Why people convert São Paulo to MDT time

Scheduling a call from São Paulo to MDT: a 10:00 AM start in São Paulo lands at 7:00 AM in MDT, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both São Paulo and MDT are inside the 9-to-5 working day between 12:00 PM and 5:00 PM BRT time (9:00 AM–2:00 PM MDT). That is roughly 5 hours of usable overlap.
