X8 - February 29, 1900

WARNING: There was no February 29, 1900. Even though 1900 is evenly divisible by 4, it was not a leap year because it was a turn of the century year ['00] but not divisible evenly by 400.  Watch out for people trying to trick you with curve balls like this. Another curve ball people may throw is giving you non-existent dates for months like November 31.
