Mumbai to Oslo Meeting Time & Timezone Overlap

Scheduling between Mumbai (Asia/Kolkata) and Oslo (Europe/Oslo) is a 4.5-hour-gap problem, and almost every choice about meeting cadence flows from it. A 4.5-hour window of shared work hours is workable for short status meetings, but most actual work has to happen asynchronously. 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–Oslo 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 Oslo (Europe/Oslo).

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.

Frequently asked questions

What is the time difference between Mumbai and Oslo?
Oslo is 4.5 hours behind of Mumbai. The exact gap can shift by one hour during daylight-saving transitions in either city, so check the live overlap chart above before locking in a recurring meeting.
What is the best time to schedule a meeting between Mumbai and Oslo?
The cleanest windows usually fall in Mumbai's late afternoon, which lines up with Oslo's morning. The interactive chart highlights every overlapping work hour in green so you can pick a slot that respects both teams' core hours.
Does daylight saving affect Mumbai ↔ Oslo meetings?
Yes — Mumbai and Oslo do not always change clocks on the same date, so the gap can briefly widen or shrink by one hour each spring and autumn. Anchor your recurring invite to one city's timezone so the other side absorbs the shift.
How do I avoid scheduling meetings outside work hours in Mumbai or Oslo?
Stick to slots highlighted in green on the overlap chart — those are hours when both cities are inside a normal 9 AM to 6 PM workday. If your only overlap is one hour, rotate that slot weekly so the same team is not always the one starting early.
