Brasília Time
America/Sao_Paulo is currently on UTC-03:00 (UTC-03:00). That is not BRT — this page is named for the abbreviation people search for, and tells you the truth about which one is actually in force.

Brasília Time is UTC-3. Brazil abolished daylight saving in 2019, so the offset no longer moves — a rule change many stale converters still get wrong.
