桃花开,蜂蝶舞,候鸟鸣,春到人间。但是你是否知道春天从哪一天开始。按我国夏历规定,春天是从“立春”这一天(2月5日)开始,至“立夏”止。古书上则有“春三月”的说法,即孟春正月、仲春二月、季春三月,春天从正月初一开始。欧洲人把阳历的1、2、3月称作春天,他们认为元旦是春天的起点。科学的计算春天是按气候学而定,即平均气温为10—22℃算作春天的标准温度,也就是温和的气候是春,炎热为夏,凉爽为秋,寒冷为冬。以此标准划分,则各地春到人间之日期不同:广州为11月初,重庆为2月中,北京为4月初,沈阳为4月底,爱辉为5月中。昆明地区1月均温为9.6℃,7月均温为20.1℃,故号称四季如春。

Europeans refer to January, February and March of the Gregorian calendar as spring, and they think New Year’s Day is the starting point of spring.

Divided by this standard, the spring to the earth around the different dates: Guangzhou in early November, Chongqing in February, Beijing is early April, Shenyang is the end of April, Ai Hui is mid-May.
