Clocks go back in Czechia this weekend: What changes beyond your alarm?

Czechia’s clocks go back in the early hours of Sunday, Oct. 25, when 3 a.m. becomes 2 a.m. The switch ends daylight saving time and returns the country to Central European Time, or CET.

For many people, that means an extra hour in bed. For overnight travelers, it can mean an extra hour at a railway station, while everyone faces an abrupt shift toward earlier sunsets by the clock.

Despite years of European debate about ending the twice-yearly adjustment, this weekend’s change is going ahead. No agreed replacement has entered into force.

The switch happens overnight from Saturday, Oct. 24, to Sunday, Oct. 25. The hour between 2 a.m. and 3 a.m. occurs twice: first under summer time, then under standard time.

Czechia moves from UTC+2 to UTC+1. Although commonly called “winter time,” CET is the country’s standard time, rather than a special winter adjustment.

Connected phones and computers generally update automatically if their date, time and location settings are correct. Wall clocks, watches, car dashboards and some household appliances may need changing manually.

The most noticeable effect comes later in the day. Prague’s sunset will be at approximately 4:50 p.m. Sunday, bringing darkness much earlier into afternoon walks, playground visits and journeys home. Sunrise also moves an hour earlier by the clock.

The timing matters for families planning outings during the following week’s school break. The Oct. 28 public holiday and autumn holidays on Oct. 29–30 fall after the change, so outdoor plans should account for the earlier dusk.

Ten overnight České dráhy services will pause at suitable stations, allowing the clocks to catch up with their timetables, the operator announced.

Without the waits, the trains would effectively run an hour ahead after the clocks reset. Morning services will depart according to standard time.

Selected services are listed below. All departure times in the table are CET, after the change.

The affected services also include the reverse Chopin service, both Canopus trains between Prague and Zurich, and both overnight Baltic Express services between Prague and Gdynia.

České dráhy says it will maintain planned connections between overnight trains at Břeclav and Bohumín.

One exception requires particular attention: the midnight IC 579 Brněnský drak from Prague will run according to summer time throughout its journey, reaching Brno at 2:49 a.m. summer time before the clocks go back.

Passengers should check their specific connection in Můj vlak or through the České dráhy live train tracker, rather than apply the same assumption to every overnight journey.

The European Commission proposed ending seasonal clock changes in 2018, and the European Parliament supported the proposal in 2019. However, member states have not agreed on a common position in the Council, leaving the existing system in place.

A central challenge is coordination: countries would need to decide whether to retain standard time or summer time permanently without creating a confusing patchwork for cross-border transport and business.

There is some renewed movement. The Commission says it has commissioned an additional study to support decision-making, expected to be completed by the end of 2026. That is a research deadline, not an agreed date for abolishing the changes.

The Commission’s current explanation also acknowledges that the energy savings originally used to justify seasonal adjustments are now generally limited.

For now, the practical instruction remains familiar: put manually adjusted clocks back one hour before bed Saturday, and check overnight travel arrangements carefully.
