festività nazionali in October 2027

Mon, Oct 4San Francesco d'Assisi

Italy October deadlines

October gained a national holiday. Legge 151/2025 inserted 4 October, the festa nazionale di San Francesco d'Assisi, into the list of giorni festivi with effect from 1 January 2026; because 4 October 2026 falls on a Sunday, the first year it removes a working day is 2027. The F24 for September falls due on the 16th, and 31 October closes the telematic filing window for the Modello Redditi, for individuals and for companies whose tax period ended in December. The Bollettino economico publishes this month.

Italy reporting cycles and business-day rules

Italian business-day cycles run on the F24, which carries withholding and the monthly liquidazione IVA and falls due on the 16th of the following month; where the 16th is a Saturday or a holiday, payment is timely on the first working day after it. Anything falling due between 1 and 20 August may be settled by 20 August with no surcharge, which is a standing rule and not an annual concession. Filing and payment are separate obligations and the dates differ: the Modello Redditi is filed telematically between 15 April and 31 October, for individuals and for companies whose tax period ends in December, while the balance and the first advance instalment fall due on 30 June, or thirty days later with a 0.40 per cent uplift, and the second advance instalment falls in November. The Certificazione Unica goes to the people it covers by 16 March. Euro wholesale settlement runs on T2, which TARGET2 became in March 2023, and Banca d'Italia continues to operate BI-Comp for retail clearing.

How October 2027 compares year over year

October 2026 had 22 giorni lavorativi, so October 2027 has 2 fewer working days year over year. On the surrounding months, September 2027 has 22 giorni lavorativi and November 2027 has 21. Looking forward, October 2028 has 21 giorni lavorativi under the same Italian national holiday calendar.

Using this calculator in Italy

A Milan corporate controller uses the 20-day October 2027 count to line T2 settlement up with the F24 deadline on the 16th, and to see where that 16th rolls onto the first following working day. A Rome law firm counts giorni lavorativi against D.Lgs. 231/2002, which caps commercial payment at 30 days unless a longer period is expressly agreed and provable in writing, and against INPS contribution cycles: ENPALS was suppressed in 2012 and its functions passed to INPS. A Florence manufacturing controller uses the count to separate the Certificazione Unica, delivered to employees by 16 March, from the Modello Redditi filing window that closes on 31 October.

How October 2027 is shaped

The headline count answers how many giorni lavorativi October 2027 contains. It does not answer where they sit, and for anything measured in consecutive days rather than cumulative days that second question is the binding one. What follows is derived entirely from the Italian national holiday calendar and a working week that treats sabato and domenica as the weekend, with no assumption about how any particular obligation behaves.

A 31-day month opening the final quarter

October runs 31 days and opens Q4, the last quarter of the calendar year, so everything deferred earlier arrives inside a period that begins here. It shares its weekday alignment with January in a common year. As a 31-day month it carries three weekdays five times, and which three is decided entirely by the day it opens on.

In October 2027 that comes to 20 giorni lavorativi across 31 calendar days, against 22 in September 2027 and 21 in November 2027.

The month opens on the last day of a working week

October 2027 starts on the final working day of a week. One working day stands between the 1st and the weekend, so the month's real momentum does not begin until the following week. This is the start that most compresses a monthly plan: the calendar has turned, but only one working day has passed before the first closure.

The month's first working day is Friday, October 1, and October 2027 carries 20 giorni lavorativi in total.

Five working stretches

October splits into five working stretches. That is the ordinary shape of a month whose only interruptions are its weekends, and it means the month's internal boundaries are all predictable a year in advance: nothing here depends on a holiday date moving.

The working days of October 2027 arrive in stretches of 1, 4, 5, 5, and 5 days. The longest unbroken stretch runs five days, from October 11 to October 15. A task needing more consecutive giorni lavorativi than that cannot be completed inside a single stretch, whatever the month's total looks like.

The month is back-loaded. It opens with one consecutive day and closes with five, so the room is at the end rather than the start. That is the safer of the two imbalances, because a slip has somewhere to go, but it also makes the opening week a poor sample of the month.

