Best Meeting Time: London to Dublin
🕐 Live Timezone Overlap: London & Dublin
London and Dublin share the same clock year-round, which makes scheduling between the two cities unusually straightforward. Both run on UTC+0 in winter and UTC+1 in summer, with identical DST changeover dates. The full 9-hour overlap, from 9am to 6pm local time in both cities, means there is no awkward early start or late finish required on either side. The main scheduling consideration is simply checking each city's public holiday calendar before confirming a date.
Time Difference: London and Dublin
London and Dublin share the same UTC offset (+1). If either city observes daylight saving on a different schedule, the offset can shift by an hour during the transition.
Both London and Dublin observe daylight saving time and move their clocks on the same weekend each spring and autumn. London operates on UTC+0 (GMT) in winter and UTC+1 (BST) in summer. Dublin mirrors this exactly, observing Irish Standard Time on the same schedule. Because both cities shift simultaneously, the time difference between London and Dublin remains zero throughout the year. There is no seasonal gap change to account for when planning calls between the two cities.
Best Times to Meet
With a 9-hour overlap running from 9am to 6pm in both London and Dublin, almost any part of the working day works. That said, lunch hours around 12:30 to 1:30pm can thin out in London, so scheduling through that slot carries some risk. Friday afternoons are worth treating cautiously: both cities see financial services teams wind down earlier than usual. Inside that 9-hour window, the cleanest slot is typically 10am to 12pm or 2pm to 4:30pm, avoiding the lunchtime gap and the Friday drift.

Tips for Scheduling Across London and Dublin
- St Patrick's Day (17 March) closes many Dublin offices; always check before booking March meetings.
- Both cities share the May Bank Holiday on the first Monday in May, so that date is off in both.
- Avoid scheduling London-Dublin calls between 12:30 and 1:30pm London time; lunch thins out attendance.
- Friday afternoon calls carry risk in both cities; financial teams in Dublin and London wind down early.
- Because both cities shift clocks on the same weekend, your saved meeting times never need seasonal adjustment.
Public Holidays and Working Weeks
Both cities follow a standard Monday to Friday working week with 9am to 6pm hours. Cross-city meetings need to account for separate public holiday calendars. Dublin observes St Patrick's Day on 17 March, when many offices close. London and Dublin share a May Bank Holiday on the first Monday in May, and both observe Christmas Day on 25 December. Always check both calendars before sending invites, as a date clear in London may be a holiday in Dublin.
