Why people convert ICT to AWST time
- Scheduling a call from ICT to AWST: a 10:00 AM start in ICT lands at 11:00 AM in AWST, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both ICT and AWST are inside the 9-to-5 working day between 9:00 AM and 4:00 PM ICT time (10:00 AM–5:00 PM AWST). That is roughly 7 hours of usable overlap.
- Watching a live event or market open: ICT viewers need 10:00 AM in AWST to catch a 9:00 AM start there, and 11:00 PM if the event is anchored to ICT.
- 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 ICT and need AWST colleagues present.
