24 Solar Terms —
How the Ancient Chinese Determined New Year's Day?

Chinese 24 Solar Terms are determined by positions of earth on the Ecliptic — the earth’s orbit around the sun. Each Solar Term is 15° apart on the Ecliptic. The 24 Solar Terms integrate information on the plant cultivation time and climate for farmers in the Northern Hemishere. The dates of these Solar Terms is closely followed by the Gregorian calendar.
