Tomb-Sweeping Day is a traditional festival. Why do you use the solar calendar?

This is the lunar calendar, actually it is the lunar calendar. There are no twenty-four solar terms in the solar calendar.

Because both the lunar calendar and the solar calendar are calendars, although the solar calendar is more accurate than the lunar calendar, there is always a fixed difference of several days, so their dates are relatively fixed in the Gregorian calendar. The first half of the solar term is 6 days, the second half is 8 days, and the second half is 23 days, with a difference of 1 ~ 2 days.

Tomb-Sweeping Day, also known as the outing festival, according to the solar calendar, between April 4th and 6th every year, it is the season of beautiful spring and lush vegetation, and it is also a good time for people to have a spring outing (called outing in ancient times), so the ancients had the custom of going for an outing in Qingming and carrying out a series of sports activities. Tomb-Sweeping Day, also known as the March Festival in ancient times, has a history of more than 2,000 years.

Tomb-Sweeping Day is one of the 24 solar terms around April 5th in the Gregorian calendar. Among the 24 solar terms, Qingming is the only solar term that is both a solar term and a festival. In ancient China, the Qingming Festival was divided into three stages: "One stage was when tung flowers began to bloom; Second, the vole became a quail; I'll see you when I wait for the rainbow. " That is to say, at this time, the white paulownia blooms first, then the happy voles in the shade disappear and all return to the underground caves, and then the rainbow can be seen in the sky after the rain.
