Hello, since the founding of the People's Republic of China, the Ministry of Education has set the start time of each spring at 1 in March, with a maximum difference of one or two days. There are two main reasons:

First, as the saying goes, "A year's plan lies in spring". In March, spring warms the earth and everything recovers. No matter in the north or the south, this is the best time to start school.

Second: China solar calendar in February, corresponding to the first lunar month, which has many traditional festivals. Considering our traditional customs, it is in line with the actual situation in our country to stagger February and choose March 1 day to start school.

Secondly, the Ministry of Education has set the date of beginning of autumn as September 1, mainly because from mid-July to the end of August, China is in the hottest dog days in summer, so it is more in line with the actual situation in China to avoid the dog days and choose September with crisp autumn.
