Business Days in September 2026 for Italy

September 2026 has 22 giorni lavorativi under the Italian national holiday calendar. The month spans 30 calendar days, of which 8 fall on a weekend and 0 are Italian national holidays that lands on a weekday. The remaining 22 weekdays are countable as giorni lavorativi for invoicing, deadline tracking, and contract math.

September 2026 contains no Italian national holidays that fall on a weekday. Banks, the central clearing system, and Italy financial markets keep their normal schedule throughout the month under this calculator's national-only holiday set.

Yes. Santo Stefano (December 26) is a national festività in Italy alongside Natale (December 25). Both close banks, Borsa Italiana, and most private-sector employers. The Italian national set differs from many other countries by including December 26 universally as a public holiday, alongside Catholic-rooted dates such as Immacolata Concezione (December 8) and Ognissanti (November 1) that are also fully national.

Each Italian municipality observes its own Festa del Patrono (patron saint's day): San Giovanni Battista in Florence on June 24, San Petronio in Bologna on October 4, Sant'Ambrogio in Milan on December 7, and others. These are local holidays that close municipal offices, schools, and some businesses in their respective cities but are not in this national set. For Milan-, Rome-, or Florence-specific contracts, layer the municipal patron-saint date under the calculator's Advanced options.

Two things shift the monthly count for Italy. First, the day of the week the first of the month lands on changes the count of each weekday. Second, Italian national holidays anchored to a fixed date shift their weekday across years. Some years a fixed-date holiday lands on a weekend; some countries shift the observance to an adjacent weekday and some absorb it into the weekend. September 2025 also had 22 giorni lavorativi, so the working capacity is unchanged year over year.
