It's that time of year again.

The clocks will be set back an hour this Sunday at 2 a.m., ending Daylight Saving Time for most of the country.

Some appliances like ovens and microwaves may need manual adjustments.

It's also advised to check smoke detector batteries and restock emergency kits.

Daylight Saving Time was first created after World War I to save fuel.

Only two states, Arizona and Hawaii, don't observe it.

The clock doesn't go back to Daylight Saving Time until March 10, 2019.

Get ready for more darkness.
