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 If a Brazilian meeting time was correct last year and is an hour out now, an out-of-date time zone database is the likely cause.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 WAT

West Africa Time (WAT) is UTC+1. It is used in Nigeria, Cameroon, Angola and much of central and western Africa.

West Africa Time is UTC+1 all year, with no daylight saving anywhere that uses it. It covers Lagos, Kinshasa and Luanda — a very large population on a single fixed offset. It matches Central European Time in winter and falls an hour behind it in summer, which means a standing Europe–Nigeria meeting moves twice a year at the European end and never at the African one.

Does this gap change with the seasons?

Neither BRT nor WAT shifts with the seasons, so this 4-hour difference holds all year. That is unusual enough to be worth relying on: most cross-continental gaps move twice a year.

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.

Frequently asked questions

What time is 9:00 AM BRT in WAT?

Is WAT ahead of BRT?

WAT is 4 hours ahead of BRT.

Which time zone does this use?

BRT is UTC−3 and WAT is UTC+1. Both abbreviations denote a single fixed offset, so this conversion never shifts with daylight saving — what changes is which abbreviation a place is using at the time.
