Why people convert ICT to Japan time
- Scheduling a call from ICT to Japan: a 10:00 AM start in ICT lands at 12:00 PM in Japan, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both ICT and Japan are inside the 9-to-5 working day between 9:00 AM and 3:00 PM ICT time (11:00 AM–5:00 PM JST). That is roughly 6 hours of usable overlap.
- Watching a live event or market open: ICT viewers need 11:00 AM in Japan to catch a 9:00 AM start there, and 10:00 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 +2h gap is not.
- Block 9:00 AM–3:00 PM ICT as the recurring meeting window if you work primarily from ICT and need Japan colleagues present.
