Understanding the Mumbai – Houston Time Difference
Mumbai runs on Asia/Kolkata, currently IST (UTC+5:30). Houston runs on America/Chicago, currently CDT (UTC-5:00). The gap of 10 hours and 30 minutes is simply the distance between those two offsets.
Houston observes Daylight Saving Time and Mumbai does not, so the gap between them shifts by an hour twice a year. The next shift is on Sunday, November 1, 2026, when Houston adjusts its clocks and the difference becomes 11 hours and 30 minutes. Anything scheduled across that date needs checking again.
