◊ travel essentials

Crossing the border. Money, language, plugs.

Money changes hands at the border: Reykjavík uses the ISK (kr) and St. Louis uses the USD ($). Language shifts too — Icelandic in Reykjavík, English in St. Louis. Cars drive on the right in both, so rentals feel familiar.

◊ common questions

Quick answers. Before you book the call.

What's the time difference between Reykjavík and St. Louis?

Reykjavík is 5 hours behind St. Louis. Reykjavík runs on GMT+0 and St. Louis on GMT-5. 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 3 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 Reykjavík from St. Louis?

About 5,174 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 6h 35m, 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 Reykjavík and St. Louis use?

Reykjavík uses the Icelandic króna (ISK, kr); St. Louis uses the United States dollar (USD, $). 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 Reykjavík from St. Louis?

Dial the international prefix used by your carrier (often 011), then +354, 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 Reykjavík and St. Louis?

Reykjavík primarily speaks Icelandic; St. Louis speaks English. English is widely used in business contexts in major cities of both, but written contracts may need translation.

Do Reykjavík and St. Louis drive on the same side of the road?

Yes — both drive on the right. Rental cars feel identical between the two.
