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

Quick answers. Before you book the call.
What's the time difference between Nanjing and Colombo?
Nanjing is 2.5 hours behind Colombo. Nanjing runs on GMT+8 and Colombo on GMT+5:30. 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 5 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 Nanjing from Colombo?
About 4,901 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 6h 16m, not counting airport time, winds, or routing around restricted airspace.

What currency do Nanjing and Colombo use?
Nanjing uses the Chinese yuan (CNY, ¥); Colombo uses the Sri Lankan rupee (LKR, Rs රු). 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.

Dial the international prefix used by your carrier (often 00), then +86, 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 Nanjing and Colombo?
Nanjing primarily speaks Chinese; Colombo speaks Sinhala, Tamil. English is widely used in business contexts in major cities of both, but written contracts may need translation.

No. China drives on the right, Sri Lanka 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.
