Daylight Saving Time Ends 2026: When Do Clocks Go Back, and Does DST Actually Save Anything?

The short answer: one more fall back, and the savings are tiny

Most of the US, Canada, the UK and the EU will still change their clocks in autumn 2026, and the energy case for doing so is weak. Studies range from about 0.3% to 0.5% daily electricity savings to a 1% increase. The bigger 2026 story is politics: western Canada has stopped changing clocks, and the US Senate holds the key.

Google searches for 'daylight savings time' in the US passed 200,000 in a week, with 'fall back 2026' and 'time change fall 2026' among the related queries. In Germany, people are already searching for the 2027 'Zeitumstellung'. The questions are the same everywhere: when exactly does it happen, and why do we still do it?

Our reading of the evidence: the clock change in autumn is mostly an inconvenience, not a danger. The spring change is the one linked to more fatal crashes and heart attacks. Energy savings are real in some studies but small, and one natural experiment found the opposite. Abolition is closer than ever in North America, but it is not law in the US or the EU as of 23 October 2026.

When do clocks go back in 2026?

The UK and EU fall back on Sunday 25 October 2026 at 01:00 UTC; the US and most of Canada fall back on Sunday 1 November 2026 at 2:00 a.m. local time. In the UK that is 2am BST becoming 1am GMT. In Germany, 3 Uhr becomes 2 Uhr. The UAE, India, China and Japan do not change at all.

The US rule comes from the Energy Policy Act of 2005, effective 2007: DST starts on the second Sunday in March and ends on the first Sunday in November, with clocks falling back from 2:00 a.m. to 1:00 a.m. Hawaii and most of Arizona stay on standard time all year.

In Europe, the rule is the last Sunday of March to the last Sunday of October, with the switch at 01:00 UTC everywhere at once. That is why London, Berlin and Paris all change in the same instant, even though local clock times differ.

Which Canadian provinces are not falling back in 2026?

British Columbia, Alberta, Manitoba, Yukon and most of Saskatchewan will not change their clocks on 1 November 2026. BC moved to permanent Pacific time (UTC-7) in March 2026, Alberta switches to Alberta Time (UTC-6) on 1 November, and Manitoba is staying on daylight time. Ontario, Quebec and the Atlantic provinces still fall back.

British Columbia passed legislation in 2019 and acted in 2026. The provincial government says clocks moved ahead on 8 March 2026, 'the final time change in British Columbia', and will not fall back on 1 November. Most of BC is now on Pacific time (PCT) at UTC-7. The East Kootenay region stays aligned with Alberta at UTC-6, while Golden makes one last change on 1 November and then uses UTC-7.

Alberta officially moves to Alberta Time (ABT), equal to UTC-6, on 1 November 2026, with no fall reset. Manitoba announced on 17 September 2026 that it will stay on daylight time permanently. Its May survey drew nearly 72,000 responses: 92% wanted to end seasonal changes, 58% preferred permanent daylight time and 34% permanent standard time.

Saskatchewan stopped changing clocks in 1966 (except Lloydminster and nearby areas) and Yukon followed in 2020. The Northwest Territories has said it will follow Alberta because they share a time zone; check local notices. Ontario passed a law in 2020 for permanent daylight time, but it only takes effect if Quebec and New York move too, so Ontario still falls back on 1 November.

How do time differences change during the gap week?

For one week, from 25 October to 1 November 2026, London is only 4 hours ahead of New York instead of 5. Europe falls back first, so transatlantic gaps shrink by an hour until the US catches up. Dubai, which never changes, moves from 3 to 4 hours ahead of London on 25 October, and from 8 to 9 hours ahead of New York on 1 November.

We calculated each pair from the official UTC offsets: UK BST (UTC+1) to GMT (UTC+0); Central Europe UTC+2 to UTC+1; US Eastern UTC-4 to UTC-5; US Pacific UTC-7 to UTC-8; Dubai UTC+4 all year; India UTC+5:30 all year; Vancouver UTC-7 and Calgary UTC-6 all year from 2026; Sydney UTC+11 since 4 October.

Who this affects most: remote workers on transatlantic teams, where a standing 9 a.m. New York call lands at 1 p.m. in London during the gap week instead of 2 p.m.; travellers booking flights that cross 25 October or 1 November; and Gulf-based staff reporting to London or New York, whose working-day overlap shifts by an hour on each date. If you are job hunting across time zones, see our look at remote jobs in 2026.

Does daylight saving time actually save energy?

Barely, and not always. The US Department of Energy found extending DST in 2007 cut electricity use by about 0.5% per day in the extra weeks, or 0.03% of the year. A meta-analysis of 44 studies found average savings of 0.34% on DST days, while an Indiana study found DST raised household electricity use by about 1%.

