What is the beginning of 20 12 spring time? What month is the solar calendar?
Astronomical experts said that at present, there are two kinds of calendars commonly used in China, namely Gregorian calendar (solar calendar) and lunar calendar.
The solar calendar has 365 days in a normal year and 366 days in a leap year. The lunar calendar has 354 days in a normal year and 383 days in a leap year.

The ancient "Li Si" refers to the beginning of spring, summer, autumn and winter, and its agricultural meaning is "planting in spring, growing in summer, harvesting in autumn and storing in winter", which summarizes the whole process of the relationship between agricultural production and climate in the middle and lower reaches of the Yellow River.
