São Paulo time explained
Brazil abolished daylight saving in 2019 after decades of use, so São Paulo now stays three hours behind UTC all year. The change was justified partly on the grounds that the energy savings had largely disappeared as air conditioning replaced lighting as the dominant summer load.
São Paulo does not observe daylight saving. Its offset from UTC is the same all year round, which makes scheduling with it noticeably simpler.
Reaching São Paulo
The São Paulo working day overlaps the US east coast almost entirely and reaches Europe until mid-afternoon, which makes it one of the better-connected cities in the southern hemisphere for scheduling.
How this page works
The time above is calculated on your own device from the IANA time zone
database that ships with your browser, using the zone
America/Sao_Paulo. Nothing is fetched from a server, and the offset
shown is whatever is currently in force rather than a
number typed into the page — so when a country changes its rules, this
page changes with it.
The difference from your own clock is worked out the same way, comparing São Paulo's current offset against your device's. If your computer's clock is wrong, so is that comparison.
