Adjust Clocks Back 1 Hour This Sunday, November 4th


Some of us like it, some of us don't.  But, it's that time of year when we adjust our clocks back 1 hour for Standard Time.  We will do this early Sunday morning, November 4, 2018. This means we gain an hour of sleep (unless you work the overnight shift!)  On Sunday, the sun will rise around 6:35 am and set around 4:40 pm. So, lighter in the morning, darker in the late afternoon. ‚Äč

Here are details about Daylight Time from the Naval Observatory:

By act of Congress, civil clocks in most areas of the United States are adjusted ahead one hour in the summer months (known as daylight time) and returned back one hour in the winter months (known as standard time). The dates marking the beginning and end of daylight time have changed as Congress has passed new statutes. As of 2007, daylight time begins in the United States on the second Sunday in March and ends on the first Sunday in November. On the second Sunday in March, clocks are set ahead one hour at 2:00 a.m. local standard time (which becomes 3:00 a.m. local daylight time). On the first Sunday in November, clocks are set back one hour at 2:00 a.m. local daylight time (which becomes 1:00 a.m. local standard time). These dates were established by Congress in the Energy Policy Act of 2005, Pub. L. no. 109-58, 119 Stat 594 (2005).

Not all places in the U.S. observe daylight time. In particular, Hawaii and most of Arizona do not use it. The most recent change to local daylight time policy was in 2006, when Indiana adopted the use of daylight time state-wide.
