About BRT and PST
BRT (Brasília Time) covers Brazil and is anchored to the IANA zone America/Sao_Paulo. It does not observe daylight saving time — the offset stays fixed all year.
PST (Pacific Time (US)) covers USA and Canada via America/Los_Angeles. It observes daylight saving time, so the gap between these two zones shifts twice a year.
Because at least one of these zones uses DST, the time difference between BRT and PST is not constant — it shifts by an hour during the spring and autumn DST transitions. The hour grid below recomputes the difference for any specific date you click, using the IANA rules baked into your browser.
