◊ travel essentials

Crossing the border. Money, language, plugs.

Money changes hands at the border: San José uses the CRC (₡) and Dar es Salaam uses the TZS (Sh). Language shifts too — Spanish in San José, English in Dar es Salaam. Be careful behind the wheel: San José drives on the right, Dar es Salaam on the left.

◊ common questions

Quick answers. Before you book the call.

What's the time difference between San José and Dar es Salaam?

San José is 9 hours ahead of Dar es Salaam. San José runs on GMT-6 and Dar es Salaam 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 San José from Dar es Salaam?

About 13,774 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 16h 42m, 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 San José and Dar es Salaam use?

San José uses the Costa Rican colón (CRC, ₡); Dar es Salaam uses the Tanzanian shilling (TZS, Sh). 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 San José from Dar es Salaam?

Dial the international prefix used by your carrier (often 00), then +506, 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 San José and Dar es Salaam?

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

Do San José and Dar es Salaam drive on the same side of the road?

No. Costa Rica drives on the right, Tanzania 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.
