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: Muscat uses the OMR (ر.ع.) and Chennai uses the INR (₹). Language shifts too — Arabic in Muscat, English in Chennai. Be careful behind the wheel: Muscat drives on the right, Chennai on the left.

Quick answers. Before you book the call.
What's the time difference between Muscat and Chennai?
Muscat is 1.5 hours ahead of Chennai. Muscat runs on GMT+4 and Chennai 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 7 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 Muscat from Chennai?
About 2,581 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 3h 32m, not counting airport time, winds, or routing around restricted airspace.

What currency do Muscat and Chennai use?
Muscat uses the Omani rial (OMR, ر.ع.); Chennai uses the Indian rupee (INR, ₹). 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.

What language is spoken in Muscat and Chennai?
Muscat primarily speaks Arabic; Chennai speaks English, Hindi, Tamil. English is widely used in business contexts in major cities of both, but written contracts may need translation.
