**This week's problem is a riddle and not really math related. Maybe this kind of riddle will be a nice change from time to time.**

When asked about his birthday, a man said:

"The day before yesterday I was only 25 and next year I will turn 28."

This is true only one day in a year - when was he born?

Solution (from soroban):

[sp]His birthday is December 31.
He spoke on January 1, 2012.

Two days ago (December 30, 2011), he was 25.
On December 31, 2011, he turned 26.

On December 31, 2012 (this year), he turns 27.

Next year (some time during 2013), he will be 28.

*Note from Jameson - More precisely than "some time next year", he will turn 28 on December 31st of next year*[/sp]
