HOLT, Fla., March 10, 2017—Sunday is the beginning of Daylight Savings Time for most of North America.
Resetting the clocks forward a hour provides an extra hour of daylight in the afternoon for the United States, Canada and Mexico’s northern border cities.
Before going to bed Saturday night, most people reset their clocks forward an hour. Those who don’t risk being late for Sunday school or other early Sunday morning appointments.
Almost as a rite of spring, some people lament the “lost” hour of sleep for the next few weeks afterwards, complaining of an internal clock adjustment to the new time.
Not every state in the United States make the time change, though. Hawaii and most of Arizona don’t make the change. Additionally, not all of Canada observes the change. Most of Saskatchewan, some locations in Quebec, Southampton Island and parts of British Columbia don’t reset their clocks.
Mexico does participate in DST, but makes the change the same time as Europe, on March 26, with the holdouts of Cancun and Hermosillo.
Lawmakers across the nation such as Wyoming, Washington, Iowa, Massachusetts and Michigan have introduced bills to abolish DST, but no changes have been made so far.
Official time change occurs at 2 a.m. locally, but most people change their clocks either the night before or the next morning.
Why 2 a.m.?
The early morning time change was a practical choice to minimize disruption for bars and early churchgoers.
“Most people were at home and this was the time when the fewest trains were running. It is late enough to minimally affect bars and restaurants, and it prevents the day from switching to yesterday, which would be confusing. It is early enough that the entire continental U.S. switches by daybreak, and the changeover occurs before most early shift workers and early churchgoers are affected,” according to WebExhibits, an online museum.
Bottom line: Don’t forget to change the clock this weekend.
