What is JST in BRT?

Brasília Time is 12 hours behind

Japan Standard Time is on UTC+9:00 and Brasília Time is on UTC−3:00 right now. That gap holds all year, because both zones change their clocks together.

Scheduling between the two

There is no overlap between a nine-to-six working day in Tokyo and one in São Paulo — the gap is too wide. A call has to sit early or late for one side. Early morning in Tokyo is the usual compromise, since that is late afternoon or evening in São Paulo.

Brasília Time (BRT) is used in Rio de Janeiro and Brasília. Brazil ended daylight saving in 2019.
