◊ travel essentials

Crossing the border. Money, language, plugs.

Money changes hands at the border: Vientiane uses the LAK (₭) and San José uses the CRC (₡). Language shifts too — Lao in Vientiane, Spanish in San José. 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 Vientiane and San José?

Vientiane is 13 hours behind San José. Vientiane runs on GMT+7 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?

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 Vientiane from San José?

About 16,826 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 20h 18m, 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 Vientiane and San José use?

Vientiane uses the Lao kip (LAK, ₭); 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 Vientiane from San José?

Dial the international prefix used by your carrier (often 00), then +856, 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 Vientiane and San José?

Vientiane primarily speaks Lao; San José speaks Spanish. English is widely used in business contexts in major cities of both, but written contracts may need translation.

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

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