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 takes a complete a 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 be 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 13 times on a Sunday, Tuesday, or Thursday; 14
times on a Friday or Saturday; and 15 times on a Monday or
Wednesday. (From Wikepedia)
We're finishing off our quest to earn a smilie
each day of the calendar year at this event and welcome you to do
the same.
