《月令七十二候集解》：「十一月節，大者盛也，至此而雪盛矣。」大雪，二十四節氣之一，每年在12月6-8日之間，太陽位於黃經255°，北方地區會受冷空氣影響，常出現較大的降雪，引起地面積雪.

The traditional East Asian calendars divide a year into 24 solar terms (節氣). Dàxuě (pīnyīn) or Taisetsu (rōmaji) (Chinese and Japanese: 大雪; Korean: 대설; Vietnamese: Đại tuyết; literally: "major snow") is the 21st solar term. It begins when the Sun reaches the celestial longitude of 255° and ends when it reaches the longitude of 270°. It more often refers in particular to the day when the Sun is exactly at the celestial longitude of 255°. In the Gregorian calendar, it usually begins around 7 December and ends around 21 December (22 December East Asia time).
