Guyu
The traditional East Asian calendars divide a year into 24 solar terms (節氣). Gǔyù (pīnyīn) or more commonly pronounced as Gǔyǔ, Kokuu (rōmaji), or Gogu (romaja) (traditional Chinese and Japanese: 穀雨;simplified Chinese: 谷雨;Korean: 곡우;Vietnamese:Cốc vũ;literally: "grain rain") is the 6th solar term. It begins when the Sun reaches the celestial longitude of 30° and ends when it reaches the longitude of 45°. It more often refers in particular to the day when the Sun is exactly at the celestial longitude of 30°. In the Gregorian calendar, it usually begins around April 20 and ends around May 5.
