Why people convert EDT to Santiago time
- Scheduling a call from EDT to Santiago: a 10:00 AM start in EDT lands at 11:00 AM in Santiago, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both EDT and Santiago are inside the 9-to-5 working day between 9:00 AM and 4:00 PM EDT time (10:00 AM–5:00 PM CLST). That is roughly 7 hours of usable overlap.
- Coordinating a EDT-based team with Santiago contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM EDT" is unambiguous; "3 PM" across a +1h gap is not.
- Block 9:00 AM–4:00 PM EDT as the recurring meeting window if you work primarily from EDT and need Santiago colleagues present.
- Santiago: Clocks fall back on Sun, Apr 4, 2027. Any meeting series spanning that date will shift by an hour in local time.
