How many hours ahead is São Paulo of Seoul?

Why do the times differ between São Paulo and Seoul?

São Paulo, Brazil (GMT-3) is 12 hours behind Seoul, South Korea (GMT+9).

How is this conversion worked out?

Seoul runs on Asia/Seoul (GMT+9) and São Paulo on America/Sao_Paulo (GMT-3), a difference of 12 hours this week. The peak hours themselves are measured in Seoul 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.

Does any platform peak on a different day in São Paulo?

Facebook, X and YouTube peak on a different calendar day in São Paulo than in Seoul, so scheduling by day name alone will miss them. Converted times use the offsets in force this week (GMT-3 and GMT+9). 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 Seoul's timezone, including Busan.
