US Clocks Change Nov 1: Meetings From Abroad

Daylight saving time abroad catches remote workers in Brazil every year. In the United States, clocks fall back one hour at 2 a.m. local time on Sunday, November 1, 2026, according to NIST, the federal agency that keeps official US time. Brazil does not change its clocks at all, so every recurring call with a US team moves by one hour on your side starting Monday, November 2. If you work from São Paulo, Rio de Janeiro, Brasília, Fortaleza or Manaus, this guide shows exactly where your meetings land and how to fix your calendar before Monday.

The short version

• US daylight saving time ends at 2 a.m. local time on Sunday, November 1, 2026, and starts again on Sunday, March 14, 2027 (the second Sunday in March).
• Brazil ended daylight saving time by Decree 9.772 of April 25, 2019. No Brazilian clock changes in November.
• Brazil has four legal time zones: UTC-2 (Fernando de Noronha and other Atlantic islands), UTC-3 (Brasília time, including São Paulo, Rio, Brasília, Fortaleza, Salvador, Recife and Belém), UTC-4 (Manaus, Cuiabá, Campo Grande, Porto Velho and Boa Vista) and UTC-5 (Acre, including Rio Branco, and far western Amazonas).
• From November 2, a US meeting lands one hour later on every Brazilian clock.
• From São Paulo, New York goes from 1 hour behind to 2 hours behind, Chicago from 2 to 3, and Los Angeles from 4 to 5.
• Calendar apps handle the shift for you if every event was created with a time zone. Check anything created in a fixed offset, in your head, or in a shared doc.

What changes on November 1

The US rule is set by federal law and is the same every year: daylight saving time starts at 2 a.m. on the second Sunday of March and ends at 2 a.m. on the first Sunday of November. NIST's page states the 2026 dates as March 8 to November 1. At 2 a.m. on November 1, the local time becomes 1 a.m. again and that hour repeats.

Each US zone changes at 2 a.m. local time, so the East Coast moves an hour before Chicago, and so on west. For practical purposes, think of it this way: on Monday, November 2, the US workday starts one hour later on your clock everywhere in Brazil.

After the change, the US mainland zones sit at these offsets until March 14, 2027:

• Eastern (New York, Miami, Atlanta): UTC-5
• Central (Chicago, Dallas, Houston): UTC-6
• Mountain (Denver, Salt Lake City): UTC-7
• Pacific (Los Angeles, Seattle, San Francisco): UTC-8

Arizona (except the Navajo Nation) and Hawaii do not change, so a colleague in Phoenix stays at UTC-7 and one in Honolulu at UTC-10 all year.

Brazil's four time zones

The Observatório Nacional, the federal body that keeps the Hora Legal Brasileira, publishes the official zones by state. The current map comes from Law 12.876 of 2013, which restored the fourth zone for Acre and western Amazonas.

• UTC-2: Fernando de Noronha, Atol das Rocas, Trindade and Martim Vaz, and the São Pedro e São Paulo archipelago.
• UTC-3 (Brasília time): the Federal District and the states of the South, Southeast and Northeast, plus Goiás, Tocantins, Pará and Amapá. That covers São Paulo, Rio de Janeiro, Belo Horizonte, Curitiba, Florianópolis, Porto Alegre, Salvador, Recife, Fortaleza, Natal and Belém.
• UTC-4: Mato Grosso, Mato Grosso do Sul, Rondônia, Roraima and most of Amazonas, including Manaus.
• UTC-5: Acre and the far western part of Amazonas, west of the line the law draws from Tabatinga to Porto Acre.

None of the four zones observes daylight saving time. The last Brazilian summer time ran in the 2018 to 2019 season, and the 2019 decree revoked every earlier decree that set it up.

What the change means for your calendar

Here is how a standing 10 a.m. New York meeting looks from Brazilian bases. New York is on UTC-4 until November 1 and UTC-5 after.

• São Paulo, Rio de Janeiro or Brasília (UTC-3): 11 a.m. until November 1, then 12 noon.
• Fortaleza, Salvador or Recife (UTC-3): the same as São Paulo, 11 a.m. then 12 noon. The Northeast feels later in the day because the sun rises and sets early there, but the clock matches Brasília.
• Manaus or Cuiabá (UTC-4): 10 a.m. until November 1, then 11 a.m.
• Rio Branco (UTC-5): 9 a.m. until November 1, then 10 a.m., the same clock time as New York all US winter.
• Fernando de Noronha (UTC-2): 12 noon until November 1, then 1 p.m.

And a standing 9 a.m. Los Angeles stand-up, Pacific time:

• São Paulo, Rio, Brasília or Fortaleza: 1 p.m. until November 1, then 2 p.m.
• Manaus: 12 noon, then 1 p.m.
• Rio Branco: 11 a.m., then 12 noon.

A Chicago team at 9 a.m. Central lands at 11 a.m. in São Paulo before the change and 12 noon after it, and at 11 a.m. in Manaus after it.

The pattern: because Brazil never changes, US meetings move one hour later on your clock every November and one hour earlier every March. There is no odd in-between week to track, as there is between the US and countries that change on other dates.

