Grain Rain solar terms in May.

In the lunar year, each earthly branch corresponds to 24 solar terms from one solar term (non-neutral) to the next, and the initial one-month cycle is determined by the node time, not from the first day to the end of a certain lunar month. Many almanac shows that a lunar month corresponds to a branch, which is only approximate but not complete. In case of a or one's own year, the first month is roughly C Yin; B or Geng Year, the first month is roughly Wuyin; The first month of year C or Xin is roughly Geng Yin, the first month of Ding Nian or Ren Year is roughly Ren Yin, and the first month of year E or decyl is roughly Jia Yin. The first month is calculated according to the main branch, and other months are calculated according to the main branch. A cycle of 60 months and 5 years; Reuse after a cycle, cycle after cycle, cycle. In the 29th year of Jianwu (A.D. 53), the month from winter to the sun and the moon (the month from heavy snow to slight cold, similar to November of the lunar calendar) is the "Jiaziyue". The following table shows the corresponding solar cycle, neutral gas, approximate lunar month, approximate solar month, and monthly stem composed of annual stem and lunar branch: in the solar cycle of lunar branch, gas is approximate lunar month, approximate solar month A or year B or Geng year C or Xin Ding year or nonnian year E or decyl.
