A leap year (or intercalary or bissextile year) is a year containing one additional day (or, in the case of lunisolar calendars, a month) in order to keep the calendar year synchronized with the astronomical or seasonal year. Because seasons and astronomical events do not repeat in a whole number of days, a calendar that had the same number of days in each year would, over time, drift with respect to the event it was supposed to track. By occasionally inserting (or intercalating) an additional day or month into the year, the drift can be corrected. A year that is not a leap year is called a common year.

A leap year is a year with an extra day. Leap year may also refer to:

• Leap Year (1921 film) – American film
• Leap Year (1932 film) – British film
• Leap Year (2010 film) – American film
• Leap Years – a 2001 drama television series
• The Leap Years – 2008 Singaporean film, aka Leap of Love
• Año bisiesto (Leap Year) - a Mexican film and winner of the 2010 Caméra d'Or at the Cannes Film Festival

Skottar är människor ifrån landet Skottland.

Ett skottår är ett år med en skottdag. I lunisolarkalendrar som judiska, babyloniska och den gamla romerska kalendern innebär skottår att året har en extra månad - skottmånad.

Eit skotår er eit år som har ein dag meir enn eit normalt år.
