I recently added some events to my online 2009 calendar. For those of you whose brows are now furrowed because you know me, yes, I keep a calendar. (I just rarely refer to it.) Anyway, I made an entry for July 8, 2009, which was shown in "American style dating" as 07/08/09 - a neat sequence where each subsequent number is increased by one. So it made me think...

Including 07/08/09, how many
times will a date like that occur between
now and the end of the 21st century?

HERE is the solution.

SOLUTION:

Six times. After 07/08/09, it will occur on 08/09/10, 09/10/11, 10/11/12, 11/12/13, and 12/13/14. Since there's no 13th month, we won't see it again until 01/02/03 - that's the year 2103.
