CET to BRT — Brasília Time is 4 hours behind
Brasília Time (BRT) is 4 hours behind of Central European Time (CET) while both are on standard time. Once daylight saving starts the gap becomes 5 hours behind, so any recurring meeting between these two regions moves by an hour twice a year.
Standard time
4 hours behindApplies while neither zone is on daylight saving — broadly November to March in the northern hemisphere.
Daylight saving
5 hours behindApplies while the clocks are forward. This pair does not keep a constant gap, so check the date.

Questions people ask
4 hours behind during standard time, and 5 hours behind while daylight saving is running.
No. One zone shifts and the other does not, or they shift on different dates, which is why the difference is not a single fixed number.
There are a few hours of shared working time. Booking towards the start of the later zone's day usually suits everybody.
Booking something recurring?
A fixed clock time drifts when either side changes its clocks. Our guides explain how to stop that happening.
