Do the Clocks Go Back Tonight? Ireland & UK 2026 Dates

The clocks are not going back tonight — and won’t until the last Sunday in October. In 2026, that date falls on 25 October, when Ireland and the UK both shift back one hour at 2:00 AM.

Clocks go back date: Last Sunday in October · Time change: 2am to 1am · Forward date: Last Sunday in March · Ireland timezone: Irish Standard Time (IST) · UK timezone: Greenwich Mean Time (GMT) to British Summer Time (BST)

The key facts table below summarizes the verified schedule for both Ireland and the UK.

Does the clock go back tonight in Ireland?

No — the clocks are not changing tonight in Ireland. The question “do the clocks go back tonight” reflects a common pattern: people ask it whenever the weeks around October start feeling darker earlier, but the actual change happens on a fixed calendar date. In 2026, the next and only autumn clock change falls on 25 October 2026, when clocks shift back one hour at 2:00 AM, moving from Irish Standard Time back to Greenwich Mean Time (RTE lifestyle guide). This date is set by EU law, which Ireland continues to follow as a member state, meaning all EU clocks shift in unison on the last Sunday of March and October.

Current time in Ireland

Ireland currently observes Irish Standard Time (IST, UTC+1), having moved forward on 29 March 2026. This means Irish clocks are one hour ahead of GMT until the autumn change. During the summer months, sunset in Dublin typically falls after 9 PM, a benefit of the forward shift that most people notice in the evenings rather than the mornings.

Next clock change date

The next scheduled clock change in Ireland is the autumn shift on 25 October 2026 at 2:00 AM, when IST reverts to GMT (UTC+0). At this moment, the clock sequence runs 1:59 AM → 1:00 AM for one hour, effectively granting an extra hour of sleep on that Sunday morning. Wikipedia’s detailed time chronology for Ireland confirms this two-date pattern: forward on the last Sunday of March, back on the last Sunday of October (Wikipedia — Time in the Republic of Ireland).

Do the UK clocks go back tonight?

The UK operates on an identical schedule to Ireland, though it sets this independently rather than through EU law post-Brexit. The last Sunday in October is when British clocks also go back, and in 2026 that falls on 25 October 2026. Visit London, the official tourism portal for the capital, confirms the UK shift runs from 2:00 AM to 1:00 AM on that date (Visit London). So whether you’re in London, Belfast, or Dublin, the clocks move together.

UK clock change rules

UK law under the Summer Time Act 1972 sets the same formula: forward on the last Sunday of March at 1:00 AM, back on the last Sunday of October at 2:00 AM. RAC Drive’s comprehensive UK guide lists the 2026 UK forward date as 29 March 2026 and the autumn back date as 25 October 2026 at 2:00 AM to 1:00 AM (RAC Drive). One minor discrepancy appears across sources: some older or less-canonical UK references cite 1:00 AM as the shift moment rather than 2:00 AM, but the majority and most recent authoritative sources agree on 2:00 AM.

2026 schedule

The UK and Ireland 2026 clock change calendar looks like this: spring forward on 29 March 2026 (1:00 AM → 2:00 AM), then fall back on 25 October 2026 (2:00 AM → 1:00 AM). The Irish Times, reporting on the March 2026 change, noted that Ireland shifts in sync with the UK and Portugal — three jurisdictions on the same physical time zone that move as one unit (Irish Times). For 2027, the schedule shifts forward one week: clocks go back on 31 October 2027.

When do the clocks go back in 2026?

The exact date is 25 October 2026 — the last Sunday of October. The change takes effect at 2:00 AM, at which point the clocks rewind one hour to 1:00 AM. This single night defines the end of British Summer Time (BST) and Irish Standard Time (IST), reverting both countries to their standard time zones for winter. According to the RTE comprehensive guide, this is not a flexible date — it is fixed by EU directive and replicated by UK law regardless of weather or public opinion (RTE). The winter time zone for Ireland is GMT (UTC+0), and for the UK it is also GMT during this period.

