Qīngmíng, Seimei, Cheongmyeong or Thanh minh, is the name of the 5th solar term of the traditional Chinese lunisolar calendar,{{cite journal |last1=Zhang |first1=Peiyu |last2=Hunag |first2=Hongfeng( |title=The Twenty-four Solar Terms of the Chinese Calendar and the Calculation for Them |journal=Purple Mountain Observatory |date=1994 |url=https://en.cnki.com.cn/Article_en/CJFDTotal-GXKK403.013.htm}} which divides a year into 24 solar terms ({{small|t.}} 節氣/{{small|s.}} 节气).{{cite web|url = http://eco.mtk.nao.ac.jp/koyomi/faq/24sekki.html.en|title = 24 Sekki|work = Glossary|publisher = National Astronomical Observatory of Japan|access-date = 2016-03-21}} In space partitioning, Qingming begins when the sun reaches the celestial longitude of 15° and ends when it reaches the longitude of 30°. It more often refers in particular to the day when the sun is exactly at the celestial longitude of 15°, usually on April 5.{{cite web|url = https://www.lang.nagoya-u.ac.jp/~matsuoka/24-sekki.html|title = 24 Sekkis, or Twenty-Four Japanese Small Seasons|last = Matsukawa|first = Mitsuharu|publisher = Nagoya University|location = |access-date = 2016-03-21}}

Compared to the space partitioning theory, in the time division theory Qingming falls around April 7 or approximately 106.5 days after winter equinox. In the Gregorian calendar, it usually begins around 4 or 5 April and ends around 20 April.
