BLESSING OR CURSE?
In non-leap years certain countries legally recognize February 29th birthdays on February 28th or March 1st--resulting in hassles with birth certificates, driver's licenses and entry fields on websites. Many Leap Day babies report benefits to playing the 'leap day card', however--receiving discounts and free meals and admissions.

LEAP YEAR MATH
A leap year is a year in the Gregorian calendar with one extra day added to the end of February, making the month 29 days long. The day was established to keep the seasons and the calendar in sync. A year is measured by the amount of time it takes the sun to return to the spot directly above the Earth's equator. Although it actually takes 365.2422 days, we round it to 365. This results in an error of 0.2422 days, or almost 6 hours, per year. After 100 years this calendar would be more than 24 days ahead of the seasons; Leap Day makes up for the inaccuracy. Years that end in '00' can only be a leap year if they are divisible by 400 (so 1900 was not a leap year, but 2000 was).
LEAP YEAR BY THE NUMBERS
--Between 1904 and 2096 Leap Day occurs on the same day of the week every 28 years (so the last time February had five Fridays was in 1980, and the next time will be in 2036).
--The odds of having a leap birthday are 1 in 1,461.
--The longest possible time between two leap years is 8 years. The last time this happened was between 1896 and 1904--and it won't happen again until 2096 to 2104.
--According to the 2000 U.S. Census there are about 200,000 Americans (and 4.1 million people worldwide) who were born on February 29th.
--Norway's Henriksen siblings are recognized by the 'Guinness Book of World Records'. The three siblings were born on three consecutive Leap Days (Heidi Henriksen in 1960; Olav Henriksen in 1964; and Leif-Martin Henriksen in 1968).
