February 29 in the Gregorian calendar, the most widely used today, is a date that occurs only once every four years, in years evenly divisible by 4, such as 1976, 1996, 2000, 2004, 2008, 2012 or 2016 (with the exception of century years not divisible by 400, such as 1900). These 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. It is also known as Leap Day.

Leap years

Although the modern calendar counts a year as 365 days, a complete revolution around the sun takes approximately 365 days and 6 hours. Every four years, as 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 in fact 365 days, 5 hours and 49 minutes. To compensate for the 11-minute difference, a century year that ends in two zeros is not a leap year unless it is also evenly divisible by 400. This means that 1600 and 2000 were leap years, as will be 2400 and 2800, but 1800 and 1900 were not, and neither will 2100 and 2200 be. To correct the remaining error (which amounts to one day every 3236 years) it has been proposed that years evenly divisible by 4,000 should not be leap years; but this rule has not been officially adopted.

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.

Adding a leap day (after 23 February) shifts the commemorations in Roman Missal.

The leap day was introduced as part of the Julian reform. The day following the Terminalia (February 23) was doubled, forming the so-called "bis sextum"—literally 'double sixth', since as dates were described in the Roman calendar February 23 was 'the sixth day before the Kalends of March'. The first day of the bis sextum (February 24) came to be regarded as the intercalated or "bissextile" day. 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 are to be reckoned as one day for the purpose of calculating when a full year has passed. Thus, 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. 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 for a birthday that falls on February the 29, and is not a leap year, the legal birth date date shall be the preceding day, the 28th. This is affirmed in s. 2(2) of the Land Transport Act 1999[1], and is affirmed by the Sale of Liqour Act 1989[2] in s. 1(2)(c).

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 Camembert.

Events

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, 1992 would have legally reached 18 years old on February 28, 2010.

"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.

The only notable person known to have both been born and died on February 29 was Sir James Wilson (1812-1880), Premier of Tasmania.
