There are 24 seasonal points annually.

12 of which marks the commencement of each solar month (jie), with the remaining 12 marking the mid-months (qi). Which leads to the name 24 jie qi (二十四节气).

For example, the first day of the first month begins on li chun (立春), with it’s mid-month on yu shui (雨水).
