How business days are counted

- Adding business days: counting starts on the first business day after the start date, as with legal and banking deadlines in Brazil.
- Saturdays, Sundays and Brazilian national holidays are not business days.
- Holidays used: this calculator only knows the national holidays of Brazil. Public holidays of other countries are not taken into account.
