◊ travel essentials

Crossing the border. Money, language, plugs.

Money changes hands at the border: Tehran uses the IRR (﷼) and Christchurch uses the NZD ($). Language shifts too — Persian (Farsi) in Tehran, English in Christchurch. Be careful behind the wheel: Tehran drives on the right, Christchurch on the left.

◊ common questions

Quick answers. Before you book the call.

What's the time difference between Tehran and Christchurch?

Tehran is 8.5 hours ahead of Christchurch. Tehran runs on GMT+3:30 and Christchurch on GMT+12. 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?

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 Tehran from Christchurch?

About 15,013 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 18h 10m, 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 Tehran and Christchurch use?

Tehran uses the Iranian rial (IRR, ﷼); Christchurch uses the New Zealand dollar (NZD, $). 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 Tehran from Christchurch?

Dial the international prefix used by your carrier (often 00), then +98, 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 Tehran and Christchurch?

Tehran primarily speaks Persian (Farsi); Christchurch speaks English, Māori, New Zealand Sign Language. English is widely used in business contexts in major cities of both, but written contracts may need translation.

Do Tehran and Christchurch drive on the same side of the road?

No. Iran drives on the right, New Zealand 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.
