oh another February 29...
a slit in the Gregorian calendar
you would've think that Leap Year would've been the word of the day
but not, here anyway Dictionary.com definition of a Leap Year:
"A year that contains 366 days, with February 29 as an additional day: occurring in years whose last two digits are evenly divisible by four, except for centenary years not divisible by 400."
Enjoy your extra day!
