@Acg7707 : I didn't know until I read the article that all of Arizona does participate in daylight savings time. The only ones that do daylight savings time are the Navajo Nation. They are their own nation so they can decide as they wish.
Daylight saving time affects Arizonans even though we don't observe it. Here's how Shanti Lerner Arizona Republic Updated 6:02 am MT Oct. 28, 2021
Ever wonder why most of the United States is chasing the sun when we in Arizona are trying to duck it? It's because of daylight saving time, which in 2021 comes to an end at 2 a.m. Sunday, Nov. 7.
Being a desert state with surplus sun in the summer, Arizona doesn't practice the twice-yearly ritual of turning our clocks forward or back to adjust how much daylight we get. Let's be honest here, we do not need it to be light until 9 p.m. when it's 120 degrees out.
Still, it's important to know how daylight saving time can affect Arizonans' lives.
Here's what to know about daylight saving time in 2021. Oh, and one more thing? Drop the "s." It's daylight saving time, not daylight savings time. What is daylight saving time?
Daylight saving time is the practice whereby hundreds of millions of people in 70 countries change their clocks to gain or lose an hour on specific dates in March and November. The idea is to allow people to make better use of daylight in their area. The saying "spring forward, fall back" helps people remember which way to adjust their clocks.
When is daylight saving time in 2021?
Daylight saving time 2021 began at 2 a.m. March 14. People in places that observe it had to remember to set their clocks an hour later on that date. That's springing forward.
Daylight saving time 2021 ends at 2 a.m. Sunday, Nov. 7. On that date, clocks must be set one hour earlier. That's falling back.
Why does Arizona not follow daylight saving time?
According to www.history.com, daylight saving time was introduced during World War I, although it did not become an annual observance in the United States until 1966. But not every state wanted it. Timeanddate.com points out that in Arizona we have too much sun in summer. Why stick people with another hour of scorching daylight? So state officials decided to leave the clocks alone.
But people in part of Arizona do change their clocks. The Navajo Nation - which extends from Arizona into New Mexico and Utah - observes daylight saving time so that everyone who lives on the reservation is on the same schedule.
Hawaii is the other state that doesn't observe daylight saving time. It doesn't need the extra daylight either: Hawaii sits at a tropical latitude and there isn't much difference in the length of days in summer and winter.
How daylight saving time affects Arizona
Arizona is on Mountain Standard Time. When the rest of the country goes on daylight saving time in the spring, Arizona is three hours behind our East Coast friends and two hours behind Chicago. When daylight saving time ends in November, we're two hours behind the East Coast. Take that into account so you don't miss out on that important work call, job interview or chat with Mom and Dad. Excited to see what unfolds on "Succession" this fall? Your favorite programs might come on later than usual after Nov. 7. Check your DVR settings to make sure they will reflect daylight saving time or you might miss your shows. Arizona sports fans have to account for daylight saving time, too, especially NFL fans. In September and October, football games that start at 1 p.m. on the East Coast come on at 10 a.m. here. Once daylight saving time ends in November, those games come on at 11 a.m.
Change your clocks/Change your batteries Daylight saving is Sunday, November 7, 2021. The Pearland Fire Department would like to remind you to change your smoke alarm and carbon monoxide batteries when you change your clocks.
