◊ travel essentials

Crossing the border. Money, language, plugs.

Money changes hands at the border: St. Louis uses the USD ($) and Antananarivo uses the MGA (Ar). Language shifts too — English in St. Louis, French in Antananarivo. 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 St. Louis and Antananarivo?

St. Louis is 8 hours ahead of Antananarivo. St. Louis runs on GMT-5 and Antananarivo on GMT+3. 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 St. Louis from Antananarivo?

About 15,399 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 18h 37m, 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 St. Louis and Antananarivo use?

St. Louis uses the United States dollar (USD, $); Antananarivo uses the Malagasy ariary (MGA, Ar). 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 St. Louis from Antananarivo?

Dial the international prefix used by your carrier (often 00), then +1, 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 St. Louis and Antananarivo?

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

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

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