The traditional chinese calendar divides a year into 24 solar terms.[1]
Yǔshuǐ / 雨水, Usui, Usu, or Vũ thủy, literally meaning rain water, is the second solar term.
It begins when the Sun reaches the celestial longitude of 330° and ends when it reaches the longitude of 345°. It more often refers in particular to the day when the Sun is exactly at the celestial longitude of 330°.
In the gregorian calendar, it usually begins around 18 February (19 February of / in east Asia time) and ends around 5 March.
Pentads
[edit]Each solar term can be divided into three pentads (候), first (初候), second (次候) and last (末候) ones.
In Yushui each pentad includes :
- in China,
- first pentad / 獺祭魚 : 'otters make offerings of fish'. As fish begin to swim upstream, they are hunted by otters, which are believed to offer the fish to heaven ;
- second pentad / 鴻雁來 : 'the wild geese arrive'. Wild geese begin to make their northward migration, following the onset of spring ;
- last pentad / 草木萌動 : 'trees and grass put forth shoots' ;
- in Japan,
- first pentad / 土脉潤起 ;
- second pentad / 霞始靆 ;
- last pentad / 草木萠動.
