St. CLOUD -- It's the unofficial start of spring...Daylight Saving Time. Don't forget to set your clock ahead one hour Saturday night when you go to bed.

Daylight Saving Time begins at 2:00 a.m. on the second Sunday of March and ends at 2:00 a.m. on the first Sunday of November.

But, not every state observes Daylight Saving Time. Arizona and Hawaii don't make the time change.
