Why people convert Santiago to EST time

Scheduling a call from Santiago to EST: a 10:00 AM start in Santiago lands at 8:00 AM in EST, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Santiago and EST are inside the 9-to-5 working day between 11:00 AM and 5:00 PM CLST time (9:00 AM–3:00 PM EST). That is roughly 6 hours of usable overlap.
Booking travel or deliveries: tracking EST local time against Santiago keeps pickup windows and arrival estimates honest across the -2h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM CLST" is unambiguous; "3 PM" across a -2h gap is not.
