Why people convert Vietnam to Shanghai time
- Scheduling a call from Vietnam to Shanghai: a 10:00 AM start in Vietnam lands at 11:00 AM in Shanghai, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Vietnam and Shanghai are inside the 9-to-5 working day between 9:00 AM and 4:00 PM ICT time (10:00 AM–5:00 PM CST). That is roughly 7 hours of usable overlap.
- Coordinating a Vietnam-based team with Shanghai contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- 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 Shanghai colleagues present.
