For most places on the mainland, it's the weekend to spring ahead for daylight saving time. Most Americans will get an hour less sleep but will gain an hour more of evening sunlight in the coming months.
Hawaii, most of Arizona, Puerto Rico, the Virgin Islands, American Samoa, Guam and the Northern Marianas don't make the switch.
The main impact for us is that the time difference between Hawaii and the mainland increases by an hour. It'll be a six-hour time difference to the East Coast and a three-hour time difference to the West Coast starting Sunday morning.
Officially, the change starts Sunday at 2 a.m., though most people are likely to reset their clocks before going to bed Saturday night.
It's also a good time to put new batteries in warning devices such as smoke detectors and hazard warning radios.
Daylight saving time ends Nov. 3.