Three weekdays occur five times

A 31-day month contains four full seven-day cycles and three days over, so exactly three weekdays occur five times and the other four occur four times. In October 2027 the three are Sunday, Friday, and Saturday. Which three it is follows entirely from the weekday the month opens on, which is why the working-day count of a 31-day month moves year to year even when its holidays do not.

Only Friday among them is a working day, so part of the surplus is absorbed by the sabato and domenica weekend and never reaches the working total. That split is why two months of the same length can carry different working-day counts without any holiday being involved.

One closure, and where it lands

October 2027 carries a single Italian national closure on a working day: San Francesco d'Assisi on Monday, October 4. A holiday's cost to a month is not only the day it removes; it is also where the removal falls, because the same closure can extend an existing break or cut a working stretch in half.

It sits directly beside a weekend rather than inside a working week, so it extends an existing break instead of creating a new one. That is the cheapest position a holiday can occupy: the month loses a day but keeps its shape.

Exactly one working day passes before the closure. A single day of runway is not enough to start anything that has to continue, so in practice the month begins after the break rather than before it.

The closures around this month

October 2027 carries one Italian national closure of its own, and the months on either side add their own. Where a deadline sits close to a month boundary, the closure that moves it is as likely to be outside the month as inside it.

Looking outside the month, the last was Festa della Repubblica on June 2, 2027, 121 calendar days before October began and the next is Ognissanti on November 1, 2027, 1 calendar day after it ends.

Across the whole of 2027 the Italian national calendar puts seven closures on working days, of which one falls in October. That ratio, rather than the raw count, is what tells you whether a month is carrying more than its share of the year's downtime.

The month ends over a weekend

October 2027 ends on a Sunday, which this calendar treats as weekend. Month-end processing cannot happen on the last calendar day, so it happens earlier and the last few dates of the month carry no settlement at all. The distance between the final working day and the final calendar day is where month-end reconciliations go missing.

The last working day of October 2027 is Friday, October 29. Counting back from there, the third-to-last is Wednesday, October 27, four calendar days before the month closes.

The working month ends on the last working day of a week, so the final stretch is a complete one and nothing is left hanging mid-week. Two calendar days of October follow it with nothing settling on them.

The quarter opens here

October is the first month of Q4. An opening month sets the baseline the rest of the quarter is measured against, and it is the one month where a slip has two further months to be absorbed in. Quarterly targets divided evenly by three ignore the fact that the three months rarely carry equal working-day counts.

Across the whole quarter there are 63 giorni lavorativi, of which 20 fall in October. The other two months carry November 2027 with 21 and December 2027 with 22. It is the smallest of the three, so the quarter's capacity sits mostly in the other two months and a plan that spreads work evenly across the quarter will over-commit October.

The week's first working day is the scarcest

The first working day of the week is the one October gives least often. Anything anchored to the start of the working week (a weekly kickoff, a Monday-morning cutoff, a start-of-week batch) fires fewer times this month than the calendar count suggests, because a closure has taken one of them out.

Counted as worked rather than as occurring, October 2027 gives Monday 3, Tuesday 4, Wednesday 4, Thursday 4, and Friday 5. A weekly commitment pinned to a particular weekday fires that many times in the month, which is the number a rota needs and not the one the calendar shows.

Toward the short end of the year

October sits among the shorter working months of 2027 under the Italian national calendar. A month reaches this end of the ranking either by being short or by absorbing closures, and the two produce the same headline number while behaving differently: a closure fragments the month, a shorter calendar does not.

2027 carries 254 giorni lavorativi in total under the Italian national calendar. The longest month of the year is March 2027 with 22 and the shortest is January 2027 with 19, a spread of 3. October ranks 11th of the twelve with 20.

Italy closures across the year

A month's working-day count only means something against the country's whole calendar. Two countries that share a weekend and happen to have the same closure-free month can still run very different years, and Italy is placed as follows.

