Italy Business Day Calculator

Last reviewed: October 14, 2026 · Holiday data: September 10, 2026

Calculate giorni lavorativi in Italy with the festività nazionali preselected, including Santo Stefano (26 December) and San Francesco d'Assisi (4 October), a national holiday from 2026. Use it for working-day counts around F24 payments, the Certificazione Unica, Modello Redditi filings and T2 settlement.

How Italy Business Days Are Defined

In Italy, working days are the days of the week outside the sabato and domenica weekend, minus the festività nazionali listed below. The exchange keeps its own calendar: in 2026 Borsa Italiana closes all its markets on four of these holidays (1 January, Lunedì dell'Angelo, 1 May and 25 December) and also on Venerdì Santo, which is not a public holiday, and on 24 and 31 December.

Italy Public Holidays

The major festività nazionali are:

  • Capodanno (1 gennaio)
  • Epifania (6 gennaio)
  • Lunedì dell'Angelo (variabile)
  • Festa della Liberazione (25 aprile)
  • Festa del Lavoro (1 maggio)
  • Festa della Repubblica (2 giugno)
  • Ferragosto (15 agosto)
  • San Francesco d'Assisi (4 ottobre)
  • Ognissanti (1 novembre)
  • Immacolata Concezione (8 dicembre)
  • Natale (25 dicembre)
  • Santo Stefano (26 dicembre)

Decreto Legislativo 231/2002 caps commercial payment at 30 days unless a longer period is expressly agreed and provable in writing, and never above 60 days against a public administration. Its own title transposes Directive 2000/35/EC; Directive 2011/7/EU arrived through the amending Decreto Legislativo 192/2012. Statutory default interest runs at the ECB main refinancing rate plus 8 percentage points, with a fixed 40 euro recovery amount. The Late Payment Interest Calculator handles the interest math; the Invoice Due Date Calculator stages 30 and 60-day payment terms against the festività nazionali calendar.

Frequently Asked Questions

Which holidays are included for Italy?
The calculator preselects the festività nazionali listed in article 2 of Legge 27 maggio 1949, n. 260, including the 4 October holiday inserted by Legge 151/2025 from 1 January 2026. Dates for every year from 2024 to 2029 are loaded into the calculator. Use the Advanced options to layer any municipal patron-saint or industry-specific dates that apply to a particular contract.
What is the Italy workweek?
This calculator counts sabato and domenica as Italy's weekend and also leaves out the listed public holidays, so a count runs Monday to Friday.
Is Santo Stefano (December 26) observed as a national holiday in Italy?
Yes. Article 2 of Legge 260/1949 lists 26 December among the giorni festivi, alongside Natale on 25 December, Immacolata Concezione on 8 December and Ognissanti on 1 November. From 1 January 2026 the same list also carries 4 October, the festa nazionale di San Francesco d'Assisi added by Legge 151/2025. A public holiday and a market closure are not the same thing, though: the Borsa Italiana calendar for 2026 closes all its markets on 24, 25 and 31 December but not on 8 December, when only its After Hours market is closed, and it closes them on Venerdì Santo, which is not an Italian public holiday at all.
How does the Festa del Patrono affect this national calendar?
A patron saint's day is not a national holiday. Legge 90/1954 treats the celebration of the Santo Patrono of the locality where the work is performed as a circumstance distinct from the national festività, so it binds by locality and by the applicable agreement rather than across the country. This calculator carries the national set only. For a contract tied to one city, add that municipality's patron date under the calculator's Advanced options. One overlap is worth flagging from 2026 onwards: 4 October is now a national holiday in its own right, whatever a given municipality already did with the date.
