A leap year has 366 days, as opposed to a common year, which has 365. Nearly every 4 years is a Leap Year, and we add a Leap Day, an extra – or intercalary – day on February 29.
Why a event on this day well it can only happen every 4 years and we need it to fill our 366 day caching calendar. So come join us and fill the 29th of February on your caching calendar .
Today we will fill our 366 day caching calendar. Lots of memory's have been made. With lots more to come.
Why do we have Leap Years?
Leap Years are needed to keep our modern day Gregorian Calendar in alignment with the Earth's revolutions around the sun. It takes the Earth approximately 365.242199 days – or 365 days, 5 hours, 48 minutes, and 46 seconds – to circle once around the Sun. This is called a tropical year.
However, the Gregorian calendar has only 365 days in a year, so if we didn't add a day on February 29 nearly every 4 years, we would lose almost six hours off our calendar every year. After only 100 years, our calendar would be off by approximately 24 days!
