February 29, 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.
Why are leap years needed?
Leap years are needed to keep our calendar in alignment with the earth's revolutions around the sun.
Which years are leap years?
1.In the Gregorian calendar, the calendar used by most modern countries, the following three criteria determine which years will be leap years:
2.Every year that is divisible by four is a leap year;
of those years, if it can be divided by 100, it is NOT a leap year, unless
3.the year is divisible by 400. Then it is a leap year.
According to the above criteria, that means that years 1800, 1900, 2100, 2200, 2300 and 2500 are NOT leap years, while year 2000 and 2400 are leap years.
Other leap years facts
1. The Gregorian calendar has a 400-year cycle until it repeats the same weekdays for every year–February 29, 2008, is a Friday and February 29, 2408, is a Friday.
2. The Gregorian calendar has 97 leap years during those 400 years.
3. 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.
