Daylight Savings Time Begins Tonight (spring ahead)
Be prepared: Don't be late for events tomorrow: At 2:00 AM local time on Sunday, the clock is moved forward to 3:00 AM.
The time change officially takes place at 2 a.m., but you don’t have to spring out of bed and move the big hand on your clock ahead an hour. The change is automatic for most smartphones, computers, tablets, and other digital devices.
If you’re still using an analog alarm clock or wall clock, you’ll probably want to move it ahead before you go to sleep on Saturday.
