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: Colombo uses the LKR (Rs රු) and Chengdu uses the CNY (¥). Language shifts too — Sinhala in Colombo, Chinese in Chengdu. Be careful behind the wheel: Colombo drives on the left, Chengdu on the right.

Quick answers. Before you book the call.
What's the time difference between Colombo and Chengdu?
Colombo is 2.5 hours ahead of Chengdu. Colombo runs on GMT+5:30 and Chengdu on GMT+8. 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 6 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 Colombo from Chengdu?
About 3,643 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 4h 47m, 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 Colombo and Chengdu use?
Colombo uses the Sri Lankan rupee (LKR, Rs රු); Chengdu uses the Chinese yuan (CNY, ¥). 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 Colombo from Chengdu?
Dial the international prefix used by your carrier (often 00), then +94, 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 Colombo and Chengdu?
Colombo primarily speaks Sinhala, Tamil; Chengdu speaks Chinese. English is widely used in business contexts in major cities of both, but written contracts may need translation.
Do Colombo and Chengdu drive on the same side of the road?
No. Sri Lanka drives on the left, China 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.
