Friday the Thirteenths
We've decided to do a recurring feature at LessThanDot and
have a "Programmer Puzzles" section with interesting puzzles published.
This week the challenge has been set to "identify all friday the
thirteenths for a given timeframe". You can use any programming language you like, just please let people know which one you have decided to use!
