Time in Rio de Janeiro, Brazil

Time zone: -03 (UTC/GMT -03:00) — America/Sao_Paulo

Rio de Janeiro keeps -03 (3 hours behind UTC, UTC-03:00). Its database zone is America/Sao_Paulo — worth knowing if you are scheduling anything that has to survive a daylight saving change.

Clocks in Rio de Janeiro stay put. With no summer-time switch, the UTC-03:00 offset is fixed and the differences shown below only shift when the other end changes.

Rio de Janeiro is one of 235 Brazil cities here, spread over 15 time zones; do not assume the rest of the country reads the same clock.

How Rio de Janeiro lines up against other major centres at this moment — the numbers move when either side changes its clocks.

Assuming a 09:00–17:00 day at both ends, these windows (in Rio de Janeiro local time) fall inside working hours for both cities.

No shared working window exists with Mumbai, Shanghai, Tokyo or Sydney, so those calls have to sit outside somebody's normal hours.

These Brazil cities also use America/Sao_Paulo, so their clocks read identically to Rio de Janeiro at every moment of the year.
