Time zone and UTC offset in Buenos Aires
Buenos Aires follows the America/Argentina/Buenos_Aires time zone (this zone has no widely used letter abbreviation). Right now its offset from Coordinated Universal Time is UTC-3.
Buenos Aires does not observe daylight saving time and no clock change is scheduled for the next year. Its offset stays at UTC-3 all year round. Brazil abolished daylight saving time in 2019, so the gap between the two stays fixed at zero. 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 Buenos Aires.
