When is the first frost in 2022 and when is the first frost tomorrow?

Frost time at the beginning of 2022: 65438+1October 23rd 18:35:3 1, Sunday, September 28th of the lunar calendar. "First frost" refers to a sudden drop in temperature and a large temperature difference between day and night. On the national average, "first frost" is the season with the largest temperature difference between day and night in a year.

The ancients in China divided the fifteen days of the first frost season into three periods: the first period was when jackals sacrificed animals; Second, the vegetation is yellow; Three stings are salty.

A waiting jackal is a sacrifice to wild animals, which means that in this solar term, jackals begin to catch prey, sacrifice what they have caught first to wild animals, and sacrifice wild animals to heaven in return. Like the harvest of the new valley on the earth, it is used to worship the sky to show the return and pray for good weather in the coming year.

Second, the vegetation is yellow, paraquat is exhausted in autumn, and butterflies are flying in the frost. In autumn, the west wind is rolling and the leaves are yellow.

At this time, the stinging insects are motionless in the hole and droop their heads into hibernation.

At this time, nature is a silent beauty. Bees and butterflies are gone, and the stinger is silent. They are all preparing for the long winter.
