Daylight Saving Time 2017: When Does It Begin?

Get ready to lose an hour of sleep. Daylight Saving Time starts Sunday, March 12, 2017.

Officially the time change is at 2 a.m. Sunday, but if you have an analog clock or one like on the microwave that doesn’t automatically change like your smartphone does, you will want to advance the time by an hour before you go to bed.

“Spring ahead” is the adage, get it?

Yes, it will be lighter longer in the day, but many of us will be back to getting to go to work when the sun's not up again.

The thought that the practice saves money and energy, the rationale behind Daylight Saving Time, is in doubt by many.

An article on the National Geographic website said a study of Indiana, which up until 2006 had counties that did and did not observe the practice, found that lighting demand did drop when Daylight Saving Time goes into effect but the savings were offset by the use of more air-conditioning.

There have even been studies that say the change in time changes biological rhythms, increasing the risk of heart attacks, the National Geographic reported.

The reality is that sunrise will be later, but so will sunset. Right now, sunrise is around 6:20 a.m. and the sun sets about 5:50 p.m.

On Sunday, the first day of Daylight Saving Time, the sun will rise around 7:12 a.m. and set close to 7 p.m.
