It's that time of year to fall back. Don't forget to change your clocks this weekend.

Clocks fall back one hour Sunday, November 5, 2017, at 2:00 AM and we all get an extra hour of sleep.

While most of us observe Daylight Saving Time, most of Arizona and Hawaii don't observe the change. American Samoa, Guam, Puerto Rico and the Virgin Islands don't Spring ahead or Fall back.

Daylight Saving Time begins the second Sunday in March and ends the first Sunday in November. It started during WWI to save fuel, and is still considered a financial savings today. 25 percent of all the electricity we use is for lighting and small appliances in our homes. By moving the clock ahead we use less electricity.

In addition to changing your clocks, remember to change the batteries in your smoke alarms and carbon monoxide detectors.
