increase by about 3 days after 400 years. Therefore, three leap years will be reduced every 400 years. The calculation of leap year can be summed up as what is commonly said: leap every four years; Never leap in a hundred years, and then leap in four hundred years.

Leap year from 1950 to 2050:

1952、 1956、 1960、 1964、 1968、 1972、 1976、 1980、 1984、 1988、 1992、 / kloc-0/996、2000、2004、2008、 20 12、20 16、2020、2024、2028、2032、2036、2040、2044、2048。