How calendar apps handle it

Google Calendar, Outlook and Apple Calendar store each event with a time zone. A recurring meeting created by a colleague in New York is anchored to New York time, so it moves automatically on your calendar when the US changes. That is correct behavior, and it means the meeting will now sit at a new time on your day.

Where it breaks:

• Your own device time zone is wrong. If your phone or laptop is set to a manual offset instead of a named city, it will not know which rules apply. Set it to automatic, or to your city by name, such as "Sao Paulo", "Fortaleza" or "Manaus". Old devices that were never updated after 2019 sometimes still expect Brazilian summer time, so a current operating system matters.
• Events you created in your local zone for a US meeting. If you put the "Monday standup, 11 a.m." on your calendar yourself in São Paulo time, it stays at 11 a.m. while the real meeting moves to noon.
• Times written in text. Invitations, shared docs and chat messages that say "9 a.m. ET" are fine. Ones that say "9 a.m. my time" or "14:00 UTC" need a second look, because UTC never changes and your US colleagues' clocks do.
• Floating events. Some apps let you create an event with no time zone. It stays at the same clock time wherever you are, which is wrong for any call with people in other zones.
• Automations. Scheduled emails, reminders, billing runs and server jobs often run on a fixed zone. Check any that are set to US time.
• Travel inside Brazil. If you fly from São Paulo to Manaus for a week, your laptop shifts one hour back and US meetings shift with it. Let the device change zones automatically and check the first morning.

A checklist for remote workers in Brazil

Do this on Friday, October 30, or over the weekend:

1. Check your device settings. Confirm that your laptop and phone use automatic time zone, or your Brazilian city by name.
2. List your recurring US meetings for the week of November 2, and note the new local time for each.
3. Find the ones you created yourself in your local zone and edit them to the organizer's zone.
4. Recheck your working hours in Google Calendar or Outlook so scheduling assistants do not offer slots that now fall at dinner time in São Paulo or Recife.
5. Tell your team. A short note in your team channel, such as "From Nov 2 our 10 a.m. ET standup is noon for me in São Paulo," prevents the classic no-show.
6. Update client-facing booking pages (Calendly, Microsoft Bookings and similar) so your availability reflects your new overlap with the US.
7. Check your contract hours. If you are paid to cover US business hours, your local schedule shifts by one hour. A West Coast day that ended at 9 p.m. in Brasília now ends at 10 p.m. Plan meals, gym times and evening plans around it.
8. Set a reminder for March. The US changes back on Sunday, March 14, 2027. Put the reminder in your calendar now.

Small tools that help

A second clock on your screen is the most useful fix. Windows and macOS both let you add extra clocks, and time.gov shows the official US time for every zone. The Observatório Nacional's Hora Legal Brasileira page shows the official time in each of Brazil's four zones. Many people who work across zones also keep a physical reference on the desk. A dual time zone desk clock or a world time wall clock set to your team's city takes the mental math out of the morning.

If your work depends on a US phone number for two-factor codes or client calls, the time change is a good moment to check that setup too. Our guide to keeping your US mail, phone and two-factor codes working covers the options, and staying connected abroad covers local SIMs and eSIMs.

Mistakes to avoid

• Assuming Brazil changes too. Brazil observed summer time for decades, usually from October or November to February in the South, Southeast and Center-West. Old habits, old blog posts and old devices still trip people up. Since 2019 there has been none.
• Trusting a mental offset. "New York is one hour behind me" was true in October from São Paulo. From November 2 it is two. From Manaus, New York goes from the same time to one hour behind.
• Forgetting that Brazil is not one zone. A teammate in Manaus or Cuiabá is one hour behind you in Rio. A client in Rio Branco is two hours behind.
• Scheduling across the change. For any call on November 1 itself, write the zone on the invite.
• Ignoring the March flip. On March 14, 2027, US meetings move one hour earlier on your clock. An 8 a.m. Pacific call that sits at 1 p.m. in São Paulo all US winter will land at noon again.

Common questions

When does daylight saving time end in the US in 2026? At 2 a.m. local time on Sunday, November 1, 2026. Clocks go back one hour. It starts again on Sunday, March 14, 2027.

Does Brazil change its clocks? No. Decree 9.772 ended daylight saving time in Brazil in April 2019. From November 2, a US East Coast meeting is two hours later on a São Paulo clock instead of one.

How many time zones does Brazil have? Four: UTC-2 for Fernando de Noronha and other Atlantic islands, UTC-3 for Brasília time, UTC-4 for Manaus and the Center-West states of Mato Grosso and Mato Grosso do Sul, and UTC-5 for Acre and far western Amazonas.

What time is a 9 a.m. New York meeting in Manaus after November 1? 10 a.m. Manaus is on UTC-4 all year, and New York is on UTC-5 from November 1, 2026, to March 14, 2027.

Will my Google Calendar or Outlook meetings move automatically? Yes, if the event was created with a time zone, which is the default. Events you created yourself in your own zone for a US meeting will not move, so edit those.
