Why people convert Santiago to Auckland time

Scheduling a call from Santiago to Auckland: a 10:00 AM start in Santiago lands at 2:00 AM in Auckland the next day, so you can confirm the slot without doing the arithmetic yourself.
Handling a +16h gap: Santiago and Auckland 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 Auckland is 1:00 AM in Santiago.
Keeping family and friends in sync: knowing that 8:00 PM in Santiago is 12:00 PM in Auckland makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM CLST" is unambiguous; "3 PM" across a +16h gap is not.
With a +16h gap there is no shared 9-to-5 window, so alternate the early start: one week Santiago takes the early slot, the next week Auckland does.
Santiago: Clocks fall back on Sun, Apr 4, 2027. Re-check this page after that date because the offset changes and so does the +16h gap.
Auckland: Clocks fall back on Sat, Apr 3, 2027. Any meeting series spanning that date will shift by an hour in local time.
