Leap Day, February 29, occurs once every four years.
Since the Gregorian Calendar has only been in effect since 24 February 1582, February 29 2008 is only the 103th Leap Day.
Why the change to the Gregorian Calendar, which has an error of 27 seconds per year?
Because it's a great deal more accurate than its predecessors.
Gregorian calendar AD 1582 365.2425 days 27 seconds (1 day every 3,236 years)
Julian calendar 45 BC 365.25 days 11 minutes (1 day every 128 years)
365-day calendar - 365 days 6 hours (1 day every 4 years)
Lunar calendar ancient 12-13 moon-months variable
A little bit about Leap Day 2008.
"The year 2008 is a leap year. If you look at a 2008 calendar, you will see that February has five Fridays–the month begins and ends on a Friday. Between the years 1904 and 2096, leap years that share the same day of week for each date repeat only every 28 years. The most recent year in which February comprised five Fridays was in 1980, and the next occurrence will be in 2036. February 29, the leap day, has been associated with age-old traditions, superstitions and folklore."
What are the legal ramifications of being born on a day that occurs once every four years?
Not as many as you think.
When to celebrate is a matter of personal preference, and the only time having such an unusual birth date really could cause problems is in years when the exact day matters, as getting a driver's license, sipping your first legal cocktail, registering to vote or playing the slots.
Sometimes, registering on a Web site using a Feb. 29 birthday will result in "Invalid birth date," though the Honor Society of Leap Year Day Babies in Oregon, a non-profit advocacy group, offers free software that Web designers can use to avoid the error message.
Statistically, it really doesn't matter what day someone is born on, says Christopher Mrela, statistician with the Arizona Department of Health Services, which maintains the state's vital records. Age is computed by year, not actual birth date. So to celebrate a Leap Day birthday in a non-leap year is not a state concern.
One could go get their driver's license on their actual birth date--this year. But had this not been a leap year, the applicant would have had to wait until March 1."Just like anyone born on any other day, you can't get a driver's license on the day before you are eligible," says Cydney DeModica, spokeswoman for the state's Motor Vehicle Division.
What about gambling in Las Vegas or a glass of wine? Would a person have to wait until March 1? Based on stories from other leap-year babies, it would depend on the pit boss or bartender.
FAST FACT: [And one that we bet you'll not remember for too long after today.]The longest time between two leap years is eight years. The last time that occurred was between 1896 and 1904. The next time will be between 2096 and 2104.
For a day that has only occured 102 times previously, a lot has happened on February 29.
