Three numbers. The ones that decide the meeting.
When the world meets at work.
Read the day in both zones.
Crossing the border. Money, language, plugs.
Money changes hands at the border: Luanda uses the AOA (Kz) and Houston uses the USD ($). Language shifts too — Portuguese in Luanda, English in Houston. Cars drive on the right in both, so rentals feel familiar.

Quick answers. Before you book the call.
What's the time difference between Luanda and Houston?
Luanda is 6 hours behind Houston. Luanda runs on GMT+1 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's the best time to schedule a meeting?
There are 2 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 Luanda from Houston?
About 12,290 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 14h 58m, 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 Luanda and Houston use?
Luanda uses the Angolan kwanza (AOA, Kz); 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 Luanda from Houston?
Dial the international prefix used by your carrier (often 011), then +244, 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 Luanda and Houston?
Luanda primarily speaks Portuguese; Houston speaks English. English is widely used in business contexts in major cities of both, but written contracts may need translation.
Do Luanda and Houston drive on the same side of the road?
Yes — both drive on the right. Rental cars feel identical between the two.