Energy saving is the original justification for DST, and it is the claim that has aged worst. When Congress extended DST from 2007, it required the Department of Energy to measure the effect. The 2008 report found the four extra weeks saved about 1.3 TWh of electricity. That is 0.5% per day of extended DST, but only 0.03% of the 3,900 TWh the US used in 2007. Changes in traffic and gasoline use were too small to measure.

Savings were larger in spring (about 0.50% a day over 21 days of March DST) than in the one extra November week (about 0.38% a day). Regionally, they ranged from 0.24% in the Southwest Power Pool area to 0.93% in California and Nevada.

The Indiana study is the strongest challenge to the energy claim. Indiana counties only adopted DST statewide in 2006, giving economists Matthew Kotchen and Laura Grant a natural experiment with more than 7 million monthly bills. They found DST increased residential demand by about 1%, costing Indiana households about $9 million a year, plus $1.7 million to $5.5 million a year in pollution costs. Less evening lighting was outweighed by more heating and air-conditioning.

The meta-analysis by Havranek, Herman and Irsova pooled 162 estimates from 44 studies and found a mean saving of 0.34% on DST days. Savings were larger far from the equator; subtropical regions tended to use more electricity under DST. That matters for the UAE-style climates where air-conditioning dominates.

Is the time change bad for your health and safety?

The spring change is the risky one: fatal car crashes rise about 6% in the week after clocks go forward, and one Michigan study found 25% more heart attacks on that Monday. The autumn change looks benign by comparison. The same heart study found 21% fewer heart attacks on the Tuesday after clocks fell back.

A 2020 study in Current Biology led by Josef Fritz analysed 22 years of US fatal crash data (1996 to 2017) and found about a 6% higher risk of fatal traffic accidents in the week after the spring change, which the authors equated to more than 28 deaths a year that abolishing DST could prevent.

A study presented to the American College of Cardiology in 2014 by Amneet Sandhu used Michigan hospital data from 2010 to 2013. Hospitals saw about 32 heart attack patients on a typical Monday and about eight more on the Monday after spring forward. Crucially, the total for the whole week did not change: the clock change appeared to shift when heart attacks happened, not how many occurred.

The American Academy of Sleep Medicine, backed by 21 other organisations including the National Safety Council, said in August 2020 that 'permanent, year-round standard time is the best choice' for the body clock. That puts sleep scientists at odds with the Sunshine Protection Act, which would lock in daylight time and darker winter mornings.

Does daylight saving time help the economy?

There is some evidence that evening daylight boosts spending. A JPMorgan Chase Institute study found card spending per person in Los Angeles fell 3.5% in the 30 days after DST ended, relative to Phoenix, which does not change clocks, and rose 0.9% after DST began. That supports retail arguments for later sunsets, but it is one city pair.

The JPMorgan Chase Institute (November 2016) compared Los Angeles, which observes DST, with Phoenix, which does not. Over two-thirds of the decline after DST ended came from fewer transactions rather than smaller purchases, consistent with people going out less after dark.

That finding is often cited by supporters of permanent DST, along with longer evenings for leisure and tourism. But it measures a shift in when and where people spend, not necessarily extra national output, and it does not price in sleep loss or crashes. No study we opened puts a credible net economic figure on DST as a whole.

Will the US make daylight saving time permanent?

Not yet. The House passed the Sunshine Protection Act (H.R. 139) by 308 to 117 on 14 July 2026. It was sent to the Senate Commerce Committee on 15 July, and as of early October Majority Leader John Thune said there was 'no clear path forward or consensus'. Nineteen states have laws ready to switch if Congress allows.

The House vote split across parties: Republicans 193 to 22 in favour, Democrats 114 to 95, plus one independent yes. President Trump has urged the Senate to act. The Senate companion, S. 29 by Senator Rick Scott, was introduced on 7 January 2025 with 18 cosponsors and has not left committee.

Opposition comes from both sleep scientists, who want permanent standard time, and senators from northern and rural states worried about dark winter mornings. Senator Cotton notes the US tried year-round DST in 1974 and reversed it. The Senate did pass a version by unanimous consent in March 2022, but the House never voted and the bill died.

Under current federal law, a state may stay on standard time all year (as Hawaii and most of Arizona do) but may not stay on DST all year. That is why state 'trigger laws' only take effect if Congress changes the rules.

Public opinion favours ending the switch but splits on which time to keep. An AP-NORC poll in 2025, as reported by TIME, found 47% oppose the current twice-yearly change and 12% support it; 56% favoured permanent DST and 42% permanent standard time.

