When the world meets at work.
Read the day in both zones.
Crossing the border. Money, language, plugs.
Money changes hands at the border: Houston uses the USD ($) and Mumbai uses the INR (₹). Conversations can stay in English, which is official in both countries. Be careful behind the wheel: Houston drives on the right, Mumbai on the left.

Quick answers. Before you book the call.
What's the time difference between Houston and Mumbai?
Houston is 10.5 hours ahead of Mumbai. Houston runs on GMT-5 and Mumbai on GMT+5:30. The gap can shift by an hour when either side enters or leaves daylight saving — the live clocks above always reflect the current offset.
When's the best time to schedule a meeting?
Standard 09:00–17:00 workdays don't intersect. Most teams compromise with one side meeting early (before 09:00) or late (after 17:00).
Does daylight saving time change the difference?
Yes, if either city observes DST. When one side shifts and the other doesn't, the gap changes by one hour. The DST badges under each clock show whether each zone is currently shifted and when the next transition lands.
