Why people convert São Paulo to CLT time

Scheduling a call from São Paulo to CLT: a 10:00 AM start in São Paulo lands at 9:00 AM in CLT, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both São Paulo and CLT are inside the 9-to-5 working day between 10:00 AM and 5:00 PM BRT time (9:00 AM–4:00 PM CLT). That is roughly 7 hours of usable overlap.
Watching a live event or market open: São Paulo viewers need 8:00 AM in CLT to catch a 9:00 AM start there, and 1:00 AM if the event is anchored to São Paulo.

Always state the zone abbreviation, not just the hour. "3:00 PM BRT" is unambiguous; "3 PM" across a -1h gap is not.
Block 10:00 AM–5:00 PM BRT as the recurring meeting window if you work primarily from São Paulo and need CLT colleagues present.
