2008 is a leap year, which means that it has 366 days instead of the usual 365 days that an ordinary year has. An extra day is added in a leap year—February 29—which is called an intercalary day or a leap day.
How would you like to have been born on a leap year? I heard of a lady today that was born 96 years ago on a leap year. She said it was kind of difficult not having a day to celebrate her birthday on the leap years. hmmm??? What would you do?
Why is a Leap Year Necessary?
Leap years are added to the calendar to keep it working properly. The 365 days of the annual calendar are meant to match up with the solar year. A solar year is the time it takes the Earth to complete its orbit around the Sun—about one year. But the actual time it takes for the Earth to travel around the Sun is in fact a little longer than that—about 365¼ days (365 days, 5 hours, 48 minutes, and 46 seconds, to be precise). So the calendar and the solar year don’t completely match—the calendar year is a touch shorter than the solar year.
It may not seem like much of a difference, but after a few years those extra quarter days in the solar year begin to add up. After four years, for example, the four extra quarter days would make the calendar fall behind the solar year by about a day. Over the course of a century, the difference between the solar year and the calendar year would become 25 days! Instead of summer beginning in June, for example, it wouldn’t start until nearly a month later, in July. As every kid looking forward to summer vacation knows—calendar or no calendar—that’s way too late! So every four years a leap day is added to the calendar to allow it to catch up to the solar year.
Rules for determining a Leap Year:
- Most years that can be divided evenly by 4 are leap years.
(For example, 2008 divided by 4 = 502: Leap year!) - Exception: Century years are NOT leap years UNLESS they can be evenly divided by 400. For example, 1700, 1800, and 1900 were not leap years, but 1600 and 2000, which are divisible by 400.
