On Sunday morning, turn your clocks back an hour.
Daylight saving time means an extra 60 minutes of sleep for most people in the U.S.
The change officially happens at 2 a.m. on Sunday.
Most cell phones and computers will reset their clocks automatically, but clocks that are not connected to the internet will need to be set an hour behind before you fall asleep Saturday.
According to federal law, the time change happens at 2 a.m. on the second Sunday of March, where people turn their clocks forward and hour; and at 2 a.m. on the first Sunday of November, where people turn their clocks back an hour.
Arizona does not observe daylight saving time.
