Europe's Unified DST Schedule
The European Union harmonized its daylight saving time schedule in 1996, requiring all member states to change clocks on the same dates. Before harmonization, different European countries changed their clocks on different dates, causing scheduling chaos for travelers, businesses, and broadcasters.
Current European DST Rules
- Start: Last Sunday of March at 1:00 AM UTC (clocks advance to 2:00 AM UTC)
- End: Last Sunday of October at 1:00 AM UTC (clocks go back to midnight UTC)
- This means local clocks in Central European Time (CET, UTC+1) change at 2:00 AM local, and in Eastern European Time (EET, UTC+2) at 3:00 AM local.
Which European Countries Observe DST?
All 27 EU member states observe DST. Additionally:
- United Kingdom — BST (British Summer Time, UTC+1) in summer
- Norway, Iceland, Switzerland, Albania, Bosnia, Kosovo, Moldova, Montenegro, North Macedonia, Serbia, Ukraine — all follow the same European schedule
Notable exceptions: Russia abolished DST in 2014 and stays on permanent standard time. Turkey abolished DST in 2016 and stays on permanent summer time (UTC+3 year-round).
The EU's Vote to Abolish DST
In March 2019, the European Parliament voted 410 to 192 to end mandatory biannual clock changes, with the measure to take effect in 2021. The directive would allow each member state to choose whether to remain on permanent summer time or permanent standard time. However, implementation has been repeatedly delayed because member states have not agreed on a coordinated approach. As of 2025, DST continues as before across the EU.
The Coordination Problem
The main obstacle to EU DST abolition is coordination. If neighboring countries choose different permanent times, it could create new time differences within the EU's internal market and between member states and their neighbors. For example, if Germany chose permanent summer time (UTC+2) but Poland chose permanent standard time (UTC+1), there would be a year-round one-hour difference between the two countries — when today there is none.
Summer vs. Standard: The Debate
Sleep scientists overwhelmingly recommend adopting permanent standard time, arguing that standard time is better aligned with the sun and human circadian rhythms. However, business groups and many citizens prefer permanent summer time for its extra evening daylight. This disagreement is a key reason why EU-wide abolition remains stalled.
