lunisolar calendar s that matches a particular astronomical event or signifies some natural phenomenon. The points are spaced 15° apart along theecliptic and are used by lunisolar calendars to stay synchronized with the seasons. Solar terms originated inChina , then spread toKorea ,Vietnam , andJapan . This is exhibited by the fact thattraditional Chinese ,Hanja , andKanji characters for most of the solar terms are identical.Because the
Sun 's speed along the ecliptic varies depending on the Earth-Sun distance, the number of days that it takes the Sun to travel between each pair of solar terms varies slightly throughout the year. Each solar term is divided into three pentads (候 "hou"). Each pentad consists of five days (rarely six), so there are 72 pentads in a year.List of solar terms

In Japan, the term
Setsubun (節分) originally referred to the eves ofRisshun (立春, 315°, the beginning of Spring)Rikka (立夏, 45°, the beginning of Summer),Risshū (立秋, 135°, the beginning of Autumn), andRittō (立冬, 225°, the beginning of Winter), but currently mostly refers to the day before Risshun.
