All states but Hawaii and Arizona (except for the Navajo Nation) observe DST. The territories of American Samoa, Guam, the Northern Mariana Islands, Puerto Rico and the U.S. Virgin Islands also do not observe DST.
At present, daylight saving time ends at 2 a.m. local time on Nov. 1, 2020, and begins again at 2 a.m. on Sunday, March 14, 2021.
Daylight saving time then ends on the first Sunday in November, when clocks are moved back an hour at 2 a.m. local daylight time (so they will then read 1 a.m. local standard time). In 2020, DST will began on March 8 and ends on Nov. 1 in the U.S., when you’ll set the clock back an hour and the cycle will begin again.
Today, most Americans spring forward (turn clocks ahead and lose an hour) on the second Sunday in March (at 2:00 A.M. ) and fall back (turn clocks back and gain an hour) on the first Sunday in November (at 2:00 A.M. ).
The main purpose of Daylight Saving Time (called ” Summer Time” in many places in the world) is to make better use of daylight. We change our clocks during the summer months to move an hour of daylight from the morning to the evening.
“However, without DST, sunrise that same day would be 8:35 a.m., which means morning services would not finish until 9:15 a.m.” This would make it a challenge for religious Jews and Muslims who work nine to five to attend services and get to work on time.
Absent DST, for eight months per year our days would not be structured to enjoy the most sunlight possible. So during the spring, summer, and early autumn, we tweak it, just a bit, so that there’s more sunlight in the evening. In the winter, we abandon DST, because there just isn’t enough sunlight to make a difference.
Things would get weird if we didn’t. If we kept daylight saving time all year: If we observed standard time all year, a lot of your summer evening activities would fall in darkness. The sun would come up much earlier, the earliest being 5:27 a.m. in the middle of summer, but the latest sunset would only be 7:27 p.m.
Pro: Longer Evenings So, when we spring forward an hour in spring, we add one hour of natural daylight to our afternoon schedule. Proponents of DST argue that longer evenings motivate people to get out of the house. The extra hour of daylight can be used for outdoor recreation like golf, soccer, baseball, running, etc.
Congress gives states two options: to either opt out of DST entirely or to switch to DST the second Sunday in March. Some states require legislation while others require executive action such as a governor’s executive order.
You might get an “extra” hour of sleep that day, but it will also begin to get darker earlier in the day. The amount of daylight will shorten each day until the winter solstice on Dec. 21. Daylight saving time begins again March 14, when clocks “spring forward.”
In spring 2021 the clocks go forward on 28 March at 1am. In 2020 they went forward on 29 March. The clocks change on the last Sunday of March, moving forward by one hour.
Why doesn’t Arizona change? According to an Arizona Republic editorial from 1969, the reason was the state’s extreme heat. If Arizona were to observe Daylight Saving Time, the sun would stay out until 9 p.m. in the summer (instead of 8 p.m., like it does currently).
