Working between Dublin and London
The difference between Dublin and London is not really a number, it's a daily rhythm. London and Dublin share the same wall clock right now on the clock today, but the lived version is that the two cities share the same clock, so any meeting time that works for one works for the other. That gap, more than the raw offset, is what teams have to design around.
In Dublin, the working day picks up earliest in the financial districts- Dublin's downtown core wakes early and breaks for lunch at the usual hour. The mood in London is its own story: the Square Mile crowds Cannon Street at 08:00 and the pubs near Liverpool Street fill at 17:30. If you are scheduling between the two, the heatmap above marks the rows where both patterns line up.
Daylight saving is the other thing to keep an eye on. Ireland shifts the clock on the last Sunday of March and October; United Kingdom follows the EU calendar (last Sunday of March and October). When the two changes are weeks apart, the offset between Dublin and London is one hour off the usual for that stretch, a cliff that catches recurring calendar invites unless your calendar app rebases them automatically. Pin the meeting to a city, not an offset, and the tool handles the rest.
For travellers, the 1h 33m flight is the short version of the story. The longer one is jet lag: roughly one day of adjustment per timezone crossed, which means a trip across the 0-hour gap costs about 0 groggy days on each side. Pilots and cabin crew swear by morning sunlight and an early walk; whatever your routine, the wall-clock numbers above are the source of truth for your first morning in the new city.
