The traditional Chinese solar calendar divides the year into 24 solar terms.

The 24 solar terms are determined by changes in the sun's position in the zodiac during the year. They were first used in China and now are followed in many other parts of the world. In China, the 24 solar terms were created thousands of years ago to guide agricultural production. They also reflect China's rich history through the seasonal festivals, special foods, cultural ceremonies, family gatherings and even healthy living tips that correspond with each solar term.
