Leap Year Tidbits...

Why Leap Year? Most years have 365 days. Leap years have 366 days - the extra day is February 29th. It takes 365.25 days for Earth to circle the Sun (365.256363, a sidereal year, to be more precise!), so the leap year every 4 years is the catch-up day to synchronize the calendar.

Leaping Lizards! Why we like leap years is that you get 1 more day: to TTC, take a vacay day, spend time with family and friends, read, anything...
