Today. February 29th. In History. (LEAP-DAY)
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 2004, 2008, 2012 and 2016. 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.
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. A better approximation, derived from the Alfonsine tables, is that the Earth makes a complete revolution around the sun in 365 days, 5 hours, 49 minutes, and 16 seconds. To compensate for the difference, an end-of-century year is not a leap year unless it is also exactly divisible by 400. This means that the years 1600 and 2000 were leap years, as will be 2400 and 2800, but the years 1700, 1800 and 1900 were not, nor will 2100, 2200 and 2300.
The Gregorian calendar repeats itself every 400 years, which is exactly 20,871 weeks including 97 leap days. Over this period, February 29 falls on Sunday, Tuesday, and Thursday 13 times each; 14 times each on Friday and Saturday; and 15 times each on Monday and 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 the 1962 Roman Missal.
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. 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.
In the United Kingdom and Hong Kong, a person born on February 29 legally attains the age of 18 on March 1 in the relevant year.
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, February 28. This is affirmed in the Land Transport Act 1999.
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.

A person who is born on February 29 may be called a "leapling" or a
"leap year baby". In non-leap years, some leaplings celebrate their birthday on either February 28 or March 1, while others only observe birthdays on the authentic intercalary dates.
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 March 1 in common years. The same applies in Hong Kong as well (see Leap Years, above). In Taiwan (Republic of China)
and in New Zealand, the legal birthday of a leapling is February 28 in
common years. So in England and Wales or in Hong Kong, a person born on
February 29, 1996 will have legally reached 18 years old on March 1,
2014; in Taiwan and in New Zealand he or she legally becomes 18 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"
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. It may be worked out from the opera's dialogue
that Frederic's birthday is February 29, 1852 thus making the opera set
in 1873. (This assumes that Frederic is aware that 1900 will not be a
leap year. If not, the dates would be later by four years.)
In the manga and anime series Ouran High School Host Club, the character Mitsukuni Haninozuka,
also known as "Honey" or "Hunny", was born on February 29. He is
depicted as being small and cute, and one of the reasons given why he is
so small being that he was born on February 29, the idea being that,
"Because his birthday comes once every four years, he grows once every
four years", according to creator Bisco Hatori
