Daylight Saving Time ends on the first Sunday of November each year in the U.S. (with the exception of Arizona and Hawaii). In 2013, that will be Sunday, November 3rd at 2 a.m.
At 1:59:59 a.m. on Sunday, your clocks will revert back to 1 a.m. Yes! FALL BACK!! An extra hour of sleep!
The Energy Policy Act of 2005 gave us an extra month of DST by starting DST 3 weeks earlier and ending it one week later.
For my more precise readers, it is officially called Daylight Saving (not Savings) Time. So if you want to annoy your friends, correct them any time they call it Daylight SavingS time.
Also as one website I found mentioned, Daylight Saving Time is technically inaccurate, since we don't really gain daylight. It would more appropriately be called Daylight Shifting Time but I don't see that being a high priority initiative.
Falling back is probably my favorite day of the year as I thoroughly enjoy the gift of an extra hour. I despise the Daylight Saving Time transition and rant about it here.
