Do you remember "Spring forward and fall back?" Tonight we shift to Daylight Savings Time.
We all move our clocks ahead one hour, unless we live in the bulk of Arizona that's not on the Navaho reservation. In Canada, the province of Saskatchewan does not observe DST.
Hawaii and our island territories - Guam, Puerto Rico, U.S. Samoa, Northern Marianas, and the U.S. Virgins - also do not observe DST. There is little day length variation near the equator.
