"Falling back" will never be the same.

Sunday marks last time we'll 'fall back' in October

When people set their clocks back an hour Sunday morning, it will be the last time the switch to standard time happens in October.

Next year, daylight-saving time will start earlier and end later in the year.

Under a law passed last year, daylight-saving time will start the second Sunday in March and run until the first Sunday in November, making it three weeks longer.

The law -- called the Energy Policy Act of 2005 -- is intended to make daylight last longer, thus saving energy.

Officially, the switch to standard time this year comes at 2 a.m. Sunday -- meaning an extra hour of sleep.

The shift to standard time also means darkness comes earlier in the day.

In Chicago, time will switch from Central Daylight Time to Central Standard Time. Illinois is in the same time zone as Alabama, Arkansas, Iowa, Louisiana, Minnesota, Mississippi, Missouri, Oklahoma, Wisconsin, and parts of Indiana, Kentucky and Nebraska.
