Wanted: A month of weekends

This tidbit popped up in my e-mail Friday:

AN INTERESTING FACT ABOUT *AUGUST 2010*.
This August has 5 Sundays, 5 Mondays, 5 Tuesdays,
all in one month. It happens once in 823 years.
!I'll probably miss the next one.)

Trouble is, it's not true. May 2011 begins on a Sunday and hence has five Sundays, Mondays and Tuesdays.

The next time August has five Sundays, Mondays and Tuesdays? 2021. Better yet, August 2014 will have five Fridays, five Saturdays and five Sundays! Last May also had five Sundays and five Saturdays, but that was followed by five Mondays.

What I like are the months that have the extra paydays.
