The structure of the calendar depends on the exact times of certain astronomical events, principally dark moons and winter solstices.
The solar calendar consists of a series of seasonal years which are divided into 24 "solar terms". The lunar calendar consists of a series of years which are divided into 12 or 13 lunar months.
A solar year always begins at the (northern) winter solstice. A lunar month always begins on the day of a dark moon.
