Those months belong to spring.

January, February and March are spring.

In China, there are different standards for the division of the four seasons. In astronomy, the vernal equinox, summer solstice, autumn equinox and winter solstice are the beginning of spring, summer, autumn and winter respectively.

Folk customs take the summer calendar as the spring of February and March, the summer of April, May and June, the autumn of July and August, and the winter of November and December.

Statistically, because it is generally the coldest month in 1 year and July is the hottest month in the solar calendar, March, April and May are spring months, June, July and August are summer months, and September 10,1are autumn months, and the following year1. This method of dividing the four seasons is more in line with temperate regions with distinct seasons.

Extended data:

The first of the four seasons refers to the period from beginning of spring to Long Summer, including solar terms such as beginning of spring, rain, fright, vernal equinox, Qingming and Grain Rain. This is the season when everything comes back to life.

In meteorology, the beginning of spring is that the average temperature is above 10℃ for five consecutive days. In spring, the climate is warm and mild, and there is rain in most inland areas of China, where everything germinates and the climate is changeable.

Standing is the beginning, and beginning of spring is beginning of spring. Since the Qin Dynasty, beginning of spring has been the beginning of spring in China. Beginning of spring is divided from astronomy, but in nature and people's minds, spring is warm and flowers are fragrant. Spring is growth, cultivation and sowing. In climatology, spring refers to the period when the average temperature is between 10℃ and 22℃.

Speaking of beginning of spring, people obviously feel that the days are getting longer and the sun is getting warmer. Temperature, sunshine and rainfall are often at the turning point of the year and tend to rise or increase. The growth of crops in early spring is accelerated, and the water consumption for bolting rape and jointing wheat is increased. Irrigation and topdressing should be done in time to promote growth.
