◊ common questions

Quick answers. Before you book the call.

What's the time difference between Port of Spain and St. Louis?

Port of Spain is 1 hour behind St. Louis. Port of Spain runs on GMT-4 and St. Louis on GMT-5. 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 7 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 Port of Spain from St. Louis?

About 4,216 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 5h 28m, 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 Port of Spain and St. Louis use?

Port of Spain uses the Trinidad and Tobago dollar (TTD, $); St. Louis uses the United States dollar (USD, $). 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 Port of Spain from St. Louis?

Dial the international prefix used by your carrier (often 011), then +1868, 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 Port of Spain and St. Louis?

Both Trinidad and Tobago and United States count English among their official languages, so business meetings often skip translation. Port of Spain also has no other official tongue; St. Louis adds no other official tongue.

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

No. Trinidad and Tobago drives on the left, United States on the right. If you're renting, expect a learning curve on the first day — especially at roundabouts and when judging the centre of the lane.
