Day Light Saving 2026 in Ireland: Forward 29 March, Back 25 Oct

Every year, the same Sunday sneaks up on Irish households: the weekend you meant to sleep in, but your alarm went off an hour early. If you’re wondering whether the clocks shift in 2026—and when—you’re not alone. The good news is that Ireland’s change dates are locked in by EU directive, and they follow the same calendar each year.

Clocks go back: 25 October 2026 ·

The key dates, times, and official sources are summarized in the table below.

When do clocks change in Ireland?

Ireland follows the EU-wide Daylight Saving Time schedule, switching clocks twice a year on the last Sunday of March and the last Sunday of October. This applies uniformly to all four provinces—Connacht, Leinster, Munster, and Ulster.

Spring forward date

In 2026, clocks spring forward on Sunday, 29 March. The change happens at 1am local time, when the hour jumps from 00:59 directly to 02:00. This marks the shift from Greenwich Mean Time (GMT, UTC+00:00) to Irish Standard Time (IST, UTC+01:00).

Autumn back date

Clocks fall back on Sunday, 25 October 2026. At 2am, the hour rolls back to 1am, returning Ireland to GMT. The result is more light in the mornings as winter approaches.

What date do clocks forward in 2026?

The date is fixed: 29 March 2026. Under current EU law, all member states shift to summer time on the last Sunday in March and back to standard time on the last Sunday in October. Ireland has followed this pattern since 1916, with one break between 1968 and 1972.

Exact time of change

The spring forward happens at precisely 1am on 29 March 2026. After the change, sunrise and sunset occur roughly one hour later than the day before, extending daylight into the evenings.

Impact on daily life

The shift means brighter evenings but darker mornings. Phones and laptops typically auto-adjust, but stand-alone devices like alarm clocks, thermostats, and some older appliances may need a manual update.

Will clocks go forward in 2026 in Ireland?

Yes, clocks go forward in Ireland on 29 March 2026. This has been confirmed by multiple Irish sources, including RTE and time services that track clock changes across Europe.

Confirmation from sources

RTE, Ireland’s national broadcaster, explicitly states that clocks spring forward by one hour at 1am on the last Sunday of March. The time.now service, which aggregates international clock-change data, confirms the date as 29 March 2026.

Sunrise and sunset shifts

After the spring forward on 29 March 2026, sunrise and sunset both shift about one hour later. The practical effect: darker mornings but extended daylight in the evenings until October.

Do the clocks go back on 26 October?

No—the clocks go back on 25 October 2026, not 26 October. The correct date is the last Sunday in October, which falls on the 25th in 2026.

2026 back date

The autumn change happens at 2am on Sunday, 25 October 2026. The hour from 2:00 to 2:59 is repeated, effectively giving you an extra hour of sleep that morning.

Time adjustment

After the change, clocks revert to GMT (UTC+00:00). Sunrise comes roughly one hour earlier, giving morning commuters and schoolchildren more natural light.

Do I lose an hour of sleep on Sunday?

When clocks spring forward in March, you do lose an hour of sleep—that Sunday morning, your alarm goes off one hour earlier than usual. The flip side is that the following evenings have extra daylight.

Forward day effects

The March change briefly disrupts sleep schedules. Research from time services suggests most people adjust within a day or two. The autumn change does the opposite: you gain an hour of sleep when clocks fall back.

Preparation tips

A few days before the change, shift your bedtime 15 minutes earlier to ease the transition. Check that all non-smart devices—alarm clocks, car dashboards, thermostats—are set correctly before you go to bed on the Saturday night.

Key dates for Ireland in 2026

Two dates drive the year: 29 March when clocks move forward, and 25 October when they move back. Both follow the EU-wide directive that synchronizes the change across all member states.

Timeline of changes

Ireland first adopted Daylight Saving Time in 1916, briefly suspended the practice between 1968 and 1972, and has observed it continuously ever since. The EU attempted to end the practice in 2019 when the European Parliament voted to abolish clock changes, but no further legislative steps have been taken since that vote.
