◊ common questions

Quick answers. Before you book the call.

What's the time difference between Christchurch and Kolkata?

Christchurch is 6.5 hours behind Kolkata. Christchurch runs on GMT+12 and Kolkata 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 1 hour 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 Christchurch from Kolkata?

About 11,275 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 13h 46m, not counting airport time, winds, or routing around restricted airspace.
