What is BRT in AKST?
Alaska Time is 5 hours behind
Brasília Time is on UTC−3:00 and Alaska Time is on UTC−8:00 right now. Alaska Time is on daylight saving, so its clocks read AKDT. The gap changes during the year — see below.

When the difference changes
Brasília Time and Alaska Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:
- Now – November 1, 2026Alaska Time is 5 hours behind
- November 1, 2026 – March 14, 2027Alaska Time is 6 hours behind
- March 14, 2027 – onwardsAlaska Time is 5 hours behind
Periods shorter than a day are not listed: both zones change at 2am in their own local time, so there are a few hours on each transition date when the gap is briefly something else.
Daylight saving
Brasília Time
Brasília Time stays on BRT all year, so its offset from UTC never moves.
Alaska Time
Clocks go back one hour at 2am local time, becoming AKST.

Scheduling between the two
Working hours overlap from 2:00 pm to 6:00 pm BRT, which is 9:00 am to 1:00 pm AKDT. Anything inside that window falls in the normal working day at both ends.
Brasília Time (BRT) is used in Rio de Janeiro and Brasília. Brazil ended daylight saving in 2019.
