Seventh solar term of traditional East Asian calendars
Lìxià (literally "start of summer" or "inauguration of summer") is the 7th solar term according to the traditional Chinese lunisolar calendar, which divides a year into 24 solar terms (節氣).[1]
It begins when the Sun reaches the celestial longitude of 45° and ends when it reaches the longitude of 60°. The word Lixia most often refers specifically to the first day of this period, the day when the Sun is exactly at the celestial longitude of 45°. In the Gregorian calendar, this is around May 5, and the Lixia period ends with the beginning of the next solar term, Xiaoman, around May 21.[2][3]
Lixia signifies the beginning of summer in Chinese culture,[4] and due to the importance of summer in the agrarian society of ancient China, the day is associated with many cultural traditions, which vary by region.[5]
