◊ common questions

Quick answers. Before you book the call.

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

Port Moresby is 15 hours behind St. Louis. Port Moresby runs on GMT+10 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?

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 Port Moresby from St. Louis?

About 13,476 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 16h 21m, 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 Moresby and St. Louis use?

Port Moresby uses the Papua New Guinean kina (PGK, K); 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 Moresby from St. Louis?

Dial the international prefix used by your carrier (often 011), then +675, 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 Moresby and St. Louis?

Both Papua New Guinea and United States count English among their official languages, so business meetings often skip translation. Port Moresby also has Hiri Motu, Tok Pisin; St. Louis adds no other official tongue.

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

No. Papua New Guinea 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.
