Sunday, March 13, 2011 (2am local time) – Sunday, November 6, 2011
Daylight Saving Time (DST) is also called summer time or daylight savings time. It begins at 2:00 A.M. this Sunday, March 13th (second sunday in March). It is a way of getting more light out of the day by advancing clocks by one hour during the summer. During Daylight Saving Time, the sun appears to rise one hour later in the morning, when people are usually asleep anyway, and sets one hour later in the evening, seeming to stretch the day longer.
The clock moves ahead (thus, losing one hour) when DST starts, typically in the spring, and falls back one hour (thus, gaining one hour) when DST ends in the fall. To make it easier to remember which way the clock goes, keep in mind one of these sayings: “spring forward, fall back” or “spring ahead, fall behind.”
So, don’t forget to set your clocks forward this Sunday with the coming of Spring.
