Time Difference: Tokyo to Ho Chi Minh City

Summary

Tokyo (JST, UTC+9) is always 2 hours ahead of Ho Chi Minh City (ICT, UTC+7) — neither city observes Daylight Saving Time, so the gap never changes.

How it works

1. Your browser reads the current moment from your device clock.
2. It converts that moment to Asia/Tokyo time (JST, UTC+9) using the IANA timezone database.
3. The same moment is converted to Asia/Ho_Chi_Minh time (ICT, UTC+7).
4. The UTC offsets are compared: Tokyo is UTC+9, Ho Chi Minh City is UTC+7, giving a fixed +2 hour gap.
5. All values — Tokyo time, Ho Chi Minh City time, and the offset — refresh every second.
6. Because neither country uses Daylight Saving Time, the 2-hour gap never changes.
