Did you know that May 5-7th is the start of summer according to the Chinese lunisolar calendar? Lixia (立夏) is the 7th solar term, which divides a year into 24 solar terms. Lixia begins when the Sun reaches the celestial longitude of 45° and ends when it reaches the longitude of 60° around May 21st.
