On Sunday, Nov. 1, most Americans will push their clocks back an hour, as daylight saving time (sometimes erroneously called daylight savings time) comes to an end. In March 2021, daylight saving time will begin again and we ‘ll set our clocks forward by an hour in those regions that observe DST.
Daylight Saving Time in Other Years
|Year||DST Start (Clock Forward)||DST End (Clock Backward)|
|2020||Sunday, March 8, 2:00 am||Sunday, November 1, 2:00 am|
|2021||Sunday, March 14, 2:00 am||Sunday, November 7, 2:00 am|
|2022||Sunday, March 13, 2:00 am||Sunday, November 6, 2:00 am|
In the UK the clocks go forward 1 hour at 1am on the last Sunday in March, and back 1 hour at 2am on the last Sunday in October. The period when the clocks are 1 hour ahead is called British Summer Time (BST). There’s more daylight in the evenings and less in the mornings (sometimes called Daylight Saving Time).
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.
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.). As of March 2020, an impressive 32 states have proposed bills to end the practice of switching clocks.
Nov 7, 2021 – Daylight Saving Time Ends Sunday, November 7, 2021, 1:00:00 am local standard time instead. Sunrise and sunset will be about 1 hour earlier on Nov 7, 2021 than the day before.
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.
Why do the clocks change? It was William Willett’s idea. The proposal for Daylight Savings Time was put forward by William Willett in 1907, as he argued that we were wasting important daylight by rising at the same time in the summer as we did throughout the winter months.
In the U.S., 2:00 a.m. was originally chosen as the changeover time because it was practical and minimized disruption. Most people were at home and this was the time when the fewest trains were running.
It happens at 2 am because the change in hour backwards in Autumn means the time remains within the same day (date) to minimise confusion in those who must be up and about. It remains at 2 am when moving forward purely to maintain a regular schedule.
Has British Summer Time ever been changed since? With the war over, Britain returned to British Summer Time except for an experiment between 1968 and 1971 when the clocks went forward but were not put back.
“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.
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.
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.