Across 2027 the Italian national closures fall 3 in Q1, 1 in Q2, 0 in Q3, and 3 in Q4. A further five holidays land on the sabato and domenica weekend and cost no working day at all, which is why a country's holiday count and its working-day loss are different numbers.

The longest uninterrupted run in the 2027 calendar sits between June 2, 2027 and October 4, 2027, 124 calendar days with no Italian national closure in between. Stretches like that are where multi-week work belongs, and they move from year to year whenever a movable holiday does.

Where the month sits in the year's closure pattern

Closures are not spread evenly across a calendar year. They cluster around fixed anniversaries and around whichever lunar or movable feasts a jurisdiction observes, so two adjacent months can carry very different loads, and the Italian national calendar is no exception.

2027 opens its Italian national closures with Capodanno on January 1, 2027 and ends them with Immacolata Concezione on December 8, 2027. The densest month of the year is January 2027 with two closures on working days.

A materially shorter month than last year

October 2027 carries 2 fewer giorni lavorativi than October 2026 did (20 against 22). Two or more days is a large swing between adjacent years and it takes both causes acting together: the weekday alignment moving and a closure changing which side of a weekend it falls on.

October opens 2026 on a Thursday, 2027 on a Friday, and 2028 on a Sunday. That movement, one weekday in a common year and two after a leap day, is what makes the three counts differ. The count of closures on working days differs between the two years as well, so alignment is not the only thing moving. Looking ahead, October 2028 carries 21 giorni lavorativi.

Where the month's anchor dates fall

Two of the common monthly anchor dates in October 2027 land outside the working week or on a closure. The table below resolves each one against the Italian national calendar, together with the first working day on or after it.

The final column is arithmetic, not a legal conclusion. Whether an obligation actually moves when its date is not a working day depends on the instrument that sets it, and this site does not assume a shift rule for any jurisdiction. Where a rule is known it is stated in the holiday data methodology and on the country page it applies to.

Net terms dated in October 2027

An invoice dated the 1st of October on calendar-day Net 30 terms comes due on October 31, 2027, which is not a working day under the Italian national calendar. A term counted in calendar days can land anywhere in the week, and roughly two days in seven it lands somewhere nothing settles, which is the ordinary reason a payment shows as late by a day or two without anyone being late.

Invoice dateNet 30, calendar daysNet 60, calendar days

Net 30 and Net 60 are commercial conventions rather than statutory periods, and both are counted here in calendar days, which is how they are almost always written. Where a contract counts in working days instead, use the between-dates calculator with the Italy calendar selected, because the two produce different dates whenever a closure falls inside the term.

Frequently Asked Questions

How many business days are in October 2027 under the Italian national holiday calendar?
October 2027 has 20 giorni lavorativi under the Italian national holiday calendar. The month spans 31 calendar days, of which 10 fall on a weekend and 1 is an Italian national holiday that lands on a weekday. The remaining 20 weekdays are countable as giorni lavorativi for invoicing, deadline tracking, and contract math.
Which Italy holidays affect October 2027?
October 2027 contains one Italian national holiday: San Francesco d'Assisi on Monday, October 4. The calculator skips it. Regional or industry-specific closures may add further non-working days for narrower contract definitions; layer them into the calculator's Advanced options if needed.
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.
Why does the business-day count vary year to year?
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. October 2026 had 22 giorni lavorativi, so October 2027 has 2 fewer working days year over year.
When is the last working day of October 2027?
The last working day of October 2027 under the Italian national calendar is Friday, October 29. The month's last calendar day is Sunday, October 31, which is not a working day, so month-end processing has to happen two calendar days earlier than the calendar suggests. Counting back, the third-to-last working day is Wednesday, October 27.
How many working days in a row does October 2027 offer?
October 2027 has 20 giorni lavorativi in total, but they do not run consecutively. They arrive in five stretches of 1, 4, 5, 5, and 5 days, so the longest unbroken run is five days, from October 11 to October 15. No working day in the month is isolated between two closures.
