The traditional Chinese lunisolar calendar divide a year into 24 solar terms.^[1] Gǔyǔ is the 6th solar term. It begins when the Sun reaches the celestial longitude of 30° and ends when it reaches the longitude of 45°. It more often refers in particular to the day when the Sun is exactly at the celestial longitude of 30°. In the Gregorian calendar, it usually begins around April 20 and ends around May 5.

Pentads

Each solar term can be divided into 3 pentads (候). They are: first pentad (初候), second pentad (次候) and last pentad (末候). Pentads in Guyu include:

Second pentad: 鳴鳩拂其羽, 'Cuckoo shakes off wings'.^[2]
Last pentad: 戴勝降于桑, 'Hoopoe perches in mulberry trees'.^[2]
