Berlin sits nine hours ahead of Los Angeles for most of the year. When it is 18:00 in Paris, it is 09:00 in San Francisco. That nine-hour gap is the baseline for scheduling between Central European Time and Pacific Standard Time, and it holds steady across winter and summer. But it breaks twice a year, and the break trips up more meetings than any other quirk of the calendar.
When is the CET to PST difference 9 hours?
The nine-hour gap applies during two long blocks of the year. From the last Sunday of October through the second Sunday of March, CET runs at UTC+1 and PST runs at UTC−8. Subtract nine hours from Berlin or Madrid and you land on the US West Coast.
When both zones shift to daylight time, the gap stays the same. Central European Summer Time moves to UTC+2. Pacific Daylight Time moves to UTC−7. The offset between them remains nine hours. From the last Sunday of March through the last Sunday of October, CEST to PDT is still a nine-hour difference.
When does the CET to PST gap shrink to 8 hours?
The United States and Europe change their clocks on different dates. The US springs forward on the second Sunday of March and falls back on the first Sunday of November. The EU springs forward on the last Sunday of March and falls back on the last Sunday of October.
The March gap
The US has already moved to PDT while Europe remains on CET. For roughly two weeks, the difference shrinks to eight hours. A 09:00 start in Berlin is 01:00 in Los Angeles, not midnight.
The October, November gap
Europe has fallen back to CET while the US is still on PDT. The eight-hour offset returns for about one week. If you do the nine-hour math in your head during either gap, you will be off by an hour.
CET to PST conversion table
| CET (winter) | PST (winter) | CEST (summer) | PDT (summer) |
|---|---|---|---|
| 00:00 | 15:00 (prev day) | 00:00 | 15:00 (prev day) |
| 06:00 | 21:00 (prev day) | 06:00 | 21:00 (prev day) |
| 09:00 | 00:00 | 09:00 | 00:00 |
| 12:00 | 03:00 | 12:00 | 03:00 |
| 15:00 | 06:00 | 15:00 | 06:00 |
| 18:00 | 09:00 | 18:00 | 09:00 |
| 21:00 | 12:00 | 21:00 | 12:00 |
What is the best time for a call between CET and PST?
The overlap is narrow. When it is 09:00 in California, it is already 18:00 in Paris. The realistic window for real-time communication runs from 16:00 to 18:00 CET, which is 08:00 to 10:00 Pacific.
Aim for 08:00 Pacific
That is 17:00 Central European Time. Push later than 10:00 Pacific and you are asking Europe to stay past 19:00.
Protect the early window
Pull earlier than 07:30 Pacific and you are asking the West Coast to start before breakfast. The sweet spot is small. Guard it.

Which cities use CET and CEST?
The Central European Time zone spans 17 IANA zones. Major cities on CET include Berlin (population 3,426,354), Madrid (3,255,944), Rome (2,318,895), Paris (2,138,551), Hamburg (1,973,896), Budapest (1,741,041), Warsaw (1,702,139), Vienna (1,691,468), Barcelona (1,686,208), Munich (1,505,005), Milan (1,371,498), Belgrade (1,273,651), Prague (1,165,581), and Köln (1,024,621).
Cities that skip daylight saving
Algiers (2,364,230) and Tunis sit in the CET metazone but stay on UTC+1 year-round. They do not observe daylight saving time. When the EU switches to CEST, these cities remain on CET and the offset between them and the rest of the zone shifts by an hour.
Why is Spain on Central European Time?
Spain switched from GMT to CET in 1940, aligning with Germany during the Franco regime, and never switched back. Geographically, much of Spain sits west of Greenwich. Solar noon in Madrid in winter falls around 13:15 to 13:30. In summer, on CEST, solar noon pushes past 14:00. That misalignment drives the country's famously late meal times and work rhythms.
When do the clocks change in the CET zone?
In 2026, clocks go forward on Sunday 29 March at 02:00 local, moving from CET (UTC+1) to CEST (UTC+2). They go back on Sunday 25 October at 03:00 local, returning to CET. In 2027, the spring change falls on Sunday 28 March and the autumn change on Sunday 31 October.
The stalled abolition proposal
The EU proposed ending seasonal clock changes in 2018, and the European Parliament voted in 2019 to abolish DST by 2021. The Council of the EU has not agreed a position, and the proposal remains stalled as of 2026. Check the European Commission's website for the current status.
How much daylight does Berlin get on the solstices and equinoxes?
Daylight varies sharply by latitude in the CET zone. Berlin sees 7 hours 39 minutes of daylight on the December solstice (21 December 2026: sunrise 08:14, sunset 15:53).
The long June days
On the June solstice (21 June 2026), daylight stretches to 16 hours 50 minutes (sunrise 04:42, sunset 21:32).
The equinoxes
The March equinox (20 March 2026) brings 12 hours 6 minutes (sunrise 06:11, sunset 18:17). The September equinox (22 September 2026) brings 12 hours 18 minutes (sunrise 06:50, sunset 19:07).
What does CET stand for?
CET stands for Central European Time, fixed at UTC+1. CEST stands for Central European Summer Time, fixed at UTC+2. Using "CET" year-round is wrong: during summer months, the correct term is CEST. Many people say "CET" when they mean "current local time in Paris or Berlin," but the distinction matters for scheduling and for systems that hardcode the abbreviation.
