Vietnam and India Time Zones Explained
Vietnam uses Indochina Time, which is 7 hours ahead of Coordinated Universal Time (UTC+7). Thailand, Cambodia and Laos use the same offset. India uses India Standard Time (IST), which is UTC+5:30, across the whole country.
The gap is the difference between the two: 7 hours minus 5 hours 30 minutes equals 1 hour 30 minutes. Vietnam does not use daylight saving time, and neither does India, so the gap never changes.
How to Convert ICT to IST
- Vietnam time to India time: subtract 1 hour 30 minutes.
- India time to Vietnam time: add 1 hour 30 minutes.
An easy way to do it in your head is to take away 2 hours, then add back 30 minutes. For example, 7:00 PM in Hanoi becomes 5:00 PM, then 5:30 PM in India.

Planning a Trip to Vietnam
Non-stop flights to Vietnam run from several Indian cities, and Delhi to Hanoi or Ho Chi Minh City usually takes roughly 4.5 to 6 hours. Routes and schedules change, so check with the airline. The gap is only 1 hour 30 minutes, so jet lag is mild. Get daylight on the morning after you land and sleep at a normal Vietnam bedtime.
Indian passport holders usually need to apply for a visa or e-visa before travelling, and the rules can change, so check the official Vietnam immigration website before you book. For trip costs and timing, read our guides on whether Vietnam is still cheap in 2026, the best time to visit Vietnam on a budget and Vietnam versus Thailand for budget travel.

Common Mistakes to Avoid
- Adding instead of subtracting. Vietnam is ahead of India, so subtract 1 hour 30 minutes from Vietnam time to get India time.
- Mixing up ICT. It also stands for information technology. Write Vietnam time or UTC+7 to be clear.
- Missing the date change. After 10:30 PM in India, it is already the next day in Vietnam.
- Forgetting Tet. Calls and deliveries around the Lunar New Year may go unanswered.
- Looking for daylight saving. It is not used, so the gap does not change.
