The Leap Year

I’m not going to lab today…just wasting the time surfing internet and watched stupid videos from youtube. The election day is coming and I looked on the calendar just to know what day is going to be (the election day). Suddenly I noticed there is February 29 on the calendar which means this year is the leap year! Wallawei, once in every four years..

I just wondering if there’s any people among my friends that born on 29th February. How they celebrate their birthday?…Are they celebrate it once in every four years or every year just like other people (when it’s not leap year, just pick any day and celebrate your birthday). Hmmm…

Below is some information on leap year taken from http://www.timeanddate.com/date/leapyear.html

So guys, are you born on 29th February? Tell me…

February 29, 2008

Year 2008 is the next leap year, with 29 days in February. February 2008 has five Fridays – it starts and ends on a Friday. Between 1904 and 2096, leap years with same day of week for each date repeat every 28 years which means that the last time February had 5 Fridays was in 1980 and next time will be in 2036.

What is a leap year?

A leap year is a year with one extra day inserted into February, the leap year is 366 days with 29 days in February as opposed to the normal 28 days. (There are a few past exceptions to this)

Which years are leap years?

In the Gregorian calendar, which is the calendar used by most modern countries, the following rules decide which years are leap years:

  1. Every year divisible by 4 is a leap year.
  2. But every year divisible by 100 is NOT a leap year
  3. Unless the year is also divisible by 400, then it is still a leap year.

This means that year 1800, 1900, 2100, 2200, 2300 and 2500 are NOT leap years, while year 2000 and 2400 are leap years.

This actually means year 2000 is kind of special, as it is the first time the third rule is used in many parts of the world.

In the old Julian Calendar, there was only one rule: Every year divisible by 4 is a leap year. This calendar was used before the Gregorian calendar was adopted.

Why are leap years needed?

Leap years are needed so that the calendar is in alignment with the earth’s motion around the sun.
