Daylight Saving Time 2013 Begins On March 10th In The United States

Daylight Saving Time 2013 Starts March 10th In America

Daylight Saving Time, the practice of setting the clock forward by one hour during the warmer part of the year, will begin on March 10 and will end on November 3 this year in the United States.

"Daylight saving time is the part of the year when we advance our clocks by one hour, shifting the time of day in relation to where the Sun is above Earth,"  America's National Institute of Standards and Technology wrote on its website. "In other words, during DST the 'daylight' begins an hour later in the morning and lasts an hour longer in the evening. This change helps keep the hours of daylight coordinated with the time that most people are active. Proponents feel that this saves energy because in the spring and summer months more people may be outside in the evening and not using energy at home. There are, however, ongoing debates about how much energy is saved. The California Energy Commission has additional information about DST and links to several studies about its effects on energy consumption."

Most states in America currently observe Daylight Saving Time, except for Arizona (not including the Navajo Nation, which does follow DST), Hawaii, and the overseas territories of Puerto Rico, American Samoa, Guam, Northern Mariana Islands, and the United States Virgin Island.

Daylight Saving Time starts each year on the second Sunday in March at 2 a.m. (local time). The changeover back to standard time occurs on the first Sunday in November at 2 a.m. (local time).

Some people remember which way to move their clocks using the phrase, "spring forward, fall back."
