What is "xiaoshu"

The traditional East Asian calendars divide a year into 24 solar terms (節氣). Xiǎoshǔ ( pīnyīn), Shōsho ( rōmaji), or Soseo ( romaja) is the 11th solar term. It begins when the Sun reaches the celestial longitude of 105° and ends when it reaches the longitude of 120°. It more often refers in particular to the day when the Sun is exactly at the celestial longitude of 105°. In the Gregorian calendar, it usually begins around 7 July and ends around 22 July (23 July East Asia time).
