Central European Standard Time

Frequently asked questions

Common questions about CET, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].

Is CET the same across the whole region?

Not exactly. Most of the CET zone sits one hour ahead in standard time and two in summer, but Algeria and Tunisia keep year-round standard time, so check the country before scheduling noon across borders.

How many places use Central European Time?

Around 35 distinct zones—from Algiers, Tunis, Paris, Berlin, Madrid, Amsterdam, and Belgrade to remote Svalbard—share this region even if their local rules differ slightly.

When does CET switch to daylight saving?

In most CET member zones, clocks jump forward on the last Sunday in March and fall back the last Sunday in October, giving evening light from Lisbon to Budapest.

Do all CET countries observe daylight saving?

Almost all of them do. Only a couple of North African zones stay fixed year-round, avoiding the twice-yearly clock change.

Are there surprising CET countries?

Yes—Spain’s Canary Islands run their own zone, while Svalbard’s midnight sun under CET adds Arctic schedules and very long summer evenings.

Is CET ever the same as UTC?

During standard time it’s one hour ahead, so noon meetings in continental Europe feel an hour ahead of Greenwich—and in Berlin it’s never the same unless you travel westward.

Can two cities in CET be an hour apart?

Rarely, but it happens—when one zone changes its rules or skips daylight saving, you might find Algiers at the same hour as London in winter.

What countries use CET in Africa?

Algeria and Tunisia keep it year-round under different names, enabling business with Europe but without daylight saving.

Does CET make it easier to call across timezones?

Mostly yes—only offsets and a few exceptions let you swap Paris for Belgrade with stable summer time and continental timekeeping.
