The traditional Chinese lunar calendar divides the year into 24 solar terms. Winter Solstice, the 22nd solar term of the year, begins this year on Dec 22 and ends on Jan 5.

中國傳統(tǒng)二十四節(jié)氣的第22個節(jié)氣是冬至，今年的冬至從12月22日開始，1月5日結(jié)束。

On the first day of Winter Solstice, the Northern Hemisphere experiences the shortest day and the longest night in the year, as the sun shines directly at the Tropic of Capricorn. From then on, the days become longer and the nights become shorter. The Winter Solstice also marks the arrival of the coldest season in the year.

冬至節(jié)氣的第一天，由于太陽直射南回歸線，北半球白晝最短，黑夜最長。冬至過后，白晝變長，黑夜變短。冬至也意味著一年最冷的時節(jié)來臨。

The Winter Solstice Festival

冬至大如年

There was a saying in ancient China, "The Winter Solstice is as significant as the Spring Festival."

中國有句古話叫：“冬至大如年。”

As early as the Zhou Dynasty (c.11th century-256 BC), people worshipped the gods on the first day of the Winter Solstice, which also was the first day of the new year. The Winter Solstice became a winter festival during the Han Dynasty (206 BC-AD 220). The celebratory activities were officially organized. On this day, both officials and common people would have a rest.

早在周朝時期（公元前約11世紀(jì)-公元前256年），人們就在冬至這天祭拜神靈，冬至還是新年的第一天。冬至在漢朝（公元前206年-公元220年）成為一個冬季節(jié)日，在這天會舉行正式的慶?；顒?，官員和百姓均可休息。

During subsequent dynasties, such as the Tang (618-907), Song (960-1279) and Qing dynasties (1644-1911), the Winter Solstice was a day to offer sacrifices to Heaven and to ancestors.

在后來的朝代，比如唐朝（公元618年-907年）、宋朝（公元960年-1279年）和清朝（公元1644年-1911年），冬至成為祭天祭祖的節(jié)日。
