Best Meeting Time: Singapore to Hanoi
🕐 Live Timezone Overlap: Singapore & Hanoi
Meetings between Singapore and Hanoi hinge on a 8-hour window each working day. Singapore sits 1 hour behind Hanoi at the time of writing, which puts the comfortable overlap at 10:00 AM to 6:00 PM Singapore time. Teams that work across these two cities tend to anchor their week-on-week sync into that block and push everything else to written updates. The widget below shows the exact mapping in both directions, including the small DST seasonal shift when one or both cities change clocks.
Time Difference: Singapore and Hanoi
Hanoi is currently 1 hour behind Singapore. The live offsets are Singapore UTC+8 and Hanoi UTC+7. Singapore does not observe daylight saving and Hanoi does not, so the offset shifts twice a year if both sides aren't already aligned.
Singapore does not observe DST, and Hanoi does not. When either side switches, the offset shifts by an hour. The US and Europe also change clocks on different weekends, so for one week in spring and one in autumn the usual offset between US and European cities is off by an hour. Always confirm with the live tool above when you're scheduling a recurring meeting that spans a DST changeover.
Best Times to Meet
Inside the 8-hour overlap, the best slots depend on local culture. Singapore tends to favour mid-morning meetings; Hanoi works 9am–6pm as a default. Aim for the middle of the window where neither side is just starting or wrapping up. Avoid Friday afternoons if the other party has a strong end-of-week culture, and skip lunchtime in whichever city is in the 12–2pm block.

Tips for Scheduling Across Singapore and Hanoi
- Aim for around 2:00 PM Singapore time: the middle of the overlap leaves room for both sides if the call runs long.
- Neither city observes DST, so the offset between Singapore and Hanoi stays constant year-round.
- Check Vietnam's public holiday calendar in advance: a few national holidays shift entire working weeks.
- Most multinational APAC HQs are based in Singapore; 9am-6pm is the firm norm.
- The gap is small enough that most teams keep one shared calendar in Singapore time and convert mentally.
Public Holidays and Working Weeks
Singapore runs a Monday–Friday working week with Chinese New Year (January or February (movable)) and National Day (08-09) among the key closures. Vietnam's major holidays include a standard public holiday set. Cross-check both calendars when scheduling recurring meetings: a 30-minute call in one city's holiday week typically gets a much lower attendance rate than the same slot a week later.
