◊ common questions

Quick answers. Before you book the call.

What's the time difference between Buenos Aires and San José?

Buenos Aires is 3 hours behind San José. Buenos Aires runs on GMT-3 and San José on GMT-6. 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 5 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 Buenos Aires from San José?

About 5,644 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 7h 8m, 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 Buenos Aires and San José use?

Buenos Aires uses the Argentine peso (ARS, $); San José uses the Costa Rican colón (CRC, ₡). 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 Buenos Aires from San José?

Dial the international prefix used by your carrier (often 00), then +54, 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 Buenos Aires and San José?

Both Argentina and Costa Rica count Spanish among their official languages, so business meetings often skip translation. Buenos Aires also has Guaraní; San José adds no other official tongue.

Do Buenos Aires and San José drive on the same side of the road?

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