Daylight Saving Time, Standard Time, and Time Zones: The Politics of the Clock
In most of the US, the second Sunday in March marks Daylight Saving Time. At 2 a.m. EST, the time becomes 3 a.m. EST. If you are in the US, you will want to turn your clocks forward an hour. This means you lose an hour.
On the first Sunday in November, most people in the US switch back to Standard Time by moving their clocks back an hour from 2 a.m. to 1 a.m.
