Convert BRT (Brasília Time) to PST (Pacific Standard Time)

Best time to schedule a meeting

Standard 9–5 working hours overlap for 3 hours: 2:00 PM–5:00 PM BRT (9:00 AM–12:00 PM PST). Schedule meetings inside that window.

About BRT

Brasília Time (BRT) is UTC−3. It is used in São Paulo, Rio de Janeiro and most of populated Brazil.

Brasília Time is UTC−3, covering São Paulo, Rio de Janeiro and Brasília. Brazil abolished daylight saving in 2019, so the offset is now fixed year-round — but a great deal of older software, and a lot of published advice, still assumes the southern-hemisphere shift that used to run from October to February. If a Brazilian meeting time was correct last year and is an hour out now, an out-of-date time zone database is the likely cause.

About PST

Pacific Standard Time (PST) is UTC−8. It is used in Los Angeles, San Francisco, Seattle and Vancouver in winter.

Pacific Standard Time is UTC−8, used by Los Angeles, San Francisco, Seattle and Vancouver from November to March. As with EST, the abbreviation is written all year in practice — a great deal of software, and most conference invitations from the US west coast, say PST when the sender means PDT. If a time from a US source looks an hour off between March and November, this is almost always why.

Does this gap change with the seasons?

This gap is seasonal. The abbreviations themselves are fixed offsets, but the region on PST switches to PDT (UTC−7) from March to November. So the 5-hour figure on this page is correct for the part of the year when both places are actually on these abbreviations, and changes by an hour outside it.

BRT does not shift, so the whole change comes from one side. A recurring meeting fixed in BRT will appear to move by an hour for everyone on the other side, twice a year, without anyone changing anything.

This is the reason scheduling systems store an IANA zone such as Region/City rather than an offset or an abbreviation: the zone knows its own rules and the offset does not.
