Time in Hanoi

—

What time is it in Hanoi right now?

Hanoi is on UTC+7 all year round, which is 7 hours ahead of UTC. So when it is 12:00 UTC, the local time in Hanoi is 19:00. The live clock at the top of this page applies that offset to the current moment and refreshes every second.

What time zone is Hanoi in?

Hanoi uses the Asia/Ho_Chi_Minh time zone, shown as GMT+7. Hanoi stays on UTC+7 all year and does not change its clocks for daylight saving time. The "compare to your time zone" section above converts any Hanoi time into your own local time instantly.

Does Hanoi observe daylight saving time?

No — Hanoi does not observe daylight saving time. Its clocks stay on UTC+7 every day of the year, so its offset from UTC never moves. The difference between Hanoi and another city therefore changes only when that other city starts or ends its own daylight saving period. If you are scheduling across the seasons, treat Hanoi as the fixed end of the pair and check the other city's dates instead.

How do I convert Hanoi time to my time zone?

Convert Hanoi time by taking its UTC+7 offset and applying the difference to your own: subtract Hanoi's offset from UTC to get the UTC time, then add your own offset. For example, 09:00 in Hanoi is 02:00 UTC. The converter above does this automatically after detecting your device's time zone, and the World Clock meeting planner lays several cities out on one colour-coded 24-hour grid.

What is the dialing code for Hanoi?

What are the best hours to call Hanoi?

Standard business hours in Hanoi — 9:00 to 17:00 local time — correspond to 02:00 to 10:00 UTC. Convert that UTC window into your own zone to find the overlap. The "best time to call" line above does this for you, using waking hours of roughly 8am–9pm on both ends so neither side is called at night.
