What is the time difference between Tokyo and Barcelona?

Tokyo (JST, UTC+9) is 8 hours ahead of Barcelona in winter, when Barcelona is on CET (UTC+1). In summer, when Barcelona switches to CEST (UTC+2), Tokyo is 7 hours ahead. Japan does not observe Daylight Saving Time, so the offset changes only when Spain shifts its clocks.

Does Tokyo observe Daylight Saving Time?

No. Japan abolished Daylight Saving Time in 1952 and has not used it since. Tokyo stays on JST (UTC+9) year-round.

Does Barcelona observe Daylight Saving Time?

Yes. Barcelona (Europe/Madrid) follows the EU DST schedule. Clocks go forward one hour on the last Sunday in March at 02:00 CET (moving to CEST, UTC+2), and back on the last Sunday in October at 03:00 CEST (returning to CET, UTC+1).

What are the best meeting times for Tokyo and Barcelona?

In winter (CET), Barcelona business hours 09:00-18:00 correspond to 17:00-02:00 JST in Tokyo. The most practical overlap is 09:00-10:00 Barcelona (17:00-18:00 Tokyo) — very narrow. In summer (CEST) the overlap shifts by one hour. Early morning Barcelona is the only window where Tokyo is still in a reasonable evening hour.

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 applications worldwide. Accuracy depends on your device clock being synchronized via NTP, which most devices do automatically.

What timezone abbreviation does Barcelona use?

Barcelona uses CET (Central European Time, UTC+1) from late October to late March, and CEST (Central European Summer Time, UTC+2) from late March to late October. The IANA identifier is Europe/Madrid.

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/Madrid (Barcelona) time — CET (UTC+1) in winter, CEST (UTC+2) in summer.
The UTC offsets of both cities are compared: Tokyo is 8 hours ahead in summer (CEST) and 8 hours ahead in winter (CET) — actually 7 hours in summer, 8 in winter.
Both clocks and the offset refresh every second in real time.
DST transitions for Barcelona are handled automatically — the offset flips between 7 and 8 hours each spring and autumn.
