Working between London and Reykjavik
The difference between London and Reykjavik is not really a number, it's a daily rhythm. Reykjavik and London 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 London, the working day picks up earliest in the financial districts- City of London desks switch on by 07:30 for the European open. The mood in Reykjavik is its own story: Reykjavik settles into the evening at the usual hour, with the local commuter pattern setting the pace. 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. United Kingdom shifts the clock on the last Sunday of March and October; Iceland follows the EU calendar (last Sunday of March and October). When the two changes are weeks apart, the offset between London and Reykjavik 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 3h 13m 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.
