Time Difference: Thailand to Vietnam

Live conversion between Bangkok (Asia/Bangkok) and Hanoi (Asia/Bangkok) with automatic Daylight Saving Time handling.

About This Time Conversion

This page converts the local time between Bangkok, Thailand (timezone Asia/Bangkok, currently ++7, GMT+7) and Hanoi, Vietnam (timezone Asia/Bangkok, currently ++7, GMT+7). TZSync uses the IANA timezone database so conversions always account for Daylight Saving Time, half-hour offsets such as India (UTC+5:30), and quarter-hour offsets such as Nepal (UTC+5:45).

When it is daytime in Bangkok, the clock in Hanoi reads the same day and a nearby hour. Drag the time slider on this page to find an overlap where both cities are inside typical working hours (9 AM – 5 PM local time) — that overlap is your best window for meetings, calls, and collaboration between Bangkok and Hanoi.
