Don't Forget: Time To Fall Back An Hour With End Of DST

NEW YORK (CBSnewYork/AP) -- Remember to turn your clock back one hour. Daylight saving time officially ends at 2 a.m. Sunday.

Daylight saving time is in effect for 238 days which is about 65 percent of the year. Back in 2005, Congress passed an energy bill that extended DST to start on the second Sunday of March and end on the first Sunday of November.

Remember, it's fall back an hour. Otherwise, you'll be an hour early for church, golf or whatever. Residents of Hawaii, most of Arizona and some U.S. territories don't have to change since they did not observe daylight saving time.

The FDNY is also reminding folks to check their smoke and carbon monoxide detectors when they turn their clocks back this weekend.

The department is giving out free 9-volt batteries at locations in all five boroughs today and tomorrow.
