When Do Clocks Change in 2026?

Daylight Saving Time (DST) in 2026 affects over 70 countries across both hemispheres. The dates vary by country — northern hemisphere nations spring forward in March or April and fall back in October or November, while southern hemisphere countries do the reverse. And because different countries change on different dates, there are always a few weeks each year when the usual time differences between cities shift by an hour in ways that catch people off guard.

If you're reading this to figure out exactly when the clocks change where you live, scroll to your country below. If you want to understand why the dates are what they are and what the global picture looks like, read on.

United States DST 2026

In the United States, DST 2026 follows the rules established by the Energy Policy Act of 2005:

  • Spring forward (start): Sunday, March 8, 2026 at 2:00 AM local time → clocks move to 3:00 AM
  • Fall back (end): Sunday, November 1, 2026 at 2:00 AM local time → clocks move to 1:00 AM

During DST (March 8 to November 1), time zones shift: EST becomes EDT (UTC−4), CST becomes CDT (UTC−5), MST becomes MDT (UTC−6), PST becomes PDT (UTC−7). That means the US effectively operates on a different set of UTC offsets for about 8 months of the year.

States that do NOT observe DST: Arizona (except the Navajo Nation), Hawaii, Puerto Rico, Guam, US Virgin Islands, Northern Mariana Islands, American Samoa. That's 2 states plus 5 territories — which means about 5 million Americans never touch their clocks.

For the 2026 spring transition specifically, the clock change falls on March 8. This means anyone with an early morning commitment on Sunday the 8th loses an hour of sleep — alarm clocks that say 7:00 AM will feel like 6:00 AM to your body. Sleep researchers recommend going to bed 15-20 minutes earlier for a few nights leading up to the transition. In practice, most people just suffer through Monday feeling groggy and slightly irritable.

Canada DST 2026

Most Canadian provinces follow the same DST schedule as the United States:

  • Spring forward: Sunday, March 8, 2026
  • Fall back: Sunday, November 1, 2026

This alignment was deliberate — Canada synchronized with US DST dates to minimize confusion along the world's longest undefended border, where cross-border commuting and trade make time alignment genuinely important.

Exceptions: Saskatchewan does not observe DST, staying at CST (UTC−6) year-round. This means that in summer, Saskatchewan is on the same time as Alberta (which shifts to MDT/UTC−6), even though they're technically in different time zones during winter. Parts of British Columbia, particularly the Kootenay region, have voted in referendums to drop DST and adopt permanent Pacific Daylight Time, but implementation depends on alignment with neighboring US states and hasn't happened yet.

European Union DST 2026

EU member states and most of Europe follow these dates, which have been harmonized across the bloc since 1996:

  • Spring forward (CEST begins): Sunday, March 29, 2026 at 1:00 AM UTC
  • Fall back (CET resumes): Sunday, October 25, 2026 at 1:00 AM UTC

All EU countries change simultaneously by UTC time, which means local clocks change at different local times depending on the zone. In the CET zone (Germany, France, Italy, Spain), clocks jump from 2:00 AM to 3:00 AM. In the EET zone (Finland, Greece, Romania), they jump from 3:00 AM to 4:00 AM.

The EU abolition saga: The European Parliament voted overwhelmingly in 2019 to end seasonal clock changes, allowing each member state to choose permanent summer or winter time. What followed was a textbook case of European decision-making paralysis. Northern countries like Finland and Sweden, where winter darkness is extreme, worried that permanent summer time would mean sunrise after 10 AM in December. Southern countries were more relaxed about it. Eastern and western countries within the same time zone had different preferences. The proposal stalled in the Council and has been gathering dust ever since. As of 2026, everyone still changes their clocks.

United Kingdom DST 2026 (BST/GMT)

The UK maintains the same DST schedule as the EU, changing on the last Sunday of March and the last Sunday of October:

  • Spring forward (BST begins): Sunday, March 29, 2026 at 1:00 AM GMT → clocks move to 2:00 AM BST (UTC+1)
  • Fall back (GMT resumes): Sunday, October 25, 2026 at 2:00 AM BST → clocks move to 1:00 AM GMT (UTC+0)

Note the three-week gap between the US spring-forward (March 8) and the UK spring-forward (March 29). During those three weeks, the time difference between New York and London shrinks from 5 hours to 4 hours. If you have a weekly call with London colleagues, it'll be an hour off for those three weeks. This catches people every single year — I've personally missed meetings because of it more than once.

Australia DST 2026

Australia's DST runs on the Southern Hemisphere schedule, where summer is October to April:

  • Spring forward (AEDT begins): First Sunday of October → October 4, 2026 at 2:00 AM → 3:00 AM
  • Fall back (AEST resumes): First Sunday of April → April 5, 2026 at 3:00 AM → 2:00 AM

Australian states and territories that observe DST: New South Wales, Victoria, Tasmania, South Australia, Australian Capital Territory. States that don't observe DST: Queensland, Western Australia, Northern Territory.

Australia's split-DST system creates some truly confusing situations during the transition months. In summer, Sydney (AEDT, UTC+11) and Brisbane (AEST, UTC+10) are one hour apart despite being only 730 km apart on the same coastline. The border between New South Wales and Queensland becomes a timezone boundary. There are towns on the border where people cross from one timezone to another to go to work every morning. The Gold Coast (Queensland) and Tweed Heads (NSW) are essentially one continuous urban area — and yet their clocks disagree for about 6 months of the year.

