Mumbai to Warsaw Meeting Time & Timezone Overlap

Scheduling between Mumbai (Asia/Kolkata) and Warsaw (Europe/Warsaw) is a 4.5-hour-gap problem, and almost every choice about meeting cadence flows from it. With only 4.5 hours of overlap during business time, recurring meetings need to be precise — there's no slack for spillover. The page below shows the live hour-by-hour comparison, the cleanest meeting windows, and the DST shifts that change the overlap on specific dates in 2026.

Mumbai–Warsaw working-hour overlap window

The shared working window is 1.5:00 PM – 6:00 PM in Mumbai (Asia/Kolkata), which lines up with 9:00 AM – 1.5:00 PM in Warsaw (Europe/Warsaw).

For recurring meetings the most attendance-friendly start time is 1.5:00 PM Mumbai time. Booking inside the shared window means neither side has to take the call before breakfast or after dinner.

Daylight saving advisory

Warsaw observes daylight saving time; Mumbai does not. The effective time difference between the two cities therefore shifts by one hour twice a year. In 2026, the change dates that matter for this pair are:

  • Spring shift in Warsaw — last Sunday of March (Europe) or second Sunday of March (North America)
  • Autumn shift in Warsaw — last Sunday of October (Europe) or first Sunday of November (North America)

If you book a recurring meeting that already sits at the edge of the overlap window, expect it to drop out for roughly four weeks each spring and autumn when the windows realign.

Business-hours context for Mumbai and Warsaw

Standard business hours in Mumbai run 10:00–19:00 local time, with the weekend on Saturday and Sunday. In Warsaw, standard hours are 8:00–16:00 with the weekend on Saturday and Sunday.

Both cities share Saturday–Sunday as the weekend, so the only constraint is the time-of-day overlap.

Meeting scheduling strategies for Mumbai–Warsaw
