◊ common questions

Quick answers. Before you book the call.

What's the time difference between Adelaide and Houston?

Adelaide is 15.5 hours behind Houston. Adelaide runs on GMT+10:30 and Houston 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 it's 10 am in Adelaide, what time is it in Houston?

10:00 am in Adelaide is 6:30 pm in Houston the previous day — evening there. The same shift applies to any hour; the quick-conversion cards and the 24-hour table above cover the full day.

When it's 3 pm in Adelaide, what time is it in Houston?

3:00 pm in Adelaide is 11:30 pm in Houston the previous day — night there. The same shift applies to any hour; the quick-conversion cards and the 24-hour table above cover the full day.

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 Adelaide from Houston?

About 14,973 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 18h 7m, 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 Adelaide and Houston use?

Adelaide uses the Australian dollar (AUD, $); Houston 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 Adelaide from Houston?

Dial the international prefix used by your carrier (often 011), then +61, 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 Adelaide and Houston?

Both Australia and United States count English among their official languages, so business meetings often skip translation. Adelaide also has no other official tongue; Houston adds no other official tongue.

Do Adelaide and Houston drive on the same side of the road?

No. Australia 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.
