What festival is the last night?

The last day does not belong to the 20 solar terms, but to the dog days, and the last day is coming to an end. The dog days are the highest, hottest and wettest stage in a year, which occurs between the annual summer solar terms.

The dog days can be divided into three stages, namely the first day, the second day and the last day. Generally speaking, counting backwards from the summer solstice to the third Geng day means entering the first dog days, and the fourth Geng day enters the middle dog days, while the first Geng day after beginning of autumn means entering the last dog days. Generally speaking, the duration of each dog day is 10 days.

In dog days, medium is the hottest period.
