What year is leap August? When is the next time?

The occurrence time of leap August is not fixed, and the next time is in 2052.

Leap August is a leap month with medium frequency, which is second only to leap April, leap June and leap July. Generally, it occurs once every 19 years (such as 1957 and 1976), and sometimes it occurs once every 8 years (such as 2454 and 2462) or 165438.

When there is an interval of 38 years (such as 1680, 17 18) or a multiple of 19 (such as 2845,2921year, with an interval of 76 years, 76 is/kloc-0). Another example is 2462 and 2557, the difference is 95 years, 95 is 5 times of 19), and one is greater than 19, but the difference is not more than 38 years (for example, 2796 and 2826, the difference is 30 years).

What's more, it is 100 years or more (for example, 17 18, 185 1 year, 133 is 19).

The origin of leap month:

The lunar leap month is to coordinate the contradiction between the tropic year and the lunar year.

The total length of the tropic year is 365.2422 days, and the length of the first lunar month is 29.5306 days. 12 lunar months make up the lunar year, with a length of 29.5306× 12=354.3672 days, which is 10.88 days less than the regression, and about1/kloc-0 per month less than 0.9 1 day.

Accordingly, if the Spring Festival in one year of the lunar calendar is a snowy winter, the Spring Festival in the next year will be 1 1 day earlier than the season, and 16 Lunar New Year will appear in the hot summer.

If the lunar year consists of thirteen lunar months, the length is 29.5306× 13=383.8978 days, which is more than the tropic year 18 days.

If the calendar is made according to the above regulations, there will be a strange phenomenon that the weather is inconsistent with the calendar and the time order is disordered and reversed-this is contradiction.

In order to overcome this shortcoming, on the basis of astronomical observation, the method of "leap month" is found out, which ensures that the first month to March is spring, April to June is summer, July to September is autumn, and October to December is winter. At the same time, it also ensures that the first year of the lunar calendar is in late winter and early spring.
