At 2 a.m. on Sunday, Nov. 1, 2026, daylight saving time ends across Massachusetts and clocks go back one hour, to 1 a.m. That rule comes straight from federal law, which sets daylight saving time to end at 2 a.m. on the first Sunday of November each year. Most phones and computers change on their own. The microwave, the car dashboard and the wall clock in the musalla usually do not.

For most people, "fall back" means an extra hour of sleep. For Muslim families it also means something else: every prayer time on your printed calendar or masjid board moves about an hour earlier on the clock, all in one night. Here is what to expect, why it happens, and a few ways to plan for it.

The sun doesn't move, the clock does

Islamic prayer times follow the sun, not the clock. Fajr begins with the first light of dawn, Dhuhr just after the sun passes its highest point, Asr in the afternoon as shadows lengthen, Maghrib at sunset and Isha after the twilight fades. The Qur'an describes prayer as "a decree of specified times" for the believers (Surah An-Nisa, 4:103), and Surah Al-Isra (17:78) ties the daily prayers to the movement of the sun from its decline at midday to the darkness of night and the dawn.

Because the prayers are tied to the sky, nothing changes about them on Nov. 1 except the number we read on the clock. The sun sets in Boston on Sunday evening only about two minutes earlier than it did on Saturday. But because the clocks moved back an hour, the time printed next to Maghrib drops by about an hour.

What it looks like in Boston

Here are calculated times for Boston from the AlAdhan prayer-times service, using the ISNA calculation method (Fajr and Isha at 15 degrees). Your own masjid may use a different method or a different Asr calculation, so its board can differ by several minutes.

  • Sat., Oct. 31 (last day of daylight time): Fajr 5:58 a.m., sunrise 7:16 a.m., Dhuhr 12:28 p.m., Asr 3:16 p.m., Maghrib 5:39 p.m., Isha 6:57 p.m.
  • Sun., Nov. 1 (standard time): Fajr 4:59 a.m., sunrise 6:18 a.m., Dhuhr 11:28 a.m., Asr 2:15 p.m., Maghrib 4:37 p.m., Isha 5:56 p.m.
  • Fri., Nov. 6: Fajr 5:04 a.m., sunrise 6:24 a.m., Dhuhr 11:28 a.m., Asr 2:10 p.m., Maghrib 4:31 p.m., Isha 5:51 p.m.
  • Tue., Dec. 8: Fajr 5:37 a.m., sunrise 7:01 a.m., Dhuhr 11:36 a.m., Asr 1:54 p.m., Maghrib 4:11 p.m., Isha 5:36 p.m.
  • Mon., Dec. 21: Fajr 5:45 a.m., sunrise 7:10 a.m., Dhuhr 11:42 a.m., Asr 1:57 p.m., Maghrib 4:15 p.m., Isha 5:39 p.m.

Times shift a few minutes across the state. On Nov. 1 the same service puts Maghrib at about 4:41 p.m. in Worcester and 4:44 p.m. in Springfield, since the sun sets a little later the farther west you go within the same time zone.

What changes in daily life

Fajr gets easier, for now. On Oct. 31, Fajr in Boston begins around 5:58 a.m., which is close to when many people need to be up for work or school anyway. On Nov. 1 it begins around 4:59 a.m. on the clock. For people who pray at home before getting ready, the morning suddenly feels roomier. Dawn then drifts later again through December, so by Dec. 21 Fajr is back near 5:45 a.m.

Dhuhr and Asr land in the middle of the work and school day. With Asr starting around 2:10 p.m. in early November and before 2 p.m. by December, many students and workers will need to pray Asr before they leave school or the office, not after they get home. It helps to plan now: find a quiet room, talk to a manager or teacher, and check our guides to places to pray at hospitals, at Logan Airport and in downtown Boston.

Maghrib comes before most people get home. A Maghrib time of 4:31 p.m. on a Friday in early November means many commuters will still be on the train or the highway. If you drive, it can help to know a masjid or a quiet, safe spot along your route. If you break a voluntary fast, such as a Monday or Thursday fast, iftar now comes before 5 p.m.

Jumu'ah times may change. Many masajid adjust their Friday prayer times when the clocks change, and some move from one schedule to another for the winter. Check your masjid's website or social media before Friday, Nov. 6, the first Jumu'ah after the change, rather than relying on last month's time.

Your rights at work

Massachusetts law addresses religious practice at work. Under Chapter 151B, Section 4 (1A) of the General Laws, it is unlawful for an employer to require an employee to give up a religious practice their faith requires as a condition of keeping the job, and the employer must make "reasonable accommodation to the religious needs" of the employee, unless that would cause undue hardship as the law defines it. If the earlier prayer times mean you need a short break or a different lunch time, the shift in November is a good moment to raise it calmly and early. If you run into trouble, the Massachusetts Commission Against Discrimination handles complaints.

Why the earliest sunset comes before the shortest day

Here is a puzzle you can see in the times above. The shortest day of the year, the winter solstice, falls on Dec. 21. Yet the earliest Maghrib in Boston comes weeks earlier: around 4:11 p.m. in early December, while on Dec. 21 it is back to about 4:15 p.m.

The reason is that Earth's orbit around the sun is an ellipse, not a perfect circle, and Earth's axis is tilted. Together, those two facts mean "solar noon," the moment the sun is highest in the sky, does not stay at the same clock time all year. In December, solar noon drifts later each day. You can see it in the Dhuhr times, which moves from 11:28 a.m. in early November to 11:42 a.m. by Dec. 21. Astronomers call this difference between sun time and clock time the equation of time. Even as the days keep getting shorter until the solstice, the whole day is sliding later on the clock, so sunsets start getting later in early December while sunrises keep getting later into early January.

The same astronomy that explains this puzzle is what your prayer app uses every day: it works out where the sun will be in the sky over your town, then turns that into clock times.

A short checklist for the weekend

  • Saturday night, Oct. 31: set any manual clocks back one hour before bed, including the masjid clock if you help look after one.
  • Sunday, Nov. 1: check that your prayer app shows the new times. Most update automatically, but a quick look at Fajr and Maghrib confirms it.
  • Print a new calendar if you use a paper one, since October's printed times will be an hour off.
  • Check Jumu'ah times at your masjid before Friday, Nov. 6.
  • Talk to work or school about Asr and Maghrib if your schedule will now overlap with them.
