◊ common questions

Quick answers. Before you book the call.

What's the time difference between San Francisco and Asunción?

San Francisco is 4 hours ahead of Asunción. San Francisco runs on GMT-7 and Asunción 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?

There are 4 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 San Francisco from Asunción?

About 9,737 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 11h 57m, not counting airport time, winds, or routing around restricted airspace.

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 Francisco and Asunción use?

San Francisco uses the United States dollar (USD, $); Asunción uses the Paraguayan guaraní (PYG, ₲). 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.

What language is spoken in San Francisco and Asunción?

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