每年的什么時(shí)間入伏?

更新時(shí)間:2021-12-30 18:25:25作者:admin2

每年入伏的時(shí)間不固定,中伏的長短也不相同,需要查歷書計(jì)算,簡單地可以用“夏至三庚”這4字口訣來表示入伏的日期,即從夏至后第3個(gè)“庚”日算起,初伏為10天,中伏為10天,末伏為10天。
三伏天,一伏是十天,這是按照天干的十?dāng)?shù)去計(jì)算的。所以,劃分三伏天,就是:夏至之后的第三個(gè)天干的庚日,為第一伏的開始天;十天之后,又是個(gè)庚日,就進(jìn)入了第二伏;十天之后,又是一個(gè)庚日,就進(jìn)入了第三伏。一般來說,每年進(jìn)入三伏天之后,都是很熱的,特別是第三伏的十天,是最熱的。
