'''February 29''' is a ''[[leap day]]'' (or "leap year day")—an [[intercalation (timekeeping)|intercalary date]] added periodically to create [[leap year]]s in the [[Julian calendar|Julian]] and [[Gregorian calendar]]s. It is the 60th day of a leap year in both Julian and Gregorian calendars, and 306 days remain until the end of the leap year. It is the last day of [[February]] in leap years only. It is also the last day of [[meteorological winter]] in the [[Northern Hemisphere]] and the last day of [[meteorological summer]] in the [[Southern Hemisphere]] in leap years.
'''February 29''' is known as a ''[[leap day]]'' (or "leap year day"), which is periodically added as the last day of the month to the [[Julian calendar|Julian]] and [[Gregorian calendar]]s, as an [[intercalation (timekeeping)|intercalary date]], to create [[leap year]]s. Its main function is to keep the calendars aligned with the Earth's seasons, as the planet orbits the sun.  


In the Gregorian calendar, the standard [[civil calendar]] used in most of the world, February 29 is added in each year that is an integer multiple of four, unless it is evenly divisible by 100 but not by 400. For example, [[1900]] was not a leap year, but [[2000]] was. The Julian calendar—[[Adoption of the Gregorian calendar#Adoption in Eastern Europe|since 1923]] a [[liturgical calendar]]—has a February 29 every fourth year without exception. Consequently, February 29 in the Julian calendar, since 1900, falls 13 days later than February 29 in the Gregorian, until the year 2100.<ref>{{cite web| url=https://aa.usno.navy.mil/faq/calendars | title= Introduction to Calendars | date=n.d.|publisher= [[United States Naval Observatory]] |accessdate=9 May 2022}}</ref>
In the older Julian calendar, leap days are added to every year that is evenly divisible by four. However, this causes the calendar to slowly become misaligned with the Earth's seasons, by about 3 days every 400 years.<ref>{{cite web| url=https://aa.usno.navy.mil/faq/calendars | title= Introduction to Calendars | date=n.d.|publisher= [[United States Naval Observatory]] |accessdate=9 May 2022}}</ref> (The Julian calendar continues to be used in some places as the basis for their [[liturgical calendar]]).


The convention of using February 29 was not widely accepted before the 15th century; from Julius Caesar's edict in 45 BC until the 16th century (formally), [[Bissextile day|February 24 was doubled]] instead.<ref>{{Cite book|title=A Handbook of Dates for students of British History |editor-first= Christopher Robert  |editor-last=Cheney | others= Revised by Michael Jones |year= 2000 |orig-date=1945 |publisher= [[Cambridge University Press]] |location=Cambridge |isbn=9780521778459 |page=https://archive.org/details/cheney-handbook-of-dates/page/145/mode/1up 145}}</ref> In [[Adoption of the Gregorian calendar#Sweden|one of its attempts to adopt the Gregorian calendar]], Sweden tried (unsuccessfully) to phase in the change by omitting leap days in the 11 successive leap-years, 1700{{ndash}}1740.<ref name="Lamont">{{cite journal |first=Roscoe |last=Lamont |url=https://adsabs.harvard.edu/full/1920PA.....28...18L |title=The reform of the Julian calendar] (II) |journal=Popular Astronomy |volume=8 |year=1920|pages=24–25|bibcode=1920PA.....28...18L }}</ref>
The Gregorian calendar is the standard [[civil calendar]] used in most of the world, and is a slight modification of the Julian calendar. In this calendar, a [[wikt:centennial|centennial]] year does not have a February 29 (despite being evenly divisible by 4) unless it is also evenly divisible by 400. Thus, in contrast to the Julian calendar, the years 1700, 1800 and [[1900]] did not have leap year days but both calendars had a February 29 in the years 1600 and [[2000]].
 
The convention of adding a "February 29" to be the leap day was not widely used before the 15th century. Instead, beginning with Julius Caesar's calendar edict of 45 BC until the 16th century (formally), [[Bissextile day|February 24 was doubled]]{{snd}} two successive days had the same date.<ref>{{Cite book|title=A Handbook of Dates for students of British History |editor-first= Christopher Robert  |editor-last=Cheney | others= Revised by Michael Jones |year= 2000 |orig-date=1945 |publisher= [[Cambridge University Press]] |location=Cambridge |isbn=9780521778459 |page=https://archive.org/details/cheney-handbook-of-dates/page/145/mode/1up 145}}</ref>  
 
February 29 is the 60th day of a leap year for both the Julian and Gregorian calendars, and 306 days remain until the end of the leap year. It is also the last day of [[meteorological winter]] in the [[Northern Hemisphere]] and the last day of [[meteorological summer]] in the [[Southern Hemisphere]] in leap years.

February 29 is known as a leap day (or "leap year day"), which is periodically added as the last day of the month to the Julian and Gregorian calendars, as an intercalary date, to create leap years. Its main function is to keep the calendars aligned with the Earth's seasons, as the planet orbits the sun.

In the older Julian calendar, leap days are added to every year that is evenly divisible by four. However, this causes the calendar to slowly become misaligned with the Earth's seasons, by about 3 days every 400 years.[1] (The Julian calendar continues to be used in some places as the basis for their liturgical calendar).

The Gregorian calendar is the standard civil calendar used in most of the world, and is a slight modification of the Julian calendar. In this calendar, a centennial year does not have a February 29 (despite being evenly divisible by 4) unless it is also evenly divisible by 400. Thus, in contrast to the Julian calendar, the years 1700, 1800 and 1900 did not have leap year days but both calendars had a February 29 in the years 1600 and 2000.

The convention of adding a "February 29" to be the leap day was not widely used before the 15th century. Instead, beginning with Julius Caesar's calendar edict of 45 BC until the 16th century (formally), February 24 was doubledTemplate:Snd two successive days had the same date.[2]

February 29 is the 60th day of a leap year for both the Julian and Gregorian calendars, and 306 days remain until the end of the leap year. It is also the last day of meteorological winter in the Northern Hemisphere and the last day of meteorological summer in the Southern Hemisphere in leap years.
