Prague time zone: CET, CEST, clock changes and quick conversions

You have a call with a colleague in Prague, or a train at 07:12, and you want to be sure whose clock it is. The answer is short. The trouble all sits around the clock changes.

The short answer

Prague is in the Central European Time zone. In winter this is CET, which is UTC+1. In summer the clocks move one hour forward to CEST (Central European Summer Time), which is UTC+2. The same arrangement applies in Berlin, Vienna, Paris, Rome, Madrid, Warsaw and Budapest. The computer name for the zone is Europe/Prague.

Czechia follows the European Union's summer time rules and changes on the same dates as the rest of the bloc. The UK changes on the same weekends, so the one-hour gap between London and Prague holds all year.

When the clocks change

Under EU rules, summer time begins on the last Sunday in March and ends on the last Sunday in October. At 02:00 local time in March the clocks jump to 03:00, and at 03:00 in October they go back to 02:00. In 2026 the clocks go back on Sunday 25 October. In 2027 they go forward on Sunday 28 March.

The European Parliament voted in 2019 to end the seasonal change, but member states never agreed a common approach, so the clocks still change (as of 2026; check the European Commission). If you are booking far ahead, check again.

The week after a change is a quiet hazard. Phones update themselves, but the wall clock, the oven and the car dashboard often don't. In March you lose an hour, so a 06:00 train that Sunday feels like a 05:00 start.

Converting from your own city

Skip the offsets and anchor on London. Prague is one hour ahead of London all year, because both change on the same weekend. Add the rest from there.

The oddity is North America. The United States moves its clocks on different dates from Europe, so for roughly a couple of weeks in March and again around the end of October or early November the gap shifts by an hour. If you have a regular call across the Atlantic, check the calendar invite twice in those weeks.

The 24-hour clock and Czech time habits

Czechs write timetables, tickets and cinema listings on the 24-hour clock, so 18:30 is just 18:30. In speech, half past six is půl sedmé, literally "half of the seventh", because Czech names the next hour. It catches out many learners.

Dates go day, month, year, and weeks start on Monday. A shop sign reading "Po-Pá 9-18" means Monday to Friday, 9 to 18. The day abbreviations are Po (Monday), Út (Tuesday), St (Wednesday), Čt (Thursday), Pá (Friday), So (Saturday) and Ne (Sunday).

Opening hours on a door come in several styles, such as "9-17", "9:00-17:00" or "9.00 - 17.00". All mean the same. Tickets put the day first, so 12.10.2026 is 12 October, not 10 December, which matters to anyone arriving from the US.

Daylight and the seasons

Prague is far enough north for daylight to swing hard. In late June the sun sets after nine in the evening, and in late December at about four in the afternoon. Hence terraces full at ten in summer and market lights at five in winter. For the weather side of the year, the guide to Prague weather month by month and the one on the best time to visit Prague put the seasons next to each other.

Working across time zones

If you work remotely, let your calendar handle the zones; the March and October weeks cause most of the mistakes. Remote work in Prague covers the practicalities. Vienna and Berlin run on Prague time, so there is no clock to reset at the border, one reason Prague to Vienna and Prague to Berlin make easy trips.
