Now that Labor Day is over and the kids are back in school, summer is becoming a distant memory and fall’s cooler weather is on the horizon.

The end of summer also means shorter days are coming, with the sun setting before some of us can even escape the office.

Daylight saving time, which gave us an extra hour of sunlight back in March, is also set to end in the coming months. Though we will get that extra hour of sleep, the days will be even darker.

In 2007, the Energy Policy Act of 2005 extended the length of DST by about one month “in the interest of reducing energy consumption,” according to But Congress can still “revert to the prior law should the change prove unpopular or if energy savings are not significant.”

Currently, in the U.S., DST begins at 2:00 a.m. on the second Sunday of March and ends at 2:00 a.m. on the first Sunday of November.

This year, we will be turning our clocks back on Nov. 6.

The time change may not wreak as much havoc as when DST begins since we are not losing an hour of sleep, but the loss of daylight can have a negative effect on some.

People already prone to Seasonal Affective Disorder (SAD), where the change in seasons can trigger depression, are particularly vulnerable when daylight saving ends, according to Everyday Health. They suggest using a sun lamp, adjusting your schedule to get more sunlight and taking a Vitamin D supplement to ward of some of the time change’s effects.
