9am in London is 1:30pm in Mumbai

When it’s 9am in London, it’s 2pm in Mumbai. Mumbai is 5 hours 30 minutes ahead London. London observes daylight saving time but Mumbai does not, so the gap shifts by one hour during clock changes. The best time to schedule calls between the two cities is 9am to 12pm (noon) London time (which is 2pm to 5pm in Mumbai). Deal teams connecting London and Mumbai tend to schedule calls mid-morning in the earlier city, which lands in early afternoon for the other side. In practice, teams in London tend to take early-morning calls to reach Mumbai during standard afternoon hours, while Mumbai counterparts can schedule near end of day. Having a standing calendar slot for cross-city calls reduces back-and-forth over scheduling and keeps projects moving efficiently.
