◊ travel essentials

Crossing the border. Money, language, plugs.

Money changes hands at the border: Athens uses the EUR (€) and Kolkata uses the INR (₹). Language shifts too — Greek in Athens, English in Kolkata. Be careful behind the wheel: Athens drives on the right, Kolkata on the left.

◊ common questions

Quick answers. Before you book the call.

What's the time difference between Athens and Kolkata?

Athens is 2.5 hours ahead of Kolkata. Athens runs on GMT+3 and Kolkata on GMT+5:30. 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's the best time to schedule a meeting?

There are 6 hours where both cities are inside a 09:00–17:00 workday. Aim for the middle of that window so neither side is starting or closing out.

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 Athens from Kolkata?

About 6,313 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 7h 56m, 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 Athens and Kolkata use?

Athens uses the euro (EUR, €); Kolkata uses the Indian rupee (INR, ₹). 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 Athens from Kolkata?

Dial the international prefix used by your carrier (often 00), then +30, 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 Athens and Kolkata?

Athens primarily speaks Greek; Kolkata speaks English, Hindi, Tamil. English is widely used in business contexts in major cities of both, but written contracts may need translation.

Do Athens and Kolkata drive on the same side of the road?

No. Greece drives on the right, India 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.
