公元前104年《太初历》正式把24节气订于历法,明确了24节气的天文位置,并规定无中气之月为上月的闰月。
阴历每月以合朔之日为首,即以朔日为初一日。每年以正月(中气雨水所在朔望月)的朔日为岁首。
阴历以有节无气之月为闰月,有闰月之年为闰年,闰年有十三个月,平年则十二个月。
阴历一个月为二十九日或三十日,小月29日,大月30日。
公历闰年366天,平年365天。

About

When I was young
I'd listen to the radio
Waiting for my favorite songs
When they played I'd sing along
It made me smile
Those were such happy times
And not so long ago
How I wondered where they'd gone
But they're back again
Just like a long lost friend
All the songs I loved so well
