◊ travel essentials

Crossing the border. Money, language, plugs.

Money changes hands at the border: Khartoum uses the SDG (ج.س) and Nukuʻalofa uses the TOP (T$). Conversations can stay in English, which is official in both countries. Be careful behind the wheel: Khartoum drives on the right, Nukuʻalofa on the left.

◊ common questions

Quick answers. Before you book the call.

What's the time difference between Khartoum and Nukuʻalofa?

Khartoum is 11 hours ahead of Nukuʻalofa. Khartoum runs on GMT+2 and Nukuʻalofa on GMT+13. 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 Khartoum from Nukuʻalofa?

About 17,022 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 20h 32m, 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 Khartoum and Nukuʻalofa use?

Khartoum uses the Sudanese pound (SDG, ج.س); Nukuʻalofa uses the Tongan paʻanga (TOP, T$). 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 Khartoum from Nukuʻalofa?

Dial the international prefix used by your carrier (often 00), then +249, 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 Khartoum and Nukuʻalofa?

Both Sudan and Tonga count English among their official languages, so business meetings often skip translation. Khartoum also has Arabic; Nukuʻalofa adds Tongan.

Do Khartoum and Nukuʻalofa drive on the same side of the road?

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