Three numbers. The ones that decide the meeting.
When the world meets at work.
Read the day in both zones.
Crossing the border. Money, language, plugs.
Currency is one less thing to think about — both run on the euro (EUR). Language shifts too — German in Köln, English in Dublin. Be careful behind the wheel: Köln drives on the right, Dublin on the left.

Quick answers. Before you book the call.
What's the time difference between Köln and Dublin?
Köln is 1 hour behind Dublin. Köln runs on GMT+2 and Dublin on GMT+1. The gap can shift by an hour when either side enters or leaves daylight saving — the live clocks above always reflect the current offset.
When's the best time to schedule a meeting?
There are 7 hours where both cities are inside a 09:00–17:00 workday. Aim for the middle of that window so neither side is starting or closing out.
Does daylight saving time change the difference?
Yes, if either city observes DST. When one side shifts and the other doesn't, the gap changes by one hour. The DST badges under each clock show whether each zone is currently shifted and when the next transition lands.
How far is Köln from Dublin?
About 940 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 1h 36m, not counting airport time, winds, or routing around restricted airspace.
Can I send this meeting time as a calendar invite?
Yes. Pick a time on the slider above, open the meeting card, customize the title and duration, then download the .ics file. It imports cleanly into Google Calendar, Outlook, and Apple Calendar with the correct timezone attached.
What currency do Köln and Dublin use?
Both Germany and Ireland use the euro (EUR, €). No exchange needed when moving between the two.
How do I call Köln from Dublin?
Dial the international prefix used by your carrier (often 00), then +49, then the local number — drop any leading zero of the city or mobile code. For free calls, WhatsApp, Signal, and FaceTime work over Wi-Fi regardless of country code.
What language is spoken in Köln and Dublin?
Köln primarily speaks German; Dublin speaks English, Irish. English is widely used in business contexts in major cities of both, but written contracts may need translation.
Do Köln and Dublin drive on the same side of the road?
No. Germany drives on the right, Ireland on the left. If you're renting, expect a learning curve on the first day — especially at roundabouts and when judging the centre of the lane.
