How to Know if Daylight Savings Time Is in Effect
Daylight saving time, or DST, is an alternate time calculation that was first proposed in 1895. It is, in essence, the practice of setting clocks and timepieces ahead an hour so that afternoons and evenings have more hours of sunlight while mornings have less. According to the National Institute of Standards and Technology website, "DST is not observed in Hawaii, American Samoa, Guam, Puerto Rico, the Virgin Islands and the state of Arizona (with the exception of the Navajo Indian Reservation, which does observe DST)."
