Daylight Saving Time Ends Today

Saturday night—or to be more precise, Sunday at 2 a.m.—marks the end of daylight saving time. Per the "spring forward, fall back" saying, everyone should turn their clocks back an hour today.

The National Fire Protection Association and the U.S. Consumer Product Safety Commission both recommend that people change the batteries in their smoke and carbon monoxide detectors on the same day they change their clocks for daylight saving time.

Homeowners should also recycle the batteries instead of throwing them in the trash, which is illegal in Redondo Beach. Batteries can be dropped off in the brown battery collection receptacles any of the following locations:

• Main Library, 303 N. Pacific Coast Hwy.
• City Clerk's Office, 415 Diamond St.
• Public Works Yard, 531 N. Gertruda Ave.
• Fire Station No. 1,  401 S. Broadway
• Fire Station No. 2,  2400 Grant Ave.
• Anderson Park Senior Center, 2229 Ernest Ave.
• Perry Park Senior Center, 2301 Grant Ave.
• Veteran's Park Senior Center, 309 Esplanade
• Alta Vista Park Community Center, 715 Julia St. 

The California Energy Commission recommends that people also use the opportunity to change at least one incandescent light bulb to an energy-saving compact fluorescent bulb.

Daylight saving time begins at 2 a.m. on the second Sunday in March and lasts until the first Sunday in November, according to the California Energy Commission. Most of Arizona, Hawaii, American Samoa, Guam, Puerto Rico and the Virgin Islands do not observe daylight saving time.

For years, authorities maintained that daylight saving time saved electricity; at one point during the energy crisis, California considered moving to an earlier daylight saving time or staying on daylight saving time year-round.

Nevertheless, more recent studies have concluded that the amount of energy saved is marginal, and one even concluded that daylight saving time increased residential electricity demand.
