Lidong signals start of winter season in Chinese solar calendar
Occurring annually between November 7 and 8, Lidong marks the 19th of the 24 traditional Chinese solar terms and the beginning of the winter season.
Astronomically, Lidong is defined by the sun reaching a celestial longitude of 225 degrees. While this date traditionally signals the onset of winter, the actual meteorological cooling is often delayed as the earth releases heat accumulated during the previous months. Consequently, significant temperature drops frequently follow the date by approximately three weeks.
Historically rooted in agricultural society, the period served as a time for harvest festivals and rituals to honor ancestors. Cultural practices vary significantly by geography, with northern regions traditionally marking the date by consuming dumplings, while southern areas emphasize energy-dense foods such as poultry and fish.
Modern seasonal health guidelines associated with Lidong encourage adapting routines to conserve vitality during the cold months. Practitioners suggest maintaining adequate warmth, balancing rest, and engaging in low-intensity exercise to support immune health and circulation throughout the winter transition.
