Hanoi does not change its clocks
A fixed offset, all year round
Hanoi stays on Indochina Time at UTC+07:00 every day of the year. There is no spring-forward or fall-back here, which puts it with the majority: most of the world's time zones do not observe daylight saving.
That sounds like it makes scheduling simpler, and locally it does — but it introduces a different trap for anyone working with Hanoi from a country that does change clocks. The offset between you and Hanoi is not constant: it changes when your clocks move, even though nothing changed here. A recurring call that has run at the same local time for months will shift by an hour, from your side, without anyone editing the invite.
When the gap to Hanoi changes
Dates in the next year where the difference shifts, by counterpart city
The difference between two cities is not a constant. It changes whenever either side moves its clocks — and because regions switch on different dates, there are short windows each year when the usual gap is wrong. These are the dates that matter for Hanoi:

- From 25 October 2026: Hanoi is 7 hours ahead of London
- From 28 March 2027: Hanoi is 6 hours ahead of London

Hanoi's clock is unusually well matched to the sun: local noon falls within 3 minutes of the moment the sun is actually overhead. Most cities sit further out, because time zones follow borders rather than longitude.
