July 7 in 2021
Shōsho (小暑) is the 11th of 24 solar terms in the traditional East Asian calendars.
Shōsho (小暑) literally means small heat.
The end of the rainy season is near, and it gets really hot around this time. Cicadas start to chirp.
From Shōsho (小暑, July 7th) or Taisho (大暑, July 22nd) to around Risshū (立秋, August 7th) is Shocyū (暑中, mid-summer on the calendar) and it is the period people send Shochū-mimai (暑中見舞い, postcards or letters offering best wishes for the hot season) to their friends and relatives.
