Central European Time (CET) to Japan Standard Time (JST) Time Converter
What this converter helps you do
CET to JST connects continental Europe with Japan across an eight-hour gap that shifts to seven hours during European summer time. This corridor is used by automotive manufacturers, electronics companies, trading firms, and academic institutions with partnerships spanning both regions.
Because Japan does not observe DST while Europe does, the offset changes once a year from the European side only. This converter accounts for that automatically, giving you the correct JST equivalent for any date and time you select.
How it works
The tool converts from Europe/Berlin (CET/CEST) to Asia/Tokyo (JST, always UTC+9). During CET the offset is eight hours; during CEST it narrows to seven hours.
The directional advantage: unlike US-Japan pairs, CET to JST has a manageable gap. A morning meeting in Europe falls in the late afternoon or early evening in Japan, which means real-time collaboration is feasible without anyone working at extreme hours.
Limitation: the converter handles timezone math but does not account for Japanese national holidays, European bank holidays, or company-specific schedules that might affect availability.
Practical use scenarios
- Schedule a project sync between a Munich engineering team and a Tokyo supplier.
- Align automotive production coordination calls across EU and Japanese factories.
- Plan an academic conference call between a European university and a Japanese research lab.
- Check when European market hours overlap with the Tokyo trading session.
- Coordinate a product announcement that needs simultaneous release in both regions.
Pair-specific planning notes
- Japan does not use DST. The offset is 8 hours in CET season (winter) and 7 hours in CEST season (summer). Only the European side shifts.
- The overlap window is generous compared to US-Japan: a 10 AM CET meeting is 6 PM JST in winter or 5 PM JST in summer, both within reasonable hours.
- For recurring meetings, watch the CEST transition in late March and late October. A meeting set at a fixed CET time will shift by one hour in JST terms when Europe changes clocks.

FAQ
Eight hours during CET (winter) and seven hours during CEST (summer). Japan stays fixed at UTC+9 year-round.
Yes. Unlike US-Japan, the gap is manageable. A mid-morning CET meeting falls in the early evening JST, keeping both sides within reasonable hours.
Europe observes daylight saving time but Japan does not. When Europe moves to CEST (UTC+2), the gap narrows from eight to seven hours.
