Daylight Saving Time ends on Sunday, Nov. 3, which means earlier sunsets and shorter afternoons.

The time change officially takes place at 2 a.m. The change is automatic for most smartphones, computers, tablets and other digital devices.

If you’re still using an analog alarm clock, you’ll most likely want to move it back before you go to sleep on Saturday, or when you wake up the next morning.

Not every state follows Daylight Saving Time. Most of Arizona and Hawaii, along with some U.S. territories, adhere to standard time all year long, according to the Farmers’ Almanac.
