The traditional Chinese lunisolar calendar divides a year into 24 solar terms (節氣).
Xiǎoxuě (Chinese: 小雪; pinyin: xiǎoxuě) is the 20th solar term.
[1] It begins when the Sun reaches the celestial longitude of 240° and ends when it reaches the longitude of 255°.
It more often refers in particular to the day when the Sun is exactly at the celestial longitude of 240°.
In the Gregorian calendar, it usually begins around 22 November and ends around 7 December.
