São Paulo and Buenos Aires are on the same clock this week (GMT-3).

São Paulo, Brazil and Buenos Aires, Argentina are on the same clock (GMT-3), so every peak hour below is the same on both.

Buenos Aires runs on America/Argentina/Buenos_Aires (GMT-3) and São Paulo on America/Sao_Paulo (GMT-3), a difference of nothing at all this week. The peak hours themselves are measured in Buenos Aires local time, and that figure never moves. What moves is the reading on your own clock, twice a year, when either place changes for daylight saving. The two places do not always change on the same date, so for a couple of weeks each spring and autumn the difference is an hour off its usual value; that is why these pages are rebuilt every week rather than computed once.

No platform's best slot crosses midnight between Buenos Aires and São Paulo, so the day of the week is the same on both clocks. Converted times use the offsets in force this week (GMT-3). The audience-clock column never changes; the converted column is rebuilt weekly so it stays right across daylight-saving changes. The same times apply across Buenos Aires's timezone, including Córdoba.
