The 24 solar terms: the Sun’s annual cycle and seasonal culture

In modern calendars, the 24 solar terms divide the Sun’s path along the ecliptic into 15-degree intervals of solar longitude. The spring equinox is at 0 degrees, the summer solstice at 90, the autumn equinox at 180 and the winter solstice at 270. They divide the Sun’s annual cycle and are not determined solely by lunar phases.

Their sequence is: Start of Spring, Rain Water, Awakening of Insects, Spring Equinox, Clear and Bright, Grain Rain, Start of Summer, Lesser Fullness, Grain in Ear, Summer Solstice, Lesser Heat, Greater Heat, Start of Autumn, End of Heat, White Dew, Autumn Equinox, Cold Dew, Frost’s Descent, Start of Winter, Lesser Snow, Greater Snow, Winter Solstice, Lesser Cold and Greater Cold. Gregorian dates and exact times vary slightly from year to year.

The names carry historical Chinese farming and seasonal observations. Actual climates differ with latitude, altitude and hemisphere. When living overseas, appreciate their cultural meaning while following local weather and seasons.
