What is the time difference between Tokyo and Paris?

Tokyo (JST, UTC+9) is 8 hours ahead of Paris during CET (UTC+1, winter) and 7 hours ahead during CEST (UTC+2, summer). Japan does not observe Daylight Saving Time, so the offset changes only when France shifts its clocks in spring and autumn.

Does Tokyo observe Daylight Saving Time?

No. Japan abolished DST in 1952 and has not used it since. Tokyo stays on JST (UTC+9) all year. Only Paris shifts its clocks, which is why the Tokyo-Paris gap alternates between 8 and 7 hours.

When does the offset change between 8 and 7 hours?

France moves clocks forward on the last Sunday in March at 02:00 CET, entering CEST (UTC+2). At that point the Tokyo-Paris gap narrows from 8 hours to 7 hours. The gap widens back to 8 hours on the last Sunday in October at 03:00 CEST when France reverts to CET (UTC+1).

What are the best meeting times when calling from Tokyo to Paris?

In CET (winter), Tokyo at 17:00–18:00 JST corresponds to Paris at 09:00–10:00 CET — the opening of the Paris workday. In CEST (summer), Tokyo at 16:00–18:00 JST maps to Paris at 09:00–11:00 CEST. Early Tokyo afternoon is the best overlap window.

Is this tool accurate for scheduling?

Yes. It uses the IANA timezone database embedded in your browser — the same source used by operating systems and calendar apps worldwide. Accuracy depends on your device clock being synchronized via NTP, which most devices do automatically.

What is CET and CEST?

CET (Central European Time) is UTC+1, used by France and much of continental Europe in winter. CEST (Central European Summer Time) is UTC+2, observed from the last Sunday in March to the last Sunday in October. Paris switches between them automatically.

Summary

This tool displays the live current time in both Tokyo (Asia/Tokyo — JST, UTC+9 year-round, no DST) and Paris (Europe/Paris — CET in winter at UTC+1, CEST in summer at UTC+2) side by side. Because Tokyo never observes Daylight Saving Time while Paris does, the offset between the two cities changes twice a year: Tokyo is 8 hours ahead during CET and 7 hours ahead during CEST. Use this tool to schedule calls from Japan to France, coordinate remote teams, or find overlapping business hours.

How it works

Your browser reads the current moment from your device clock.
It converts that moment to Asia/Tokyo time (JST, UTC+9) using the IANA timezone database built into modern browsers.
The same moment is converted to Europe/Paris time (CET UTC+1 in winter, CEST UTC+2 in summer).
The UTC offsets of both cities are compared to calculate the exact hour difference.
All three values — Tokyo time, Paris time, and the offset — refresh every second.
When Paris switches between CET and CEST, the displayed offset adjusts automatically between +8 and +7 hours.
