Time zone and UTC offset in Monterrey
Monterrey follows the America/Monterrey time zone, abbreviated CST. Right now its offset from Coordinated Universal Time is UTC-6.
Monterrey does not observe daylight saving time and no clock change is scheduled for the next year. Its offset stays at UTC-6 all year round. Brazil abolished daylight saving time in 2019, so the gap between the two stays fixed at 3 hours. That makes scheduling predictable: a meeting booked for any date of the year at a given Brasília time always lands at the same local time in Monterrey.
Time difference between Brasília and Monterrey
To convert, take Brasília time and subtract 3 hours; early in the morning in Brasília it may still be the previous day in Monterrey. The table uses today's offsets.
Going the other way, local noon in Monterrey is 15:00 in Brasília, and local midnight is 03:00 in Brasília. Because Monterrey is behind, its calendar date is still the previous day in the first 3 hours after midnight in Brasília (until 03:00). Keep this in mind for deadlines, flights and anything scheduled around the start or end of a day.
