Why people convert AEST to São Paulo time

Scheduling a call from AEST to São Paulo: a 10:00 AM start in AEST lands at 9:00 PM in São Paulo the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -13h gap: AEST and São Paulo 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 São Paulo is 8:00 PM in AEST.
Keeping family and friends in sync: knowing that 8:00 PM in AEST is 7:00 AM in São Paulo makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM AEST" is unambiguous; "3 PM" across a -13h gap is not.
With a -13h gap there is no shared 9-to-5 window, so alternate the early start: one week AEST takes the early slot, the next week São Paulo does.
