Time zone and UTC offset in Boise
Boise follows the America/Boise time zone, abbreviated MDT. Right now its offset from Coordinated Universal Time is UTC-6.
Daylight saving time is in effect at the moment, which means local clocks run ahead of standard time. The next change comes on Sunday, November 1, 2026 at 02:00: clocks go back 1 hour, so at 02:00 the clock goes back to 01:00 and the offset becomes UTC-7. From that day the difference from Brasília is 4 hours behind. The change after that is on Sunday, March 14, 2027 at 02:00.
Time difference between Brasília and Boise
To convert, take Brasília time and subtract 3 hours; early in the morning in Brasília it may still be the previous day in Boise. The table uses today's offsets.
Going the other way, local noon in Boise is 15:00 in Brasília, and local midnight is 03:00 in Brasília. Because Boise is behind, its calendar date is still the previous day in the first 3 hours after midnight in Brasília (until 03:00). Keep this in mind for deadlines, flights and anything scheduled around the start or end of a day.

Best time to call Boise from Brazil
Taking a 9:00 to 18:00 working day on both sides, the shared window runs from 12:00 to 18:00 in Brasília, which is 09:00 to 15:00 in Boise. That leaves 6 hours of overlap: enough for most meetings, but book early. Because Boise changes its clocks, this window shifts by one hour after the next change.
