Convert a specific time from JST to CET
Pick any time and date to convert it both ways. The conversion runs in your browser against the real zone rules, so a date inside a daylight saving period gets that period's offset rather than today's.
What is the time difference between JST and CET?
Central European Time is 7 hours behind Japan Standard Time. To go from JST to CET you subtract 7 hours. That gap is not fixed. Across 2026 the distance between these two zones takes 2 different values, from 7 hours to 8 hours, because Central European moves its clocks and Japan does not. This page recomputes it rather than assuming.
JST to CET conversion table
Every hour of Friday, September 25, 2026 in Japan, with the matching reading in Central European. 7 of the 24 hours land on a different calendar date in Central European, which is the part people get wrong when they schedule across this pair.

What are the best hours to schedule a call between JST and CET?
1 hour of the standard 9:00 am to 5:00 pm working day line up in both zones, from 4:00 pm JST to 5:00 pm JST. In Central European that window reads 9:00 am to 10:00 am. Outside it, one side is either not yet at their desk or already gone.
| JST | CET | Working hours | Note |
|---|---|---|---|
| 4:00 pm | 9:00 am | both sides | afternoon in Japan, mid morning in Central European |
Does daylight saving change JST to CET?
Japan Standard Time does not move its clocks at all, so its UTC+9 offset holds every day of the year.
Central European Time is currently on CEST and changes next on Sunday, October 25, 2026, when the clock falls back from 2:59 am to 2:00 am and the offset moves from UTC+2 to UTC+1.
Because the two sides do not move together, the answer to this conversion changes during the year. For part of the year the gap is 7 hours and for the rest it is 8 hours. The table above is built for today, not for an average day.
Is JST ahead of or behind CET?
JST is ahead of CET by 7 hours: when it is 12:00 pm in Japan, it is 5:00 am in Central European. One wrinkle worth knowing: CET and CEST are two names for the same zone, not two zones. Central European Time reads CET in winter and CEST in summer. When somebody types "jst to cet" they nearly always mean the zone rather than the literal winter offset, so this page resolves JST to Asia/Tokyo and CET to Europe/Paris and applies whichever offset is genuinely in force on the day.
Japan Standard Time covers Tokyo, Osaka and the whole of Japan. Central European Time covers Paris, Berlin, Madrid, Rome and Amsterdam. The identifiers behind them are Asia/Tokyo and Europe/Paris, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
