Kolkata sits at 22.5726°N, 88.3639°E, while Mumbai is located at 19.0760°N, 72.8777°E. The initial compass bearing from Kolkata to Mumbai is 259° (W), so a great-circle flight path leaves Kolkata heading roughly W. Because the Earth is curved, the actual heading shifts gradually along the route — pilots and navigation systems update it continuously instead of holding a single fixed compass bearing.
The latitude difference is 3.50° and the longitude difference is 15.49°. Each degree of latitude represents about 111 km, which is one reason cross-latitude routes feel longer even when the map looks similar to east–west journeys.
The geographic midpoint between Kolkata and Mumbai is approximately 20.9993°N, 80.5304°E. This is the great-circle halfway position — the spot where you would be exactly 828 km from each city. On long-haul flights this point usually falls over open ocean or remote terrain, which is why in-flight maps often look "empty" mid-route.
Mumbai is roughly 1 hour behind Kolkata. When it is 09:00 in Kolkata, it is approximately 08:00 in Mumbai. Daylight saving time can shift the offset by an hour during certain months, so confirm the exact difference for your specific travel dates.
