Shuangjiang (solar term) (original) (raw)

The traditional Chinese lunisolar calendar divides a year into 24 solar terms (节气/節氣). Shuāngjiàng (Chinese: 霜降; pinyin: shuāngjiàng) is the 18th solar term. It begins when the Sun reaches the celestial longitude of 210° and ends when it reaches the longitude of 225°. It more often refers in particular to the day when the Sun is exactly at the celestial longitude of 210°. In the Gregorian calendar, it usually begins around October 23 and ends around November 7. The western holiday of Halloween occurs in this solar term.
