We all know the "Set Your Clock Back" routine for Daylight Saving Time, but it's always easy to forget exactly when the date is.

For 2009, Daylight Saving Time ends at 2:00 a.m. on Sunday, November 1st. So don't forget to set your clocks back one hour before you go to bed on Saturday night (or do it right at 2 a.m., if you'll be partying or will just happen to be awake at that time).
