Scheduling between the two

Working hours overlap from 12:00 pm to 6:00 pm BRT, which is 9:00 am to 3:00 pm CST. Anything inside that window falls in the normal working day at both ends.

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

Central Time – Mexico (CST) is used in most of Mexico. Mexico abolished daylight saving in October 2022, so it no longer tracks US Central Time in summer.
