Covers Brazil's 12 national public holidays, computed algorithmically for any year. Good Friday and Corpus Christi are Easter-based and calculated for any year. Carnival Monday and Tuesday are approximate dates from lunar-override tables — update for years beyond 2027. State and municipal holidays vary significantly and are not included.
Formula
Working Days = Weekdays − National holidays falling on weekdays
Count all Monday–Friday days in the range, then subtract Brazilian national holidays that fall on those weekdays. Carnival Monday and Tuesday are not official national holidays but are included by default since the vast majority of Brazilian businesses treat them as non-working days.
Worked Example
Scenario: A São Paulo supplier quotes a 10 working day delivery window starting Monday 3 March 2025.
Carnival Monday (3 March) and Carnival Tuesday (4 March) fall immediately at the start of the window.
10 working days + 2 Carnival days = 12 weekdays forward
Result: deadline falls on 17 March 2025
Many Brazilian contracts specify "úteis" (working days) or "corridos" (calendar days). Ensure you and your counterparty agree on which definition applies before the contract is signed.
Common Mistakes
- Ignoring Carnival. Carnival Monday and Tuesday are not official national holidays but represent one of the most commercially significant closure periods in Brazil — particularly in Rio de Janeiro, Salvador, Recife, and São Paulo. Most businesses close or operate with minimal staff. Deadlines set for the Carnival period routinely miss.
- Forgetting state and municipal holidays. Brazil has 26 states plus the Federal District, each with its own state holidays. São Paulo State Day (25 January), Founding of Rio de Janeiro (1 March), and many others add non-working days on top of the 12 national ones. Always ask your Brazilian counterparty about their specific state's holidays for deadline-critical work.
- Confusing "dias úteis" and "dias corridos" in contracts. Brazilian law and contracts frequently distinguish between "dias úteis" (working days, excluding weekends and holidays) and "dias corridos" (consecutive calendar days, including weekends). Misreading which definition applies can shift a payment or delivery deadline by several days.
