Ideogrammic compound (會意 / 会意): 門 (“gate”) + 王 (“king”). 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.
