“冬至”常识是错的,你get了吗?

新华网广东频道     2017-12-22

  《中国天文年历》显示,北京时间12月22日零时28分,将迎来“冬至”节气。

  冬至时间基本在每年的阳历12月21日至22日之间,这一天太阳运行至黄经270度,阳光几乎直射南回归线,北半球白天最短,黑夜最长,所以冬至在我国历代也称为“日短”“日短至”“日南至”。过了冬至,白天就会一天天变长。在我国民间,有“吃了冬至饭,一天长一线”的说法。

  冬至意味着一年中最冷的季节到来。关于冬至的基本知识还是要get的才好。

  【冬至是新年的开始 不是旧年的结束】

  很多人认为,冬至之后是春节,这一年终于要过完了。其实在中国历史中,由周到秦,以冬至日当作岁首的概念一直没有变过。

  《汉书》有云:“冬至阳气起,君道长,故贺……”以农业为主导产业的古人们认为,自冬至起,天地阳气开始兴作渐强,是时候下地干活了。于是,冬至代表下一个循环开始,是大吉之日。

  【冬至这天不算冷,只是最冷季节的开端】

  听到“冬至”二字,很多人就有触冰的感觉。其实作为数九的第一天,冬至其实并不是最冷的时候。

  科学解释是:冬至这天,地球表面有大气和水分,能够储存热量,并不是“即存即失”,而有“积热”。但是随着每天散失的热量越来越大,而太阳提供的热度越来越少,地面标呈现“入不敷出”的状况。此时如果有冷空气的影响,天气就更为寒冷。待到过了这个“冷锋”之后,天气就会渐渐变暖,春天也就紧随而至了。

  【冬至只有吃饺子的习俗吗?】

“冬至大如年”,所以很多人一早就给自己和家人预订了饭店位置,吃水饺去。

  其实,在除了有冬至吃饺子的习俗,各地在冬至时有不同的风俗 ,北方地区有冬至宰羊、吃饺子、吃馄饨的习俗,南方地区在这一天则有吃冬至米团、冬至长线面的习惯 ,而苏南人在冬至时吃大葱炒豆腐。
