Yes, it's more than seven months away... but it's never too early to start planning a New Year's Eve party. But which day of the week will New Year's Eve fall on this coming December (2009)? Sure, you can pull up a computer calendar easy enough, but this is the Brain Game! Figure it out:

DECEMBER 2009 will contain exactly
4 MONDAYS and 4 FRIDAYS.

Using only this bit of information, and without
looking at a calendar, determine which
day of the week NEW YEAR'S EVE will fall on.

Here is the ANSWER.

THE ANSWER:

THURSDAY. 

The only way for a 31-day month (like December) to have exactly 4 Mondays and 4 Fridays is if the first day of the month is on Tuesday, and the last day of the month is on Thursday.

So, to answer the question, this coming December, New Year's Eve will occur on Thursday, December 31, 2009.

Friday, January 1 will be the first day of 2010.
