Nineteenth solar term of traditional East Asian calendars
The traditional Chinese calendar divides a year into 24 solar terms. Lìdōng, Rittō, Ipdong, or Lập đông (Chinese and Japanese: 立冬; pinyin: lìdōng; rōmaji: rittō; Korean: 입동; romaja: ipdong; Vietnamese: lập đông; "start of winter") is the 19th solar term. It begins when the Sun reaches the celestial longitude of 225° and ends when it reaches the longitude of 240°. It more often refers in particular to the day when the Sun is exactly at the celestial longitude of 225°. In the Gregorian calendar, it usually begins around November 7 and ends around November 22.[1]
Lidong signifies the beginning of winter in East Asian cultures.[2]
