Daylight Saving Time (DST)

The clocks change twice a year moving from winter (standard) time to summer time and back. Find out when, and how Brazilian time relates to the rest of the world...

In 2008, Brazil standardized Daylight Saving Time (DST) and introduced a DST schedule. Most Southern States in Brazil observe DST. These include: Rio Grande do Sul, Santa Catarina, Paraná, São Paulo, Rio de Janeiro, Espirito Santo, Minas Gerais, Goias, Matto Grosso, Matto Grosso do Sul, Distrito Federal. Equatorial Brazil does not observe Daylight Saving Time (DST).

Due to its geographic size, there are four time zones in Brazil.

  • Clocks go back by one hour at midnight on the third Sunday of February
  • They go forward at midnight on the third Sunday of October

When dealing with other countries, it can be helpful to know the different varieties of DST (for those countries that use the system) and how they map on to each other. Most countries adjust their clocks at some time between midnight and 03:00.

Note: Many countries and territories change days of transitions to DST from year to year and some do not employ it every year.
