1. When Does Daylight Saving Time Start and End in 2026?
According to TimeAndDate.com:
-
DST (Irish Standard Time, IST) starts:
Sunday, March 29, 2026, at 01:00 AM.
Clocks go forward one hour to 02:00 AM. -
DST ends / Winter Time (Greenwich Mean Time, GMT) begins:
Sunday, October 25, 2026, at 02:00 AM.
Clocks go back one hour to 01:00 AM.
Easy way to remember:
“Last Sunday in March — move forward one hour.
Last Sunday in October — move back one hour.”
2. Time Zone Overview: IST vs GMT
| Period | Time Name | Description | UTC Offset |
|---|---|---|---|
| Summer | Irish Standard Time (IST) | Ireland’s daylight saving time | UTC+1 |
| Winter | Greenwich Mean Time (GMT) | Standard winter time | UTC+0 |
Tip:
When clocks go forward, you lose one hour of sleep.
When clocks go back, you gain one hour!
3. Why Does Ireland Change the Time?
1. Purpose — Better Use of Daylight
DST is designed to make better use of natural daylight in summer evenings, reducing electricity use and extending leisure or business hours.
2. Origin and History
The idea of daylight saving time dates back to Benjamin Franklin, but it was first widely adopted during World War I by Germany and then across Europe.
Ireland’s current system was established by the Standard Time Act of 1968 and amended in 1971, setting IST for summer and GMT for winter.
3. Debate and Controversy
While DST may help energy saving, many studies show it disrupts sleep cycles, increases accident risks, and affects productivity.
Surveys show most Europeans would prefer to abolish seasonal clock changes, but due to synchronization with the UK and EU, Ireland still follows this system.
4. Practical Tips for the 2026 Clock Change
Do Devices Change Automatically?
Yes — most smartphones, computers, and tablets update automatically if “Set time automatically” or “Use network time zone” is enabled.
However, manual devices such as wall clocks, alarm clocks, and car dashboards need to be adjusted manually.
How to Avoid Confusion
- Add a reminder in Google Calendar or iPhone Reminders for both March and October.
- Double-check times for flights, exams, meetings, and online events — especially if you communicate across time zones.
- If you live near the UK border or travel frequently, verify that your devices show the correct Irish time (GMT or IST).
5. EU Discussion: Will DST Be Abolished?
In 2018, the European Commission proposed ending seasonal clock changes, but EU countries failed to agree on a common approach.
As of late 2025, Ireland still observes daylight saving time as usual.
Future changes may depend on whether the UK or the EU adopt a unified decision.

| Summer Time Zone | Irish Standard Time (UTC+1) |
| Winter Time Zone | Greenwich Mean Time (UTC+0) |
| Main Purpose | Extend daylight hours, improve energy efficiency |
| Key Issues | Health effects, traffic safety, time synchronization |
7. Final Thoughts
In 2026, Ireland will switch to Daylight Saving Time (IST) on March 29, and return to Winter Time (GMT) on October 25.
Even though the twice-yearly change can be annoying, it remains part of Ireland’s legal and cultural rhythm — at least for now.
Pro tip:
Ask your digital assistant for help:
“Hey Siri / Hey Google, remind me to change the clock on March 29.”
