Photo: Change your Clocks
At 2:00 a.m. on Sunday, March 13, Daylight Saving Time begins. You should set your clocks one hour forward. This creates more sunlight hours in the evening during months when the weather is the warmest.
Why we change the clocks:
The law that governs the use of Daylight Saving Time is the Uniform Time Act of 1966. This Act provided a standard for establishing the dates when Daylight Saving Time begins and ends in the U.S., while allowing local exemptions from its observance. States that wanted to be exempt could pass a law exempting the entire state.
States that don’t follow DST:
Not all states observe Daylight Saving Time. The states of Arizona and Hawaii do not. However, the Navajo Indian Reservation in Arizona does. In addition, American Samoa, Guam, the Northern Mariana Islands, Puerto Rico and the U.S. Virgin Islands do not observe DST.
