When will summer arrive?

Can the landlord clarify the exact meaning of what he said "summer" first?

Summer has many definitions.

1, meteorological summer:

The average daily temperature has remained above 22℃ for five consecutive days, indicating that it is summer.

Judging from this definition, many parts of the country have entered summer (for example, Tianjin began to enter summer on May 3, 20 10; Haikou city entered the summer from 2065438+0065438+1October 30th).

2. Traditional summer:

According to the tradition of China lunar calendar, the moment of "long summer" in the 24 solar terms is late spring and early summer; Summer ends at the beginning of autumn, and autumn begins. In this sense, China began to enter the summer at 22: 44 on May 5, 20 10.

According to the tradition of many western countries, summer begins with "summer solstice" and ends with "autumnal equinox" (there is no saying in the west that there are 24 solar terms, but there is a saying similar to that in China).

In the southern hemisphere, 65438+February and 65438+ 10 every year and February of the following year are generally designated as summer.
