5月中的农历节气是“立夏”和“小满”,“立夏”是指当年夏季的开始,民间习惯把“立夏”至“立秋”前一天称为夏季,但从气象学的角度上讲,连续4天日平均气温在20℃以上的时段,才算是夏季的开始,从这种意义上讲,真正的夏季是6、7、8月。
In mid-May, the lunar solar terms in the middle of May were “early summer” and “small full.” “Beginning of summer” refers to the beginning of the summer of the year. Folk custom refers to the day before “establishing the summer” to “establishing autumn” as the summer. However, from the meteorological point of view, The average daily temperature of 4 days a day above 20 ℃ is considered the beginning of summer, in this sense, the real summer is June, July and August.
