1, the summer heat time in 2022 is July 7 10: 37: 49, which is on Thursday, June 9, the lunar calendar. Slight heat is "slight heat", which means that although we can already feel the hot weather at this time, it has not reached the hottest in a year, and it is only the beginning of a hot summer day.

2. There is still a certain difference between a little summer heat and falling in.
