How long is each of the 24 solar terms in a year?

As a festival of the lunar calendar, the 24 solar terms are completely related to the sun, not to the "month" of the lunar calendar, so these solar terms have a relatively fixed time in the solar calendar (there is no difference of one or two days before and after, for example, Tomb-Sweeping Day usually has two solar terms every month, with a difference of 15 days). The approximate solar terms are as follows:

The spring rain shocks the clear sky in the spring valley, and the summer is full and hot. Autumn dew, autumn cold and frost, and winter snow.

Namely, beginning of spring, Rain, Creeping, Equinox, Grain Rain, Qingming, Long Summer, Xiaoman, Busy, Summer Solstice, Slight Summer and Great Summer.

Beginning of autumn, first summer heat, white dew, autumnal equinox, cold dew, first frost, beginning of winter, light snow, heavy snow, winter solstice, slight cold and severe cold.
