閏

Han character

 * 1) intercalary
 * 2) extra, surplus

Glyph origin
. The original meaning “intercalary” is derived from kings' ancient practice of remaining within the palace gates on a leap day (which was in excess of the lunar calendar's 364 days, whence the meanings “remainder” and “surplus”), not engaging in their usual governing functions.
