Why people convert Santiago to CDT time

Scheduling a call from Santiago to CDT: a 10:00 AM start in Santiago lands at 8:00 AM in CDT, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Santiago and CDT are inside the 9-to-5 working day between 11:00 AM and 5:00 PM CLST time (9:00 AM–3:00 PM CDT). That is roughly 6 hours of usable overlap.
Coordinating a Santiago-based team with CDT 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 CLST" is unambiguous; "3 PM" across a -2h gap is not.
Block 11:00 AM–5:00 PM CLST as the recurring meeting window if you work primarily from Santiago and need CDT colleagues present.
Santiago: Clocks fall back on Sun, Apr 4, 2027. Re-check this page after that date because the offset changes and so does the -2h gap.
