Do clocks go back tonight in Ireland?
When does the next clock fall back occur?
- The next clock fall back is on Sunday, 26 October 2025 (RTÉ).
This is always the last Sunday of October, a rule coordinated across EU member states. The change happens at 2:00 a.m. local time, when clocks are set back to 1:00 a.m. GMT.
You gain an extra hour of sleep, but early morning darkness arrives sooner. For shift workers, the 2 a.m. switch means one fewer hour of weekend work if you’re on a night shift.
What time do clocks change at night?
- In Ireland, the autumn transition occurs at 2:00 a.m. – when the clock strikes 2:00 a.m., it resets to 1:00 a.m. (RTÉ).
- This applies across the Republic; Northern Ireland follows the same time but with a slightly different legal framework.
The implication: if you’re awake at 2 a.m. on 26 October, you’ll experience the same hour twice. Many modern devices update automatically, but wall clocks, ovens, and car dashboards need a manual adjustment.
The pattern: the autumn switch is the only time you get to relive a full hour of your night.
When do clocks go forward in Ireland?
Spring forward date in March
- In 2026, the spring forward occurs on Sunday, 29 March 2026 (RTÉ).
- Clocks are advanced by one hour at 1:00 a.m. to 2:00 a.m. IST.
This is always the last Sunday of March, as stipulated by EU directive. All EU member states change clocks simultaneously at 1:00 a.m. UTC (Wikipedia (general reference on DST)).
Because the switch happens at 1 a.m., the effective loss of sleep hits early risers hardest. If your day starts at 6 a.m., you’ll be waking up in darkness for a few mornings.
What time do clocks spring forward?
- At exactly 1:00 a.m. local time, clocks jump to 2:00 a.m., skipping the hour between 1:00 a.m. and 2:00 a.m. (RTÉ).
The pattern: Ireland loses that hour permanently until October. For anyone with a Saturday-night shift ending at 2 a.m., that hour simply disappears from the payroll.
Do we lose or gain an hour?
Effect of spring forward
- When clocks go forward in March, you lose an hour of sleep (RTÉ).
- The lost hour occurs between 1:00 a.m. and 2:00 a.m. local time.
Effect of fall back
- When clocks go back in October, you gain an hour (RTÉ).
- The extra hour is between 2:00 a.m. and 1:00 a.m. GMT (the 2 a.m. hour is repeated).
The catch: the spring loss often leads to a measurable increase in road traffic incidents and heart attacks in the following week, according to studies cited by Wikipedia (general reference on DST). Irish residents should plan for a few days of adjustment.
Do I get an extra hour in bed when the clocks go back?
Advice for adjusting sleep
- Yes, the autumn change gives you an extra hour in bed – the “2 a.m. to 1 a.m.” repeat effectively doubles that hour (RTÉ).
- Many people find it easier to wake up after the fall back because the morning light appears earlier relative to the clock.
For parents of young children, however, the extra hour can backfire if kids wake up at their usual internal time (now an hour earlier by the clock). Gradual adjustment over three days – shifting bedtime by 15 minutes each night – can help (Holidays-Info (calendar reference)).
The “extra hour” is only a one-off bonus. Your body clock usually re-synchronises within a few days, and the long-term effect on sleep quality is negligible for most adults.
Impact on waking time
- After the autumn change, sunrise shifts earlier by an hour, so mornings become brighter. Conversely, evenings darken earlier.
The trade-off: if you’re a morning jogger, you’ll appreciate the earlier daylight; if you rely on evening light after work, you’ll miss it.

Ireland observes daylight saving time since 1916 (Wikipedia (history of Irish time zones)). The current EU directive (2000/84/EC) standardises the schedule across member states.
History of clock changes in Ireland
- DST was first introduced in Ireland (then part of the United Kingdom) in 1916 as a wartime measure to conserve coal.
- The Republic has followed summer time continuously since the 1970s, with the current rules harmonised under EU law in 2001.
The pattern: Ireland has used DST for over a century, and despite occasional EU proposals to abolish the change, no final decision has been adopted.
The implication: Irish residents can expect the twice-yearly clock change routine to continue for the foreseeable future.

For Irish commuters and parents, the key is to mark those two Sundays in your calendar: gear up for a week of slightly disrupted sleep in spring, and enjoy the extra hour in autumn.

Frequently asked questions
Why does Ireland observe daylight saving time?
Ireland adopted DST in 1916 to save fuel during World War I, and the practice continued afterwards. Today it follows EU Directive 2000/84/EC to coordinate summer time across member states (Wikipedia (general reference on DST)).
Do all European countries change clocks at the same time?
Yes, all EU member states switch to summer time on the last Sunday of March and back to standard time on the last Sunday of October, at 1am UTC (RTÉ). Non-EU European countries may follow different schedules.
What is the history of DST in Ireland?
DST was introduced in Ireland in 1916 as a wartime measure. The current seasonal change rules have been in place since the early 1970s, harmonised under EU law in 2001 (Wikipedia (history of Irish time zones)).
How can I adjust my sleep schedule after the time change?
Gradually shift your bedtime by 15 minutes a day for three days before the change. On the morning after, get outside in natural light to reset your circadian rhythm (Holidays-Info (calendar reference)).
Do smartphones and computers update automatically?
Yes, modern devices with internet connectivity and automatic time zone settings will update at the correct time. Manual clocks, ovens, and car dashboards require you to change them.
What is the difference between GMT and IST?
GMT (Greenwich Mean Time) is Ireland’s standard time in winter. IST (Irish Summer Time) is UTC+1, used during DST from March to October (Time and Date AS (authoritative time zone data)).
Does Ireland have more than one time zone?
No, the entire Republic of Ireland uses one time zone: GMT in winter and IST in summer. Northern Ireland (UK) follows the same clock changes but is on British Summer Time (BST) during summer.
