Farmers' busiest solar terms in a year

Mangzhong, the ninth of the 24 solar terms.

On June 5 or 6 of the Gregorian calendar every year, when the sun reaches 75 degrees of the yellow meridian, it is an awn. In North China, there is a saying that "the wheat is covered first in April and then in May", which is caused by the lunar calendar algorithm. According to the lunar calendar, a year is actually 344-345 days.

This is less than the number of days to serve around the obstacle 10- 1 1 day, so it needs to jump every three years (sometimes two years) to make up for the shortage of days. Between months, solar terms are either advanced or postponed, so sometimes in April and sometimes in May.

Farmers in China know very well that crops should be planted early, because spring begins in early April and the solar terms are advanced. They should be planted before the crops are planted in May and after the solar term.