New Zealand and Pacific Islands

New Zealand observes DST from the last Sunday in September to the first Sunday in April:

  • Spring forward: Sunday, September 27, 2026 at 2:00 AM → 3:00 AM NZDT (UTC+13)
  • Fall back: Sunday, April 5, 2026 at 3:00 AM → 2:00 AM NZST (UTC+12)

When New Zealand is on NZDT (UTC+13), it's one of the farthest-ahead time zones in the world — only the Chatham Islands (UTC+13:45 during DST) and the Line Islands of Kiribati (UTC+14) are ahead. New Zealand is literally among the first places to see each new day.

Most other Pacific island nations — Fiji, Tonga, Samoa, Papua New Guinea — do not observe DST, though Fiji experimented with it for a period.

Countries That Have Permanently Abolished DST

The list of countries that have recently dropped DST keeps growing:

  • Russia: Abolished DST in 2014, permanently on standard time under a decree by President Putin
  • Turkey: Moved to permanent summer time (UTC+3) in 2016 under President Erdogan
  • Brazil: Abolished DST in 2019 after studies showed negligible energy savings
  • Most of Mexico: Ended DST in 2022, though northern border states near the US still change clocks to stay aligned with American partners
  • Argentina: Has not observed DST since 2008
  • Most of Asia: China, Japan, South Korea, India, Singapore, and most of Southeast Asia have never adopted it or dropped it decades ago
  • Most of Africa: Only Morocco observes DST on the continent, and even Morocco suspends it during Ramadan

The Science of "Springing Forward"

When clocks spring forward, you "lose" one hour of sleep. That sounds minor — it's just one hour. But the research on what happens in the days following the spring transition is striking.

A study published in Current Biology found a 6% increase in fatal car accidents in the week after the spring-forward. A meta-analysis in the Journal of Clinical Sleep Medicine documented increased heart attack rates on the Monday and Tuesday following the spring transition. Workplace injury rates spike. Emergency room visits increase. Even judges hand out harsher sentences on the Monday after the spring-forward, according to a study published in Psychological Science — presumably because sleep-deprived judges are crankier.

The economic cost is estimated at approximately $434 million per year in the US alone, primarily from lost productivity. This doesn't count the harder-to-measure costs: the IT hours spent debugging timezone-related issues, the missed meetings from wrong-time calendar entries, or the simple human misery of feeling jet-lagged for a week without having gone anywhere.

The "fall back" transition in autumn is generally considered less harmful, as it adds an extra hour of sleep. But it's not without consequences — the sudden shift to earlier darkness can worsen seasonal affective disorder, and the one-hour overlap between 1:00 AM and 2:00 AM creates scheduling and logging problems in software systems.

How to Prepare for the Clock Change

Practical tips for surviving the spring-forward:

  • Shift your bedtime gradually — go to bed 15-20 minutes earlier for 3-4 nights before the transition
  • Get morning light — exposure to bright light in the morning helps reset your circadian clock faster
  • Verify your tech — smartphones and computers update automatically, but older devices, standalone alarm clocks, microwave clocks, and car dashboards usually need manual adjustment
  • Check your calendar — if you have morning meetings on the Monday after the spring-forward, double-check that your calendar apps have adjusted correctly, especially for cross-timezone meetings
  • Be extra cautious driving — the elevated accident risk is real, particularly during the Monday morning commute

Frequently Asked Questions

When do clocks change in the US in 2026?

In 2026, US clocks spring forward on Sunday, March 8 at 2:00 AM (moving to 3:00 AM) and fall back on Sunday, November 1 at 2:00 AM (moving to 1:00 AM). These dates apply to all states that observe daylight saving time.

When do clocks change in Europe in 2026?

In 2026, EU and UK clocks spring forward on Sunday, March 29 and fall back on Sunday, October 25. The EU changes at 1:00 AM UTC, while the UK changes at 1:00 AM GMT (spring) and 2:00 AM BST (autumn).

Do all countries change clocks on the same date?

No. Different countries change clocks on different dates. The US changes in early March and early November, Europe changes in late March and late October, and Southern Hemisphere countries like Australia change in October and April (their spring and autumn). This creates periods where international time differences temporarily shift.

Does Australia observe daylight saving time?

Only some Australian states observe DST. New South Wales, Victoria, South Australia, Tasmania, and the ACT observe DST from the first Sunday of October to the first Sunday of April. Queensland, Western Australia, and the Northern Territory do not observe DST.

Which countries abolished daylight saving time recently?

Brazil abolished DST in 2019, most of Mexico ended DST in 2022, Turkey moved to permanent summer time in 2016, and Russia adopted permanent standard time in 2014. The EU voted to end DST in 2019 but has not yet implemented the change.

Do you lose or gain an hour when clocks spring forward?

When clocks spring forward, you lose one hour of sleep. The clock jumps from 2:00 AM to 3:00 AM, effectively skipping an hour. When clocks fall back in autumn, you gain an hour as the clock moves from 2:00 AM back to 1:00 AM.

Why is the DST spring-forward associated with health risks?

Losing one hour of sleep during the spring-forward disrupts circadian rhythms, which research links to a 6% increase in fatal traffic accidents, measurable spikes in heart attacks, increased workplace injuries, and reduced cognitive performance lasting up to a week after the transition.
