Why Madrid Is on Berlin Time and Lisbon Is Not
Spain runs one hour ahead of its solar noon. In 1940, Francisco Franco aligned the country with Nazi Germany and moved the clocks forward. The order was never reversed. Mainland Spain has used CET (UTC+1) in winter and CEST (UTC+2) in summer ever since, while the Canary Islands stay on WET (UTC+0) and WEST (UTC+1). When it is 12:00 in Madrid, it is 11:00 in Las Palmas.
Portugal tried the same shift twice and abandoned it both times. From 1966 to 1976 and again from 1992 to 1996, the country moved to CET. Portugal returned to WET both times. The Azores sit even further west on AZOT (UTC-1) in winter and AZOST (UTC+0) in summer.
How Much Does the CET Offset Change in Summer and Winter?
CET is not a fixed number. It is a scale that moves with the seasons.
- Standard Time (CET): UTC+1 in winter
- Summer Time (CEST): UTC+2 in summer
The switch happens twice a year, always at 01:00 UTC. Local clock times differ by zone. In Paris and Brussels the change hits at 02:00. In Warsaw and Berlin it also hits at 02:00. Further east, EET countries like Athens and Helsinki change at 03:00.
On 15 January 2026, Paris is 6 hours ahead of New York, 9 hours ahead of Los Angeles, 1 hour ahead of London, and 1 hour behind Johannesburg. On 15 July 2026, Paris is still 6 hours ahead of New York and 9 hours ahead of Los Angeles, but the gap to London stays at 1 hour. London is on BST (UTC+1) while Paris is on CEST (UTC+2). Johannesburg moves to the same time as Paris in July.
The Full List of CET Countries

Germany's Three Zones Are a Legacy
Germany lists three IANA zones, but the entire country operates on Europe/Berlin. The extra entries are historical aliases, not active divisions.
The Balkans Share a Zone
Serbia, Montenegro, Slovenia, Bosnia and Herzegovina, and North Macedonia all use Europe/Belgrade. The zone is identical across borders.
Non-EU Countries That Follow the Same Clock
Several CET countries sit outside the European Union. They align with the EU DST schedule voluntarily to avoid economic disruption with neighbours.
- Norway uses CET/CEST. Svalbard (Arctic/Longyearbyen) runs the same offset despite its extreme northern latitude.
- Switzerland uses CET/CEST under Europe/Zurich.
- Liechtenstein uses CET/CEST under Europe/Vaduz.
- Andorra, Monaco, San Marino, and Vatican City all use CET/CEST. Their IANA zones are Europe/Andorra, Europe/Monaco, Europe/Rome, and Europe/Rome respectively.
These states are not bound by Directive 2000/84/EC, but they follow the same last-Sunday-of-March and last-Sunday-of-Ocober schedule.
Territories and Microstates That Break the Pattern
Several territories look like they should be on CET but are not.
- Ã…land Islands: This autonomous Finnish region uses EET/EEST (Europe/Helsinki), not CET. The database lists two zones, but the active one is UTC+2 in winter and UTC+3 in summer.
- Faroe Islands: They use WET/WEST (Atlantic/Faroe), UTC+0 in winter and UTC+1 in summer.
- Ceuta and Melilla: These Spanish cities on the North African coast use CET/CEST (Africa/Ceuta), matching mainland Spain rather than the Canary Islands.
- Gibraltar: Uses CET/CEST (Europe/Gibraltar), aligned with Spain.
- Guernsey, Jersey, Isle of Man: These Crown Dependencies use GMT/BST (Europe/Guernsey, Europe/Jersey, Europe/Isle_of_Man), not CET. They follow UK time.
How CET Sits Between Its Neighbours
CET occupies the middle of Europe's three main time bands.
To the West: WET (UTC+0)
Portugal, the UK, and Ireland run on WET in winter and WEST (UTC+1) in summer. London is 1 hour behind Paris in January. In July, the gap stays at 1 hour because both cities move forward by one hour.
To the East: EET (UTC+2)
Greece, Romania, Finland, Estonia, Latvia, Lithuania, Bulgaria, Cyprus, Moldova, and Ukraine use EET in winter and EEST (UTC+3) in summer. Athens is 1 hour ahead of Paris year-round. The CET/EET border cuts through the Balkans: Poland and Slovakia are on CET, while Lithuania and Romania are on EET.
