Why people convert ICT to Hong Kong time
- Scheduling a call from ICT to Hong Kong: a 10:00 AM start in ICT lands at 11:00 AM in Hong Kong, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both ICT and Hong Kong are inside the 9-to-5 working day between 9:00 AM and 4:00 PM ICT time (10:00 AM–5:00 PM HKT). That is roughly 7 hours of usable overlap.
- Keeping family and friends in sync: knowing that 8:00 PM in ICT is 9:00 PM in Hong Kong makes it easy to avoid calling at 3 AM.

- Block 9:00 AM–4:00 PM ICT as the recurring meeting window if you work primarily from ICT and need Hong Kong colleagues present.
