February 29, known as a leap day in the Gregorian calendar, is a date that occurs in most years that are evenly divisible by 4, such as 1976, 2004, and 2008. Years that are evenly divisible by 100 do not contain a leap day, with the exception of years that are evenly divisible by 400, which do contain a leap day; thus 1900 did not contain a leap day while 2000 did. Years containing a leap day are called leap years. February 29 is the 60th day of the Gregorian calendar in such a year, with 306 days remaining until the end of that year.
Leap years
Although most years of the modern calendar have 365 days, a complete revolution around the sun takes approximately 365 days and 6 hours. Every four years, during which an extra 24 hours have accumulated, one extra day is added to keep the count coordinated with the sun's apparent position.
It is however slightly inaccurate to calculate an additional 6 hours each year as the time actually taken for the earth to complete a revolution around the sun is 365 days, 5 hours and 49 minutes. To compensate for the 11-minute difference, an end-of-century year is not a leap year unless it is also exactly divisible by 400. This means that 1600 and 2000 were leap years, as will be 2400 and 2800, but 1800 and 1900 were not, nor will be 2100, 2200 and 2300.
The Gregorian calendar repeats itself every 400 years, which is exactly 20871 weeks including 97 leap days. Over this period February 29 falls 13 times on a Sunday, Tuesday or Thursday; 14 times on a Friday or Saturday; and 15 times on a Monday or Wednesday.
The concepts of the leap year and leap day are distinct from the leap second, which results from changes in the Earth's rotational speed.
The leap day was introduced as part of the Julian reform. The day following the Terminalia (February 23) was doubled, forming the "bis sextum"—literally 'double sixth', since February 24 was 'the sixth day before the Kalends of March' using Roman inclusive counting (March 1 was the 'first day'). Although exceptions exist, the first day of the bis sextum (February 24) was usually regarded as the intercalated or "bissextile" day since the third century.[1] February 29 came to be regarded as the leap day when the Roman system of numbering days was replaced by sequential numbering in the late Middle Ages.
An English law of 1256 decreed that in leap years, the leap day and the day before (February 25 & 24) are to be reckoned as one day for the purpose of calculating when a full year had passed. In England and Wales a person born on February 29 legally reaches the age of 18 or 21 on February 28 of the relevant year[citation needed]. In the European Union, February 29 officially became the leap day only in 2000.[citation needed]
In cases of New Zealand citizens, the NZ Parliament has decreed that if a date of birth was February 29, in non-leap years the legal birth date date shall be the preceding day, the 28th. This is affirmed in §2(2) of the Land Transport Act 1999.[2]
In France, there is a humorous periodical called La Bougie du Sapeur (The Sapper's Candle) published every February 29 since 1980. The name is a reference to the sapper Camember, a comic strip character born February 29, 1844 who was created by Georges Colomb in the 1890s.

Births
A person who was born on February 29 may be called a "leapling" or a "leap year baby". In non-leap years they typically celebrate their birthday on either February 28 or March 1.
For legal purposes, their legal birthdays depend on how different laws count time intervals. In England and Wales the legal birthday of a leapling is February 28 in common years (see Leap Years, above). In Taiwan the legal birthday of a leapling is also February 28 in common years. In both cases, a person born on February 29, 1996 will have legally reached 18 years old on February 28, 2014.
- "If a period fixed by weeks, months, and years does not commence from the beginning of a week, month, or year, it ends with the ending of the day which proceeds the day of the last week, month, or year which corresponds to that on which it began to commence. But if there is no corresponding day in the last month, the period ends with the ending of the last day of the last month.[3]"
There are many instances in children's literature where a person's claim to be only a quarter of their actual age turns out to be based on counting their leap-year birthdays. A similar device is used in the plot of Gilbert and Sullivan's 1879 comic opera The Pirates of Penzance: As a child, Frederic was apprenticed to a band of pirates until the age of 21. Now, having passed his 21st year, he leaves the pirate band and falls in love. However, it turns out that the pirate indenture says that his apprenticeship does not end until his 21st birthday, and since he was born on February 29, that day will not arrive until he is in his eighties. As such, he must leave his fiancée and return to the pirates.
