AST to BRT time conversion

The difference between AST and BRT is fixed: BRT is 1 hour ahead of AST. For example, 9:00 AM (09:00) AST is 10:00 BRT, and 6:00 PM (18:00) AST is 19:00 BRT. The chart above lists the conversion for every hour of the day.

These conversions use each zone's standard UTC offset — UTC−04:00 for AST (Atlantic Standard Time) and UTC−03:00 for BRT (Brasilia Time) — so the result is exact and does not shift with Daylight Saving Time. To convert a real calendar date between cities with automatic DST handling, use the full time zone converter.