Will Europe stop changing the clocks? (Zeitumstellung 2027)

Not in 2027 on current evidence. The European Parliament voted 410 to 192 (51 abstentions) on 26 March 2019 to end seasonal clock changes, but EU governments in the Council have made no progress since December 2019. Spain pushed again in October 2025, and the Commission is studying the issue further.

The Commission proposed ending clock changes on 12 September 2018, after a public consultation drew 4.6 million responses, 84% of them in favour of scrapping the switch. Parliament backed it in 2019. The file then stalled in the Council, where ministers wanted an impact assessment and a coordinated choice of time zones before agreeing.

On 20 October 2025, Spanish Prime Minister Pedro Sánchez asked EU energy ministers to end the changes from 2026, saying 'Frankly, I no longer see any reason for this'. Parliament debated the issue on 23 October 2025, and the Commission decided to undertake a further detailed study. No Council agreement exists, so the 2026 and 2027 dates stand.

The UK is outside this process. GOV.UK confirms the 2027 changes on 28 March and 31 October.

What should you do before the clocks go back?

Phones and computers update automatically, so focus on manual clocks, recurring cross-border meetings and your sleep. Check any meeting with people in another country for the 25 October to 1 November gap week, and in 2026 double-check anything involving western Canada.

1. 1
   Confirm your date

   UK and EU: night of Saturday 24 to Sunday 25 October. US and eastern Canada: night of Saturday 31 October to Sunday 1 November. BC, Alberta, Manitoba, Saskatchewan, Yukon, the UAE, India, China and Japan: no change.

2. 2
   Let devices update themselves

   Leave automatic date and time switched on for phones, laptops and smart speakers. Make sure the time zone is set by location, not a fixed offset, especially in BC and Alberta where the zone names changed in 2026.

3. 3
   Change manual clocks

   Oven, microwave, car dashboard, wall clocks, older alarm clocks, CCTV recorders, thermostats and timers on heating or lights.

4. 4
   Audit recurring meetings

   Look at every standing call with another country for the gap week. A 9 a.m. New York meeting is 1 p.m. in London from 25 October to 1 November, then returns to 2 p.m.

5. 5
   Check travel bookings

   Flights are always shown in local time. For journeys over 25 October or 1 November, recheck connection times and pick-up times.

6. 6
   Ease your sleep

   Falling back is gentler than springing forward. If you are sensitive to it, shift bedtime 15 to 20 minutes later for a few nights beforehand and get morning daylight after the change.

7. 7
   Watch the evening commute

   Sunset jumps an hour earlier overnight. Drivers, cyclists and pedestrians should plan for the first dark rush hours in the week after the change.

Claims vs evidence

Frequently asked questions

How we built this analysis

• Clock-change dates were taken from official rules: GOV.UK for the UK, the EU rule (last Sunday of March and October at 01:00 UTC) as summarised by timeanddate.com, the US Naval Observatory for the Energy Policy Act 2005 rule, and provincial government pages for BC, Alberta and Manitoba. US 2027 date: second Sunday of March 2027 = 14 March.
• Time differences (KalQLater calculation) subtract UTC offsets for each city in each period. Example: during the gap week London is UTC+0 and New York UTC-4, so 0 - (-4) = 4 hours; from 1 November New York is UTC-5, so 5 hours. Dubai (UTC+4) minus London BST (UTC+1) = 3 hours before 25 October, and 4 - 0 = 4 hours after.
• Energy share (KalQLater calculation): DOE's 1.3 TWh saving / 3,900 TWh total 2007 US electricity use = 0.033% of annual consumption.
• Cumulative state count: we summed NCSL's list of enactments by year (1, 5, 5, 5, 1, 0, 1, 1), giving 19 by 2025. NCSL excludes single-chamber resolutions in Kentucky (2022) and Ohio (2020).
• Health and energy figures are reported exactly as in each study or the organisation's summary; we did not combine studies into a single estimate because their designs and populations differ.
• Legislative status is as of 23 October 2026, based on the House Clerk roll call, LegiScan's action history and TIME's reporting of Senate leadership comments in October 2026.

Limitations

Energy and health studies cover specific places and periods (for example Indiana in the mid-2000s or Michigan hospitals in 2010–2013) and may not apply elsewhere or today. The Fritz crash estimate and Sandhu heart-attack figures were read from summaries by Sleep Review and the American College of Cardiology rather than the full papers. Canadian arrangements were new in 2026; the Northwest Territories' plans and local exceptions in BC should be checked with local authorities. Legislative status can change quickly; if the US Senate or EU Council acts after 23 October 2026, this page will be out of date. This article is general information, not legal or medical advice.
