◊ common questions

Quick answers. Before you book the call.

What's the time difference between Porto and Tokyo?

Porto is 8 hours ahead of Tokyo. Porto runs on GMT+1 and Tokyo on GMT+9. The gap can shift by an hour when either side enters or leaves daylight saving — the live clocks above always reflect the current offset.

When it's 10 am in Porto, what time is it in Tokyo?

10:00 am in Porto is 6:00 pm in Tokyo on the same day — evening there. The same shift applies to any hour; the quick-conversion cards and the 24-hour table above cover the full day.

When it's 3 pm in Porto, what time is it in Tokyo?

3:00 pm in Porto is 11:00 pm in Tokyo on the same day — night there. The same shift applies to any hour; the quick-conversion cards and the 24-hour table above cover the full day.

When's the best time to schedule a meeting?

Standard 09:00–17:00 workdays don't intersect. Most teams compromise with one side meeting early (before 09:00) or late (after 17:00).

Does daylight saving time change the difference?

Yes, if either city observes DST. When one side shifts and the other doesn't, the gap changes by one hour. The DST badges under each clock show whether each zone is currently shifted and when the next transition lands.

How far is Porto from Tokyo?

About 10,879 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 13h 18m, not counting airport time, winds, or routing around restricted airspace.

Can I send this meeting time as a calendar invite?

Yes. Pick a time on the slider above, open the meeting card, customize the title and duration, then download the .ics file. It imports cleanly into Google Calendar, Outlook, and Apple Calendar with the correct timezone attached.

What currency do Porto and Tokyo use?

Porto uses the euro (EUR, €); Tokyo uses the Japanese yen (JPY, ¥). Check the live rate before transferring money or paying with a card abroad — most banks add a 1–3 % FX margin on top of the mid-market rate.

How do I call Porto from Tokyo?

Dial the international prefix used by your carrier (often 00), then +351, then the local number — drop any leading zero of the city or mobile code. For free calls, WhatsApp, Signal, and FaceTime work over Wi-Fi regardless of country code.

What language is spoken in Porto and Tokyo?

Porto primarily speaks Portuguese; Tokyo speaks Japanese. English is widely used in business contexts in major cities of both, but written contracts may need translation.

Do Porto and Tokyo drive on the same side of the road?

No. Portugal drives on the right, Japan on the left. If you're renting, expect a learning curve on the first day — especially at roundabouts and when judging the centre of the lane.
