Mumbai is 9 hours 30 minutes ahead of Boston right now.
Does the gap change?
The gap isn't fixed. Boston changes its clocks for daylight saving time and Mumbai doesn't, so the difference moves during the year:
- From around November 2, 2026: Mumbai ahead by 10 hours 30 minutes
- From around March 15, 2027: Mumbai ahead by 9 hours 30 minutes
Best time to meet
Normal office hours in Mumbai and Boston don't overlap. The most workable window is 7 AM to 12:30 PM in Boston, which is 4:30 PM to 10 PM in Mumbai, with one side starting early or finishing late.
For a recurring meeting, it's fairest to rotate which city takes the inconvenient slot.
