How to Schedule Meetings Across European Time Zones

The four business zones that matter for scheduling meetings across European time zones

For a cross-border call you need to know four offsets, not three. The familiar trio is WET, CET and EET. The fourth is a year-round UTC+3 block that does not shift for summer.

• Western European Time (WET): UTC+0 in winter, UTC+1 in summer (WEST). Used by Portugal, Ireland, the United Kingdom and the Canary Islands. Iceland stays on UTC+0 with no DST.
• Central European Time (CET): UTC+1 in winter, UTC+2 in summer (CEST). This is the de facto European business lingua franca. Most multinationals are headquartered in CET nations: Germany, France, Italy, Spain, the Netherlands, Belgium, Austria, Switzerland and Poland. See the full list of CET countries and territories.
• Eastern European Time (EET): UTC+2 in winter, UTC+3 in summer (EEST). Used by Finland, Estonia, Latvia, Lithuania, Ukraine, Romania, Bulgaria, Greece and Cyprus. See the full list of EET countries and territories.
• Year-round UTC+3: Belarus, Russia (Kaliningrad and west), and Turkey. No DST. The offset never changes.

The difference between adjacent zones is exactly one hour. WET is one hour behind CET. EET is one hour ahead of CET. No half-hour offset exists in mainland Europe.

What is the best time to schedule meetings across European time zones?

The typical cross-European window is 09:00 to 16:00 CET. Here is why.

If you schedule at 09:00 CET, the local times are:

• WET: 08:00. Normal office hours in London, Dublin and Lisbon start between 08:00 and 09:00.
• CET: 09:00. Normal office start across Germany, France and Italy.
• EET: 10:00. Normal office start in Helsinki, Athens and Bucharest.

If you schedule at 16:00 CET, the local times are:

• WET: 15:00. Still within the working day in most offices.
• CET: 16:00. Late but acceptable.
• EET: 17:00. End of the working day in Finland and Greece. Still acceptable for a finishing call.

The window shrinks if you include Nordic or Mediterranean participants who keep longer lunch breaks. In Spain and Greece, lunch can run from 13:00 to 15:00 local time, which in CET terms is 12:00 to 14:00. Avoid 12:00 to 14:00 CET for calls that include southern European colleagues.

Why do people assume everyone is on CET when scheduling meetings across European time zones?

The most frequent mistake is writing "10:00 CET" in an invitation for a colleague in Helsinki. Finland uses EET. If you send a calendar invite labelled "10:00 CET", the recipient's calendar software will typically convert it to Finnish local time. But if you type the time in the subject line or a text message, people assume you mean their local time.

The fix: state the time zone explicitly in the call title or body. Write "10:00 CET / 11:00 EET / 09:00 WET". That takes five seconds and prevents confusion.

Another common mistake: assuming the United Kingdom is on CET in summer. It is not. The UK uses British Summer Time (BST, UTC+1) from the last Sunday in March to the last Sunday in October. During that period, London is one hour behind Paris, not the same. In winter, London is on GMT (UTC+0) and Paris is on CET (UTC+1). The gap is one hour year-round. London is always one hour behind Paris.

When do clocks change for scheduling meetings across European time zones?

All EU nations and most non-EU European nations change clocks on the same dates at the same UTC moment. The switch happens at 01:00 UTC on the last Sunday of March and the last Sunday of October.

In 2026:

• Spring forward: Sunday 29 March at 01:00 UTC. Clocks go forward one hour.
• Fall back: Sunday 25 October at 01:00 UTC. Clocks go back one hour.

Because the switch is simultaneous at 01:00 UTC, the local time of the switch depends on the zone:

• WET nations switch at 01:00 local (spring) and 02:00 local (fall).
• CET nations switch at 02:00 local (spring) and 03:00 local (fall).
• EET nations switch at 03:00 local (spring) and 04:00 local (fall).

The practical effect: the one-hour gap between zones stays constant year-round. WET is always one hour behind CET. CET is always one hour behind EET. There is no seasonal shift in the gaps between European zones.

The exception: Iceland, Russia, Belarus and Turkey do not observe DST. Their offsets are constant. Iceland stays on UTC+0. Russia and Belarus stay on UTC+3. Turkey stays on UTC+3. If you schedule with a Russian colleague, Moscow is two hours ahead of CET in winter (UTC+3 vs UTC+1) and one hour ahead in summer (UTC+3 vs UTC+2). The gap shrinks by one hour in summer.

Which tools help with scheduling meetings across European time zones?

You do not need to memorise offsets. Most calendar applications (Google Calendar, Outlook, Apple Calendar) handle conversion automatically if you set the event time zone correctly.

When using a converter:

• Set the event time in the zone of the majority of participants. Usually that is CET.
• Check the local time for each participant. Pay attention to the abbreviation: CET (winter) vs CEST (summer) for Central Europe, WET (winter) vs WEST (summer) for Western Europe, EET (winter) vs EEST (summer) for Eastern Europe.
• Double-check DST status. If you are scheduling in March or October, confirm whether the date falls before or after the switch.

A quick reference: on 15 January 2026, when Brussels is on CET (UTC+1), London is one hour behind, Helsinki is one hour ahead. On 15 July 2026, when Brussels is on CEST (UTC+2), London is one hour behind, Helsinki is one hour ahead. The gaps are identical.

How do London-Paris-Helsinki and Lisbon-Berlin-Athens calls work when scheduling meetings across European time zones?

London (WET), Paris (CET), Helsinki (EET)

You need a one-hour call in January.

• 09:00 CET = 08:00 London = 10:00 Helsinki. All three participants are at work.
• 15:00 CET = 14:00 London = 16:00 Helsinki. Still works.
• The sweet spot: 10:00 to 15:00 CET.

Lisbon (WET), Berlin (CET), Athens (EET)

You need a call in July (summer time).

• 09:00 CEST = 08:00 WEST (Lisbon) = 10:00 EEST (Athens). Works.
• 16:00 CEST = 15:00 WEST (Lisbon) = 17:00 EEST (Athens). Works.
• Avoid 12:00 to 14:00 CEST if the call includes participants who take a long lunch. In Athens, that is 13:00 to 15:00 local.

What are the local times across zones when scheduling meetings across European time zones?

The gap between WET and CET is always one hour. The gap between CET and EET is always one hour. The gap between WET and EET is always two hours.
