闰年
Leap Years
The Chinese calendar features 12 months有12个月份. However, an extra month is inserted in the calendar when a leap year occurs每逢闰年时要添加一个月. Therefore, leap years in the Chinese calendar have 13 months, unlike leap years in the Gregorian calendar公历 in which an extra day is included添加一天. A leap month is added to 添加the Chinese calendar approximately every three years (7 times in 19 years). The name of the leap month is the same as the previous lunar month闰月的名称与之前的阴历月份名称相同. A leap year in the Chinese calendar does not necessarily不一定 fall at the same time a leap year occurs in the Gregorian calendar.
The Chinese calendar's origins can be traced as far back as追溯到 the 14th century BCE.

It is believed that the Emperor Huangdi (Huang Ti or Huang Di)黄帝 introduced the calendar between 3000 and 2600 BCE, or around 2637 BCE.
黄历，又称老黄历、皇历，是在中国农历基础上产生出来的，带有每日吉凶宜忌的一种万年历。黄历相传是由轩辕黄帝创制，故称为黄历。黄历主要内容为二十四节气，每天的宜忌、干支、值神、星宿、月相、吉神凶煞等。
黄历是古时帝王遵循的一个行为规范的书籍，并由钦天监计算颁订，因此也称皇历；这里面不但包括了天文气象、时令季节而且还包含了人民在日常生活中要遵守的一些禁忌，其内容指导中国劳动农民耕种时机，故又称农民历；中国民间俗称为通书；但因通书的“书”字跟“输”字同音，因避忌故又名通胜。
在现代，黄历的主要内容包括：公历、农历和干支历三套历法，二十四节气与礼拜天（星期）、宜忌、冲煞、方位、流年、太岁、三元九运、玄空九星等等。

This widespread change occurred on October 1, 1949, when Mao Zedong, who led the People's Republic of China, ordered that the year should be in accord with保持一致 the Gregorian calendar.
