DUBLIN/CORK, IRELAND – Ireland will officially conclude Daylight Saving Time (DST) for the year 2025 on Sunday, October 26th, by turning the clocks back by one hour. This seasonal shift, often remembered by the phrase “Fall Back,” marks the return to Greenwich Mean Time (GMT), or local standard time.
The Exact Time of the Change
The clocks will officially retreat one hour at 2:00 AM on Sunday, October 26th. All clocks in the Republic of Ireland will revert to 1:00 AM.
- When: Sunday, October 26, 2025
- Action: Clocks move from 2:00 AM to 1:00 AM
- Result: A welcome extra hour is gained for the day.
Cork Jazz Festival Connection
The time change falls on the October Bank Holiday Weekend, which is traditionally the climax of the famous Guinness Cork Jazz Festival (scheduled for October 23rd–27th, 2025). Patrons and performers enjoying the last night of the four-day festival will benefit from the extra hour, whether for a longer sleep-in or an extended night of music and festivity.
Seasonal Impact and Auto-Adjust
The primary effect of the change will be a noticeable shift in daylight hours:
- Mornings will immediately become brighter.
- Evenings will become significantly darker earlier. For instance, sunset on October 26th will occur around 5:04 PM, making the transition into the gloomier winter months more abrupt.
For most people, modern technology handles the change automatically. Smartphones, laptops, and internet-connected devices will adjust themselves. Only traditional wall clocks, watches, and older car clocks will need to be manually reset.
