Tea Harvest Calendar

Throughout the year, the relative positions of the sun and the earth can be expressed by 24 solar terms. Dates marking these 24 solar terms stay almost the same year by year on the international calendar. The 24 solar term marks directed a lot of agricultural activities in traditional society of China, including tea cultivation. On this Tea Harvest Calendar, the harvest dates of various teas are sorted in temporal order based on the solar terms they belong to.

More information about the 24 solar terms can be found on this webpage of Hong Kong government:


(Name translations of the solar terms are slightly different between this Tea Harvest Calendar and above webpage.)

Tea harvest dates vary slightly from year to year. The system of solar terms helps us understand how tea harvest is connected to climatic patterns.

This Tea Harvest Calendar includes names of the 24 solar terms in English and Chinese, their dates on the international calendar, and harvest times of some well-known Chinese teas. Additional notes are made about climatic changes and traditional agricultural events of some solar terms.
