The 261 working days shown above are the 365 calendar days of 1970, minus the 104 Saturdays and Sundays, minus the 0 public holidays that land on a weekday. Holidays that fall on a Saturday or Sunday are not subtracted, because they do not remove a day anyone would have worked; in 1970 that applies to 0 of Portugal's public holidays. At a standard eight-hour day, 261 working days works out to roughly 2,088 working hours across the year, before any annual leave is taken.
Article 279 of the Código Civil and article 138 of the Código de Processo Civil define dia útil as any day not a Saturday, Sunday or public holiday. The standard private-sector week is Monday to Friday with banks operating Monday to Friday. Statutory annual leave under the Código do Trabalho article 238 is 22 working days plus the thirteen public holidays. Settlement of euro transactions uses TARGET2; domestic Portuguese banking follows the Banco de Portugal calendar, which observes the eight obligatory national days plus the Lisbon municipal holiday only for the Lisbon-cleared instruments.
Portugal has thirteen public holidays under article 234 of the Código do Trabalho, eight obligatory national plus Easter Sunday (movable) plus optional regional and municipal observances. The Madeira and Azores autonomous regions add their own statutory days, including Madeira Day on 1 July and Azores Day on the Monday after Pentecost. Each município adds its own municipal holiday, typically the patron saint's day, so Lisbon closes for Saint Anthony on 13 June and Porto for Saint John on 24 June. Four national holidays were suspended between 2013 and 2016 as an austerity measure under the IMF and EU bailout, then restored by Law 8/2016.
This matters because the working-day total is not spread evenly. Some months in Portugal carry several public holidays while others have none, so the month-by-month table above is the figure to use for payroll runs, billing cycles, SLA windows, and project plans rather than a flat assumption of about 21.8 working days per month. A month with two weekday holidays can have several fewer working days than a clear one, which changes capacity planning and the realistic delivery date for anything scheduled in business days.
To see the individual dates, the day of the week each holiday lands on, and the full official list, open the Portugal holiday calendar for 1970. You can subscribe to those dates as an .ics feed so they appear in your own calendar, or use the working-days-between-two-dates calculator to count business days for a specific date range rather than the whole year.
Working-day figures are computed from the public holiday list for Portugal (source: Nager.Date and the national references above) combined with a Monday-to-Friday business week. Regional holidays and substitute-day rules vary; confirm against the official calendar for legal or payroll use.
