Why people convert ICT to Santiago time
- Scheduling a call from ICT to Santiago: a 10:00 AM start in ICT lands at 12:00 AM in Santiago, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -10h gap: ICT and Santiago have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Santiago is 11:00 PM in ICT.
- Watching a live event or market open: ICT viewers need 11:00 PM in Santiago to catch a 9:00 AM start there, and 10:00 AM 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 -10h gap is not.
- With a -10h gap there is no shared 9-to-5 window, so alternate the early start: one week ICT takes the early slot, the next week Santiago does.
