In what month does Huangmei Tian usually fall in Shanghai?

Huang Meitian is from mid-June to mid-July.

Huangmeitian means plum rainy weather. In early summer, a period of long-lasting gloomy and rainy weather often occurs in the middle and lower reaches of the Yangtze River. At this time, utensils are prone to mold, so it is called "mold rain", or "mold" for short. It is also the time when the plums in the south of the Yangtze River are yellow and ripe, also known as "plum rain" or "yellow plum rain".

Chinese almanacs always have records of the beginning and end of mildew rain: the beginning day is called "mildew entering" and the end day is called "mildew coming out". Mold will appear on the first C day after the Ear seeds are planted, and mold will appear on the first day after the Slight Heat. The onset of mildew is always between June 6th and 15th, and the onset of mildew is always between July 8th and 19th.

Examples of plum blossoms:

If the day of the awn is on June 6, 2006, which is Bingyin day, then the plum blossom will be on the day of the awn; July 17 after the minor summer heat The sun is at the end of the day, so the plum blossom date in 2006 is July 17. Huangmeitian***42 days. The specific mental algorithm is as follows.

Enter the Mei Bing day formula: D=(7-Y)Mod10, where Y=(5(odd number)+[last 2 digits of the year/4])Mod10. Y in 2006= [6/4]=1, D=7-1=6, so the plum season is June 6th. The formula for the last day of plum blossoms: D=12-Y, this year’s Y=(6×5+[6/4]) Mod12=7 (see the entry for plum blossoms for details), D=12-7=5, because July 5th is before Xiaoshu, so plum blossoms = 5+12=17th.