The Permanent Exceptions
Belarus and Turkey stay on UTC+3 year-round with no DST. Russia spans 27 zones from UTC+2 (Kaliningrad) to UTC+12 (Anadyr) and does not change clocks. Iceland uses UTC+0 year-round despite sitting at roughly 22°W, which would be UTC-2 solar time.
When Do CET Countries Change Their Clocks Next?
Sunday29 March2026
At02:00 local time, clocks jump forward60 minutes to03:00. CET (UTC+1) becomes CEST (UTC+2). This is the spring forward for every country on this list.
Sunday25 October2026
At03:00 local time, clocks fall back60 minutes to02:00. CEST (UTC+2) reverts to CET (UTC+1).
Sunday28 March2027
At02:00 local time, clocks go forward60 minutes to03:00. CET becomes CEST again.
Sunday31 October2027
At03:00 local time, clocks go back60 minutes to02:00. CEST becomes CET.
The switch is simultaneous across all observing countries at01:00 UTC. For New York callers, the gap is6 hours in both winter and summer, but the US changes its clocks on different dates. The gap can briefly stretch to7 hours in March and compress to5 hours in October. Check the exact dates before scheduling.
Will CET Countries Ever Stop Changing Their Clocks?
In2018 the European Commission proposed ending seasonal clock changes after a public consultation drew4.6 million responses, with84 percent favouring abolition. The European Parliament voted in March2019 to end DST by2021. The Council of the EU has not agreed a position. As of2026, the proposal is stalled with no implementation date. If it ever passes, each member state would choose permanent standard time or permanent summer time, creating a patchwork of offsets across the continent.

What CET Means for Daily Life Across the Zone
Business Hours Vary North to South
Offices in Germanic and Nordic countries typically open08:00 to09:00 and close16:00 to17:00. Mediterranean offices start later,09:00 to10:00, and run until18:00 or19:00. Banks generally operate08:30 to16:30 Monday to Friday, with a lunch closure in southern Europe from roughly13:00 to14:30. Government offices tend to open08:00 to09:00 and close15:00 to16:00.
Sunday Trading Splits the Map
Germany, Austria, Switzerland, and Norway restrict Sunday shopping. The UK, Ireland, the Netherlands, and most of Scandinavia allow it. France, Spain, and Italy fall somewhere in between with partial restrictions.
Meal Times Create Cross-Border Friction
Lunch in the north sits at11:30 to13:00. In the south it runs13:00 to15:00. Dinner in Norway or the Netherlands starts17:00 to19:00. In Spain or Italy it begins20:00 to22:00. A17:00 conference call from Amsterdam lands during a Madrid lunch break. A21:00 dinner invitation in Rome conflicts with a Stockholm bedtime.
School Hours Follow the Same Split
Primary schools in Germany and Austria run08:00 to12:00 or13:00. In France, Spain, and the UK the day stretches to15:30 or16:30. Southern schools often include a one to two-hour lunch break. Northern schools keep it to30 to60 minutes.
Market Overlaps Drive Trading
The London Stock Exchange opens08:00 to16:30 GMT/BST. Euronext (Paris, Amsterdam, Brussels, Lisbon, Dublin) and Deutsche Börse (Frankfurt) run09:00 to17:30 CET/CEST. The overlap window is08:00 to16:30 GMT in winter, which equals09:00 to17:30 CET. In summer the same local hours apply because both zones shift forward together.
Broadcasting Syncs on CET
The Eurovision Song Contest broadcasts at21:00 CEST across all participating countries. UEFA Champions League kickoffs typically land at21:00 CET/CEST, which means20:00 in London,22:00 in Athens, and23:00 in Moscow. Formula1 European races start around14:00 to15:00 local time and ripple outward from there.
DST Switch Weekends Disrupt Transport
Fewer trains run on switch night. Airlines adjust timetables. The spring forward costs an hour of sleep. The fall back adds one. Nordic cities like Tromsø experience polar night from November to January regardless of the clock, compressing all activity into a narrow window of twilight.
