When Do the Clocks Go Back in 2025? Ireland Date & Time

If you’ve ever been caught out by that one Sunday in October when an extra hour of sleep suddenly appears, you’re not alone. Ireland follows the EU daylight saving schedule, which means clocks shift twice a year — and knowing the exact date matters more than you might think. This guide gives you the confirmed 2025 date, what happens to your alarm clock, and a look ahead to 2026.

Clocks go back date 2025: 26 October 2025 · Time of change: 01:59 to 01:00 · Next forward date: 29 March 2026 · Region: Ireland and UK · Sleep impact: Gain 1 hour

Three key things to know about Ireland’s clock change: the exact date, the exact time, and what it means for your morning alarm.

Do the clocks go back in October in Ireland?

Exact date for 2025

In Ireland, clocks go back on the last Sunday of October every year. For 2025, that falls on 26 October 2025. This follows the EU-wide daylight saving schedule that Ireland has observed since joining the directive decades ago.

Time of the change

The shift happens at 01:59 local daylight time, when clocks move back one hour to 01:00. If you’re awake at that moment, you’ll technically experience the 1am hour twice — but most people are asleep and simply wake up with an extra hour on the clock.

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

How the hour shift works

Yes. When clocks go back in October, you’re effectively moving from Irish Summer Time (IST, UTC+1) back to Greenwich Mean Time (GMT, UTC+0). The result: your 1:59am becomes 1:00am, giving you that hour back. If you usually wake at 7am, you’ll feel like you’ve woken at 6am — and your body may appreciate the shift.

Impact on sleep

Sleep researchers often point out that this biannual shift disrupts circadian rhythms, but the autumn change is generally easier than the spring forward. You’re gaining an hour, not losing one. Still, if you take medication timed to specific hours, check your dosing schedule around the change.

When do the clocks go back in 2026?

2026 back date

Next year, clocks go back on 25 October 2026. The pattern stays the same — last Sunday in October — but the exact date shifts because not every October has five Sundays. Mark your calendar now so you’re not caught out.

Related forward date

Before the 2026 autumn change, clocks go forward on 29 March 2026. That marks the start of Irish Summer Time again. Mark both dates: 29 March (forward) and 25 October (back).

When do clocks change in Ireland?

Annual schedule

Ireland operates on two daylight saving transitions per year. In spring, clocks move forward one hour on the last Sunday of March. In autumn, they move back on the last Sunday of October. This has been the standard since Ireland adopted EU daylight saving rules, creating a consistent rhythm across the Republic and Northern Ireland.

Forward and back rules

The logic is simple: “spring forward, fall back.” In March, you lose an hour. In October, you gain one. The EU directive sets the specific Sundays to ensure harmonisation across member states. Ireland’s schedule matches the United Kingdom’s because both follow the same EU-derived rules.

Do I gain or lose an hour of sleep in October?

October specifics

In October, you gain an hour. This is the “Fall Back” half of the annual daylight saving cycle. Your evening will feel shorter as darkness arrives earlier, but your morning stays bright. The trade-off: lighter mornings, earlier evenings.

Practical effects

Think about how this affects your routine. If you have young children, bedtime may feel oddly early until their bodies adjust. If you work early shifts, you might notice darker conditions on your commute. Evening sports, walking, or outdoor activities shift into earlier slots naturally.

The pattern is predictable but easy to forget mid-year. Save these dates somewhere visible.

What to do with the extra hour

The extra hour gained on 26 October opens a small window. Families might use it for a Sunday outing before winter sets in. Gardeners gain an hour of morning light for autumn planting. Commuters can adjust gradually — perhaps set your alarm 15 minutes later each day in the week leading up to the change.

Whatever you choose, the practical step is simple: on Saturday night, 25 October, you don’t need to do anything. The change happens in the early hours of Sunday morning. If you have digital devices, they typically update automatically. Analogue clocks need a manual check.

Looking ahead: Ireland’s clock change schedule through 2028

The EU daylight saving schedule follows a predictable cycle. Here’s what Ireland can expect in the coming years:

Notice how the autumn date varies: it always falls on the last Sunday of October, but that Sunday shifts between the 25th and 31st depending on the calendar. Plan accordingly.