Exact date and time

The verified value from the RTE source is 25 October 2026 at 2:00 AM. This is the moment the clock ticks from 1:59 AM to 1:00 AM, giving anyone awake that Sunday morning an extra hour before noon. Wikipedia’s chronology of Irish time confirms the winter transition: 02:00 IST on the last Sunday in October becomes 01:00 GMT (Wikipedia — Time in the Republic of Ireland). For anyone scheduling a flight, train, or broadcast between Ireland and another country that weekend, the one-hour overlap from 1:00 AM to 1:59 AM twice over matters.

Ireland vs UK

Ireland and the UK are synchronized — they run the same date, same hour, same direction. The only difference is legal origin: Ireland’s rule comes from EU time directives, while the UK’s rule is domestic post-Brexit legislation that happens to mirror the EU by convention. Northern Ireland, as part of the UK, follows the UK schedule. The Republic of Ireland and the UK move together without exception on these two Sundays each year.

Do I get an extra hour in bed when the clocks go back?

Yes — on the night clocks go back, you gain an hour. At 2:00 AM on 25 October 2026, the clock rewinds to 1:00 AM, which means the hour between 1:00 AM and 2:00 AM effectively repeats. If you’re asleep at that time, you experience it as waking up an hour later, giving most people an additional hour of rest before their usual alarm. The Irish Times, reporting on the March forward change, noted that the autumn shift is the opposite experience — an extra hour rather than a subtracted one (Irish Times).

What happens at 2am

On the autumn change night, clocks do not simply skip an hour — they repeat one. The sequence runs 1:59 AM, then 1:00 AM. Anyone watching a smartphone, computer, or automatically synced device will see the time jump backward. Anyone with a mechanical clock, an old alarm clock, or a non-synced device needs to manually set it back. Digital clocks in appliances like ovens, microwaves, and car dashboards may also require manual correction.

Sleep impact

The sleep gain is real but limited to one hour, and not everyone benefits equally. Shift workers on the night shift covering that transition may face scheduling complexity. Parents of young children sometimes lose the benefit because children’s sleep cycles don’t reset automatically. The health impact is generally neutral for most adults: one extra hour is welcome, but it does not offset the later sunrise that comes with shorter winter days.

Why do clocks go forward and back?

Daylight Saving Time exists to shift natural light into the hours when most people are awake. In summer, moving the clock forward extends evening daylight — after the March change, sunset in Dublin moves noticeably later, often past 8 PM. The trade-off is darker mornings. In winter, reverting to standard time restores morning light, which aligns better with typical work and school start times. The policy has roots dating back to World War I, when Germany first introduced it to save coal, and it persists across most of Europe and North America for energy and lifestyle reasons.

Purpose of daylight saving

The core purpose is energy conservation and civilian convenience. By shifting an hour of summer daylight from early morning to evening, households and businesses use less artificial lighting. RTE’s 2026 guide notes that clocks change to maximize natural light: forward in summer for evenings, back in winter for mornings (RTE). Critics argue the energy savings are marginal in the age of LED lighting and air conditioning, and that the health cost of the twice-yearly shift — disrupted circadian rhythms, increased risk of heart attacks in the days following spring forward — is underappreciated.

Spring forward, fall back

The mnemonic “spring forward, fall back” is the simplest guide: in March, clocks jump ahead one hour (losing 60 minutes of the Sunday lie-in); in October, they fall back one hour (gaining 60 minutes back). The asymmetry matters because both changes shift your effective sleep window, but only the autumn change feels like a gift to tired people. The RAC Drive UK guide describes this as a core principle for anyone managing schedules or sleep across the changeover periods (RAC Drive).

History and the EU abolition debate

The EU Parliament voted in 2019 to end bi-annual clock changes across member states, with the intended start date of 2021. However, no further legislative steps have been taken, and the proposal stalled amid disagreements about which permanent time zone each country would adopt. Ireland, as an EU member, remains bound by the current directive: last Sunday in March and October, every year. RTE’s 2026 guide notes that no DST abolition is planned in the short term despite ongoing debate (RTE).

For the UK, which is no longer an EU member, the same schedule persists by domestic law — the Summer Time Act 1972. If DST were to be permanently abolished, the UK National Grid operator has recommended returning to permanent summer time (BST year-round), which would keep evenings lighter year-round but result in very dark winter mornings. Northern Ireland, post-Brexit, still follows the UK schedule for practical reasons of cross-border alignment with the Republic.
