CAMARB publishes, on this page, the 2026 Calendar in PDF, with the dates scheduled in Administrative Resolution No. 35/2025. The calendar details the holidays and optional holidays that impact the deadlines in arbitration, dispute board and mediation procedures.

Business days will be considered those on which there is business activity at the CAMARB unit corresponding to the location of the arbitration, dispute board, or mediation: Belo Horizonte, Brasília, Goiânia, Itajaí, Lisbon, Recife, Rio de Janeiro, Salvador, or São Paulo. Deadlines are continuous and are not suspended on days when there is no business activity at the respective CAMARB unit.

The deadline will be extended to the next business day if the due date falls on a day when the CAMARB unit corresponding to the location of the arbitration, dispute board, or mediation is closed: Belo Horizonte, Brasília, Goiânia, Itajaí, Lisbon, Recife, Rio de Janeiro, Salvador, or São Paulo. Similarly, if the location of the arbitration, dispute board, or mediation is different, or if the due date falls on an official holiday (municipal, state, or federal) in the respective location.
