Daylight Saving Time Could Become Permanent In MI: What To Know

MICHIGAN — A push to make daylight saving time permanent in 2023 cleared a major hurdle Tuesday with a unanimous vote in the U.S. Senate to send the measure to the House of Representatives. If it passes the House, it would head to President Joe Biden's desk.

There’s no assurance the House will take up the Sunshine Protection Act, but the Senate vote reflects growing pressure from states to end the twice-a-year “spring forward, fall back” ritual. Most states have some sort of legislation on the matter.

In Michigan, there are currently two bills pending that would make DST permanent. Both would make establishing year-round daylight saving time contingent on congressional approval and would take effect when DST becomes permanent in nearby states including Illinois, Indiana and Wisconsin.

Permanent DST would mean later sunsets — after 9 p.m. — in the summer in Michigan, and sunrise at a reasonable time — for example, just before 6 a.m. in June.

But in January, the sun wouldn't rise until around 9 a.m. in Michigan, or 8 a.m. in November and December. That would mean it would still be dark out when kids would be waiting for the school bus.

Sen. Marco Rubio, a Florida Republican and the chief sponsor of the bill, said in remarks on the Senate floor, "it's an idea whose time has come.”

"You'll see it's an eclectic collection of members of the United States Senate in favor of what we've just done here in the Senate, and that's to pass a bill to make daylight savings time permanent," Rubio said in remarks on the Senate floor. “Just this past weekend, we all went through that biannual ritual of changing the clock back and forth and the disruption that comes with it. And one has to ask themselves after a while, why do we keep doing it?”

Daylight saving time is observed across the United States, except in Hawaii and most of Arizona, which opted out of the Uniform Time Act of 1966, which mandated daylight saving time.

In Arizona, where the temperature can routinely reach a scorching 115 degrees, it’s a matter of retaining earlier sunsets and cooler evening temperatures. But the decision not to participate in the time adjustment isn’t universal in Arizona. Daylight saving time is observed on the Navajo Reservation, which surrounds the Hopi Reservation, which doesn’t.

Because Hawaii is far south of mainland states, with a latitude similar to Mexico City's, lawmakers there haven’t seen the need to increase the hours of daylight. The U.S. territories of American Samoa, Guam, Northern Mariana Islands, Puerto Rico and the United States Virgin Islands also don’t observe daylight saving time.

At least 22 states, including Michigan, have introduced legislation to switch to year-round daylight saving time, year-round standard time or allow voters to decide the issue, according to the National Conference of State Legislatures. Another 18 have trigger laws on the books that would take effect if Congress were to allow such a change.

Daylight saving time has been around since World War I. But it became the law of the land more than 50 years ago with the Uniform Time Act of 1966, though the exact dates — now the second Sunday in March and the first Sunday in November — have changed some over the years.

Who really benefits from the time change?

Proponents may argue that longer evenings motivate people to get out of the house. The extra hour of daylight can be used for outdoor recreation such as golf, soccer, baseball, running and more. It also benefits the tourism industry.

However, critics say the drawbacks outweigh the benefits. The time change can mess with our body clocks and circadian rhythms, making for some restless nights and sleepy days. It also is difficult to quantify the economic cost of the collective tiredness caused by daylight saving time, but studies have found a decrease in productivity after the spring transition.
