Kolkata is 9½ hours ahead of you today.
You never share a working hour.
There is no minute of the day when you are both at your desk. Every conversation with Kolkata costs one of you an evening or a morning.

What a usable overlap costs
To share 4 hours, you start at 03:30, or they work until 22:30. Somebody pays, and the only question is who.
Every weekday of 2026
The distance between your clocks does move, between 9½ and 10½ hours, and it buys you nothing: you share none of it whichever week it is. You change your clocks and Kolkata does not.
