For review purposes, I have prepared the following quiz.

1. When we fall back, does that mean when we wake up at our usual time, the clock will say it is one hour earlier? Will it get dark earlier in the afternoon?

2. Circle the term approved by the “Associated Press Stylebook” — Daylight-Savings Time; daylight savings time; daylight saving time.

3. When do we reset our clocks?

4. Will we be starting daylight saving time (DST) this month or ending it?

5. Do all of the states observe DST?

6. Do we observe DST because farmers lobbied for it?

7. Why should cows care?

According to the “Associated Press Stylebook,” the correct usage is daylight saving time, no capitalization, no hyphen, no “s” at the end of saving.

A federal law in the U.S. specifies that daylight time (DST) applies from 2 a.m. on the second Sunday of March until 2 a.m. on the first Sunday of November in areas that do not exempt themselves. We are on DST for eight months, two thirds of the year.

In 2022, DST ends Sunday, Nov. 6, at 2 a.m. when the clock will turn backward one hour and we return to what is called local standard time. If we wake up at our usual time on Sunday, Nov. 6, say at 7 a.m., it will be 6 a.m. Fall back.

There will be more light earlier in the morning and it will get dark earlier in the evening. Sunrise and sunset will both be one hour earlier than the day before.

Marco Rubio’s Sunshine Protection Act, making DST permanent, was passed by the Senate in March 2022, but has not yet made it to the U.S. House for discussion. It would require House passage and President Biden’s signature to become law. It would take effect on Nov. 5, 2023, and we would move our clocks forward again in March and keep them there.

Most countries near the equator don’t bother with DST, because, they figure, they have enough daylight already. Arizona and Hawaii don’t observe DST either, maybe for the same reason.

The Navajo Nation — which as Tony Hillerman fans know, includes Tuba City and Window Rock — is an exception. It lies within northeastern Arizona, southeastern Utah and northwestern New Mexico. This territory observes DST, except for the Hopi Nation, enclosed within the Navajo Nation, which follows Arizona’s no DST practice, with the exception of a small fragment of the Navajo Nation which is surrounded by the Hopi Nation. When DST ends in March 2023, Arizona and the Navajo Nation will be on the same time.

Many people believe that DST was started to help out farmers, but this is not the truth. Farmers have never cared for it. I read that the barbecue and grill lobby was for it (who knew there was a barbecue and grill lobby?), as well as the golf and candy industries — candy because of Halloween — and the petroleum industry, because statistics show that DST increases petroleum consumption. Which is odd, because DST is supposed to save energy.

“Cows don’t adjust easily to changes in routine,” I read just today. Why people keep talking this way I will never understand. It makes no sense to me.

Cows are not interested in DST and local standard time. They couldn’t care less. You could put up a big clock in their barn and I guarantee they would never look at it. Digital or the old-fashioned kind with hands, it makes no difference. Call it 6 a.m. or call it 7 a.m., they just need to be milked when they’re ready.

Cranberry growers in Massachusetts complain that when they return to local standard time their work hours will be cut. Harvesters work in the cranberry bogs from dawn to dusk in the autumn. When Massachusetts goes back to local standard time and the clocks turn back an hour, the sun will set an hour earlier and they will lose that valuable daylight time. I say it’s the same with cranberries in Massachusetts as it is with cows in Michigan and Vermont. The hours between sunup and sundown don’t change because of what we call them. Start an hour earlier and quit an hour earlier, as if you never fell back at all.

Cows don’t care! Neither should we. Have a good week.
