Questions
What is the time difference between IST and CET?
4 hours 30 minutes while Berlin is on standard time (CET (UTC+1)), and 3 hours 30 minutes during daylight time (CEST (UTC+2)). India does not change its clocks, so the difference changes only when Berlin does.
Which countries use CET?
Most of mainland Europe, including Germany, France, Italy, Spain, the Netherlands, Poland and Sweden. The UK, Ireland and Portugal are an hour behind; Greece and Finland an hour ahead.
When do the clocks change?
EU summer time follows the same dates as the UK: 29 March to 25 October 2026, 28 March to 31 October 2027. The converter shows the next change for both places.
How is daylight saving worked out?
From the time-zone database built into your browser (the IANA tz database), the same data phones and calendars use, so future and past dates are correct too.
Does it need an account or send anything?
No. It runs in this page with your device's clock. Nothing is stored on a server.
