This October has 5 Fridays, 5 Saturdays and 5 Sundays, all in one month.
It happens once in 823 years


Just thought of sharing this, since i'm bored :P
ive just noticed it in the calendar , very nice info :)
It doesn't happen once every 823 years. It happens when a 31-day month starts on Friday. Like for example, January 2010. (Unlike December though).
