  1. Leap-yearnoun

    Leap-year or bissextile is every fourth year, and so called from its leaping a day more that year than in a common year: so that the common year hath 365 days, but the leap-year 366; and then February hath 29 days, which in common years hath but28. To find the leap-year you have this rule: Divide by 4; what’s left shall be For leap-year 0; for past 1, 2,3. John Harris

    That the sun consisteth of 365 days and almost six hours, wanting eleven minutes; which six hours omitted will, in process of time, largely deprave the compute; and this is the occasion of the bissextile or leap-year. Thomas Browne, Vulg. Err.

Wikipedia

  1. Leap year

    A leap year (also known as an intercalary year or bissextile year) is a calendar year that contains an additional day (or, in the case of a lunisolar calendar, a month) added to keep the calendar year synchronized with the astronomical year or seasonal year. Because astronomical events and seasons do not repeat in a whole number of days, calendars that have a constant number of days in each year will unavoidably drift over time with respect to the event that the year is supposed to track, such as seasons. By inserting (called intercalating in technical terminology) an additional day or month into some years, the drift between a civilization's dating system and the physical properties of the Solar System can be corrected. A year that is not a leap year is a common year. For example, in the Gregorian calendar, each leap year has 366 days instead of 365, by extending February to 29 days rather than the common 28. These extra days occur in each year that is an integer multiple of 4 (except for years evenly divisible by 100, but not by 400). The leap year of 366 days has 52 weeks and two days, hence the year following a leap year will start later by two days of the week. In the lunisolar Hebrew calendar, Adar Aleph, a 13th lunar month, is added seven times every 19 years to the twelve lunar months in its common years to keep its calendar year from drifting through the seasons. In the Bahá'í Calendar, a leap day is added when needed to ensure that the following year begins on the March equinox. The term leap year probably comes from the fact that a fixed date in the Gregorian calendar normally advances one day of the week from one year to the next, but the day of the week in the 12 months following the leap day (from March 1 through February 28 of the following year) will advance two days due to the extra day, thus leaping over one day in the week. For example, Christmas Day (December 25) fell on a Friday in 2020, Saturday in 2021, Sunday in 2022, and will be on a Monday in 2023, but then will leap over Tuesday to fall on a Wednesday in 2024. The length of a day is also occasionally corrected by inserting a leap second into Coordinated Universal Time (UTC) because of variations in Earth's rotation period. Unlike leap days, leap seconds are not introduced on a regular schedule because variations in the length of the day are not entirely predictable. Leap years can present a problem in computing, known as the leap year bug, when a year is not correctly identified as a leap year or when February 29 is not handled correctly in logic that accepts or manipulates dates.

  1. leap year

    A leap year is a year, typically occurring every four years, which has 366 days instead of the standard 365 days. This additional day is added in February, making it 29 days long. The purpose of a leap year is to synchronize the calendar year with the solar year or the length of time it takes the Earth to complete its orbit around the sun, which is about 365.25 days. However, years that are divisible by 100 are not leap years, unless they are also divisible by 400.

Webster Dictionary

  1. Leap year

    bissextile; a year containing 366 days; every fourth year which leaps over a day more than a common year, giving to February twenty-nine days. See Bissextile

  1. Leap year

    A leap year is a year containing one additional day 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 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. For example, in the Gregorian calendar, February in a leap year has 29 days instead of the usual 28, so the year lasts 366 days instead of the usual 365. Similarly, in the Hebrew calendar, Adar Aleph, a 13th lunar month is added seven times every 19 years to the twelve lunar months in its common years to keep its calendar year from drifting through the seasons. The term leap year gets its name from the fact that while a fixed date in the Gregorian calendar normally advances one day of the week from one year to the next, in a leap year the day of the week will advance two days due to the year's extra day inserted at the end of February. For example, Christmas Day fell on Saturday in 2004, Sunday in 2005, Monday in 2006 and Tuesday in 2007 but then "leapt" over Wednesday to fall on a Thursday in 2008.
