This month’s half-back day is Tuesday, 12/16/14. Go up four from 12 to 16 and come halfway back from 16 to 14.

This week may look like just another week with lots of even numbers for month, day, and year.  There are four such dates: Sunday, Tuesday, Thursday, Saturday are 12/14, 12/16, 12/18, and 12/20.   But say goodbye for a while.  The next time one week has four all-even numbered dates is  more than a year away – the week of February 14, 2016.
