 Calendar Game (Posted on 2011-01-02)
Two people are playing a game. The first player announces "January 1". From then on, each player announces a date that's later in the year, subject to the proviso that only the month name or the date of the month can change, not both. The object is to be the one to announce "December 31".

If you're the second player, what date do you announce after the first player has announced "January 1", and what is your strategy from there on?

 Submitted by Charlie Rating: 3.0000 (3 votes) Solution: (Hide) You can specify "January 20". From then on, always get back to the sequence "February 21", "March 22", "April 23", ... , "November 30", "December 31". This will always be possible so long as you continue to give one of these dates in each turn. From The Mensa 365 Brain Puzzlers 2010 Calendar, from Page-a-Day publishing, by Mark Danna and Fraser Simpson. Puzzle for December 31.
