leap year

Etymology
From Late, , from , (from , , probably ultimately from ) +  (from , ultimately from ). The English term is analysable as, and possibly relates to the phenomenon that any fixed date of a 365-day calendar advances one weekday each year but every date of a 366-day year after February 29 (often seen as the leap day) advances by two weekdays instead. For example, Christmas (December 25) fell on a Saturday in 2004, a Sunday in 2005, a Monday in 2006, and a Tuesday in 2007 but then “leapt” over Wednesday to fall on a Thursday in 2008 which was a leap year.

Compare also and, an additional day added every 19 years (a Metonic cycle) to bring the lunar and solar calendars into alignment.
