An Extra Day this Year!?!

Leap Year
We get an extra day this year!!  What do you have planned?  For me it will be like every other day?!?!

Leap Years are needed to keep our 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 (a tropical year)– to circle once around the Sun.
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!
The reason I know this?  Because my son is studing Astronomy for a Merit Badge.  My, the things you can learn when you have too. 
Hoping every one will ENJOY their extra day because it will not come again for another 4 years!
