When it is 09:00 in London it is 09:00 in Dublin in January and 09:00 in July. Dublin is the same time London right now — and the difference is the same all year. This page gives the live times in both cities, the overlap between their working days, the daylight saving dates that move the difference, and the best meeting windows.

Live times in London and Dublin
The two cities side by side. The January column uses the winter offsets (London UTC+00:00, Dublin UTC+00:00); the July column uses the summer offsets (London UTC+01:00, Dublin UTC+01:00).

The world clock shows the current time in both cities live, and the individual city pages — time in London and time in Dublin — explain each city's time zone, offsets and daylight saving in full.
The time difference between London and Dublin
The difference is constant: Dublin is the same time London on every day of the year. That is the simplest case in time-zone work — the answer does not depend on the date, and a meeting set for 09:00 in London is always 09:00 in Dublin. The reason the difference never changes is that both cities observe daylight saving and change their clocks on the same dates.
To convert a time, add the difference: 09:00 in London is 09:00 in Dublin in January and 09:00 in July; 17:00 in London — the end of the working day — is 17:00 in Dublin in January and 17:00 in July. To go the other way, subtract it: 09:00 in Dublin is 09:00 in London in January. The time difference calculator does the arithmetic for any date, and the UTC to Dublin page gives the full conversion table for Dublin.
Meeting overlap between London and Dublin
The overlap is the hours when both cities are in their working day (09:00–17:00 local time). The table marks the overlapping hours in London's working day and shows what time they are in Dublin.
January
| London time | Dublin time | Both working? |
|---|---|---|
| 09:00 | 09:00 | Yes |
| 10:00 | 10:00 | Yes |
| 11:00 | 11:00 | Yes |
| 12:00 | 12:00 | Yes |
| 13:00 | 13:00 | Yes |
| 14:00 | 14:00 | Yes |
| 15:00 | 15:00 | Yes |
| 16:00 | 16:00 | Yes |
In January the overlap is 8 hours: 09:00, 10:00, 11:00, 12:00, 13:00, 14:00, 15:00, 16:00 London time. In July it is 8 hours: 09:00, 10:00, 11:00, 12:00, 13:00, 14:00, 15:00, 16:00 London time. The meeting planner finds the overlap for any two cities and any date, and the meeting time finder finds it for a whole team.
Daylight saving in London and Dublin
London observes daylight saving: in 2026 the clocks go forward on 29 March 2026 and back on 25 October 2026, moving the offset from UTC+00:00 to UTC+01:00.
Dublin observes daylight saving: in 2026 the clocks go forward on 29 March 2026 and back on 25 October 2026, moving the offset from UTC+00:00 to UTC+01:00.
The difference never changes, so there is no date on which a standing meeting moves. That does not mean the difference is the same as the difference with a third city — the difference between London and London, for example, may still move when London changes its clocks. The individual DST pages — London DST 2026 and Dublin DST 2026 — give the exact dates for each city.
Best meeting windows
The best windows in January are 09:00–17:00 in London (09:00–17:00 in Dublin). These are the hours inside both working days, so nobody is up early or late. It is a short window, so keep the meeting short and send an agenda in advance.
Calling and travel notes
When it is 09:00 in London it is 09:00 in Dublin in January; when it is 12:00 in London it is 12:00 in Dublin; when it is 17:00 in London it is 17:00 in Dublin. The difference is under 12 hours, so the two cities are usually on the same date — but check the date for late-evening and early-morning times, when the date can differ by a day. Scheduling inside Europe is the simplest case: most European countries change their clocks on the same dates (the last Sunday of March and the last Sunday of October), so the difference between London and Dublin is constant all year. The working days overlap for most of the day, and the only exceptions are the countries that have abolished the change — Iceland, Russia, Belarus and Türkiye.

The table is the whole pair in one place. The two numbers that matter most are the January and July offsets: if they are the same in both columns for a city, that city's offset never changes; if they differ, the city observes daylight saving and the difference between the cities moves with it. The individual city pages — time in London and time in Dublin — explain each city's time zone, and the DST pages — London DST 2026 and Dublin DST 2026 — give the exact change dates.
