CET to JST: 2026 Time Converter & Meeting Times
CET is Central European Time (UTC+1/+2) and JST is Japan Standard Time (UTC+9). Below is a live conversion with real-time clocks using Paris and Tokyo as representative cities. DST rules are applied automatically using IANA time zone data.

Understanding CET and JST in 2026
Time zone abbreviations like CET and JST are handy shorthand, but they hide a trap: several regions reuse the same letters, and many switch their underlying offset twice a year for daylight saving. CET maps to Central European Time and JST maps to Japan Standard Time here. Rather than memorising raw offsets, check the live conversion above -- it uses today's date and the IANA time zone database, so you never get it wrong.
For meetings with three or more locations, drop the cities into the meeting planner, which computes the live overlap with daylight saving baked in for every city at once.
Frequently Asked Questions: CET to JST
What is the time difference between CET and JST in 2026?
JST (Japan Standard Time, UTC+9) and CET (Central European Time, UTC+1/+2) are in different time zones. The exact gap is shown live above using IANA time zone data. Where a time zone observes daylight saving, the gap shifts by 1 hour seasonally -- this tool always uses the current rule.
When it's 9:00 AM CET, what time is it in JST?
Check the live hourly conversion table above. Because CET and JST may each observe DST on different schedules, the conversion depends on the current date. The green rows show when JST is in working hours.
What does CET stand for?
CET stands for Central European Time, with a UTC offset of UTC+1/+2. JST stands for Japan Standard Time, with a UTC offset of UTC+9. Note that some abbreviations like CST are reused across regions (China Standard Time vs Central Standard Time) -- always check the full time zone name to avoid confusion.
Is CET the same year-round?
No. CET (Central European Time) changes between standard and daylight time. The standard offset is UTC+1 and the daylight offset is +2.
Is JST the same year-round?
Yes. JST (Japan Standard Time) stays at UTC+9 year-round with no daylight saving adjustments.
What cities use CET and JST?
CET (Central European Time) includes Paris, France. JST (Japan Standard Time) includes Tokyo, Japan. Use the interactive meeting planner to add specific cities.
How do I convert between CET and JST for recurring meetings?
Bookmark this page and check it at the start of each season. Because at least one of these time zones observes DST, the conversion may shift by 1 hour during DST transitions. The live table above always uses the current date so you see the correct conversion.
