Editing Leap year (section)

==Chinese calendar==
The [[Chinese calendar]] is [[lunisolar calendar|lunisolar]], so a leap year has an extra month, often called an ''embolismic'' month after the Greek word for it. In the Chinese calendar, the [[leap month]] is added according to a rule which ensures that month 11 is always the month that contains the northern winter [[solstice]]. The intercalary month takes the same number as the preceding month; for example, if it follows the second month (二月) then it is simply called "leap second month" i.e., {{lang-zh|t=閏二月|s=闰二月|p=rùn'èryuè}}.
