Why people convert Vietnam to SGT time

Scheduling a call from Vietnam to SGT: a 10:00 AM start in Vietnam lands at 11:00 AM in SGT, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Vietnam and SGT are inside the 9-to-5 working day between 9:00 AM and 4:00 PM ICT time (10:00 AM–5:00 PM SGT). That is roughly 7 hours of usable overlap.
Booking travel or deliveries: tracking SGT local time against Vietnam keeps pickup windows and arrival estimates honest across the +1h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM ICT" is unambiguous; "3 PM" across a +1h gap is not.
Block 9:00 AM–4:00 PM ICT as the recurring meeting window if you work primarily from Vietnam and need SGT colleagues present.
