How Do the Twelve Solar Terms Work?
The Chinese calendar is based on the solar year, which is the time it takes for the Earth to orbit the sun. The year is divided into 24 periods, each corresponding to a specific point in the solar cycle. The lengths of the periods vary slightly, with some lasting a bit longer than others, but they are generally around 15 days each.
The Twelve Solar Terms are determined by observing the sun’s position in the sky and the corresponding weather patterns. For example, the Start of Spring is the day when the sun reaches its highest point in the sky, marking the beginning of the growing season.
