Add business days to a date, by municipality

The date a number of business days after a date (or before it, with a negative number) in a Portuguese municipality. The start date never counts; with 0 days, the date itself when it is a business day, otherwise the next one.

Rest days
Optional holidays

In the private sector, Carnival Tuesday and the municipal holiday are optional holidays (Labour Code, article 235): they are days off only when the employment contract or the collective agreement provides for them. By default, as in the API, the municipal holiday counts and Carnival does not.

How it calculates

The tool makes the calculation of the Calendas API, on the same data: the national holidays, the regional ones in the Azores and Madeira, and the municipal holiday of the municipality, each with the source it rests on. The free tool calculates between 2025 and 2027, at most 2 calendar years at a time.
