Mangzhong
The traditional East Asian calendars divide a year into 24 solar terms (節氣). Mángzhǒng ( pīnyīn) or more commonly pronounced as Mángzhòng, Bōshu ( rōmaji), or Mangjong ( romaja) is the 9th solar term. It begins when the Sun reaches the celestial longitude of 75° and ends when it reaches the longitude of 90°. It more often refers in particular to the day when the Sun is exactly at the celestial longitude of 75°. In the Gregorian calendar, it usually begins around June 5 (June 6 East Asia time) and ends around June 21.
