29th of February..

Ive being researching and I found out that in the Gregorian calendar, the current standard calendar in most of the world, most years that are evenly divisible by 4 are leap years. In each leap year, the month of February has 29 days instead of 28. Adding an extra day to the calendar every four years compensates for the fact that a period of 365 days is shorter than a solar year by almost 6 hours. So that would have 29 days even though its February. So the next February 29th would be in 2012. In 2008, there was an 29th of February. Since a leap year consists of 366 days, whereas other years, called common years, have 365 days. Thats why February would have an extra day added up into it. And we would see a 29th of February every 4 years.
