【春江水暖鹅先知 ~】 - the first day of spring in the Northern Hemisphere

 

 

【2014-03-20 the first day in spring】

 

 

春分 秋分 昼夜相庭。

看来老美是以春分为 春天的第一天


spring equinox   春分 在中国是 农历二月廿1日(明天)  2014-3-21  

The season officially begins at 12:57 p.m. ET on March 20 —
a precise and fixed point in time defined as
when the center of the sun passes directly over the Equator.
(See "
Vernal Equinox Pictures: First-Day-of-Spring Celebrations.")

But biological signs of spring's arrival are a different science, defined
by the timing of events—such as the first appearance of flowers —
that change from year to year and place to place.
