Spring forward.

This is a directive on the second Sunday of March — this weekend — for clocks in the United States to move forward one hour under daylight-saving time. This means more afternoon sun.

The official clocks of the United States government will change by an hour at 2 a.m. Sunday, March 10, according to the U.S. Department of Transportation, which regulates daylight savings and time zones in the country.

Clocks detached from today's omnipresent Internet will have to be changed manually — unless you are in the rare places in the United States, such as parts of Arizona, Hawaii, Puerto Rico and other island territories that don't prescribe to the change.

For many who use cell phones or other devices that are tapped into networks, the time will be changed automatically by providers.

This is officially the start of the ever-reverting daylight savings program. The hour will be stolen back at 2 a.m. on the first Sunday of November. That is, spring forward, fall back.

According to the National Institute of Standards and Technology, an official timekeeper in the United States, daylight savings "has the effect of creating more sunlit hours in the evening during the months when the weather is the warmest."

Government officials say that daylight savings also saves energy, reduces crime, and even saves lives and prevents traffic injuries.

Many fire departments in the county advise citizens to use daylight savings as a twice-annual reminder to also change batteries in home smoke alarms and carbon monoxide detectors.
