Why people convert Dubai to São Paulo time

Scheduling a call from Dubai to São Paulo: a 10:00 AM start in Dubai lands at 3:00 AM in São Paulo, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Dubai and São Paulo are inside the 9-to-5 working day between 4:00 PM and 5:00 PM GST time (9:00 AM–10:00 AM BRT). That is roughly 1 hours of usable overlap.
Watching a live event or market open: Dubai viewers need 2:00 AM in São Paulo to catch a 9:00 AM start there, and 7:00 AM if the event is anchored to Dubai.

Always state the zone abbreviation, not just the hour. "3:00 PM GST" is unambiguous; "3 PM" across a -7h gap is not.
Block 4:00 PM–5:00 PM GST as the recurring meeting window if you work primarily from Dubai and need São Paulo colleagues present.
