People in the state of Tocantins will set their clocks 1 hour forward – from 00:00 to 01:00 local time – along with people in southern, southeastern, and midwestern Brazilian states. This is the first time in 9 years that Tocantins will be observing DST.

DST dates worldwide – second half of 2012

Bahia not to observe DST

Bahia reinstated DST in 2011 after abolishing it in 2003. But fearing violence, the governor of Bahia withdrew his state’s name from the list and people in Bahia will not be moving their clocks forward in 2012.

States with DST


Daylight Saving Time is controversial in Brazil. Critics of DST argue that not only do changes in the clock negatively affect the human body, but also have an adverse impact on businesses.

Supporters of DST, on the other hand, suggest that observing the time change will reduce energy costs. It is estimated that DST will save the Brazilian government 280 million Reals (137 million USD) in 2012-2013, despite the non-participation of Bahia.

DST ends in Brazil in February 2013

DST in Brazil will end at midnight on Sunday, February 17, 2013 when people in the states observing DST will move their clocks backward by 1 hour.

Update: Some news sources are reporting that following opposition by businesses, the governor of Tocantins is considering withdrawing the state’s name from the list. The change has not been confirmed yet. timeanddate.com is following this news story closely, and will update the DST information about Brazil as soon as a decision is announced.
