Daylight Saving Time ends this weekend. The clock is officially set back one hour at 2 a.m. Sunday.

You’ll have to set your clock back one hour before going to bed and gain an hour of sleep.

The idea behind Daylight Saving Time is to literally “save time” by making better use of daylight hours as the earth orbits around the sun. The practice of moving the clock forward one hour from Standard Time during the spring gives us more daylight during summer evenings; changing them back again in the fall grants us more light during winter mornings.
