Why people convert ICT to NZDT time
- Scheduling a call from ICT to NZDT: a 10:00 AM start in ICT lands at 4:00 PM in NZDT, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both ICT and NZDT are inside the 9-to-5 working day between 9:00 AM and 11:00 AM ICT time (3:00 PM–5:00 PM NZDT). That is roughly 2 hours of usable overlap.
- Watching a live event or market open: ICT viewers need 3:00 PM in NZDT to catch a 9:00 AM start there, and 6:00 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 +6h gap is not.
- Block 9:00 AM–11:00 AM ICT as the recurring meeting window if you work primarily from ICT and need NZDT colleagues present.
