4, 24, 72 Seasons

There is a tradition of dividing the year into 24 solar terms and 72 pentads in the East Asian cultural sphere. This way, each of the four classical seasons can be partitioned into six solar terms, each of which can be divided into three pentads which last around five days each. This calendar displays the current season, solar term and pentad and a fitting, illustrative for each.

The seasons can be browsed by clicking on the buttons below.

Inspired by the great app 72 Seasons.
