festività nazionali in May 2027

No Italian national holidays fall on a weekday in May 2027, so the month loses no working day to a holiday on this calendar.

Italy May deadlines

The Festa del Lavoro on 1 May is a giorno festivo. The F24 for April falls due on the 16th. The Modello Redditi PF is filed telematically between 15 April and 31 October, not in November.

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 May 2027 compares year over year

May 2026 had 20 giorni lavorativi, so May 2027 has 1 more working day year over year. On the surrounding months, April 2027 has 22 giorni lavorativi and June 2027 has 21. Looking forward, May 2028 has 22 giorni lavorativi under the same Italian national holiday calendar.

Using this calculator in Italy

A Milan corporate controller uses the 21-day May 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 May 2027 is shaped

The headline count answers how many giorni lavorativi May 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.

The middle month of the second quarter

May runs 31 days and sits in the middle of Q2, the position with neither a quarter opening nor a quarter close to anchor it. It shares its weekday alignment with January in a common year, so the two months carry the same underlying structure twelve months apart. A 31-day month always carries three weekdays five times, which is what makes its working-day count the most sensitive of the four month lengths to where it starts.

In May 2027 that comes to 21 giorni lavorativi across 31 calendar days, against 22 in April 2027 and 21 in June 2027.

The month opens across a weekend

The 1st of May is a Saturday, a weekend day under the Italian national calendar, whose week runs against a sabato and domenica weekend. Nothing that settles on working days moves on it. A month that opens this way loses its first working day to the calendar before any holiday is counted, and monthly cycles keyed to the 1st all resolve forward to the same date, which concentrates them.

The month's first working day is Monday, May 3, and May 2027 carries 21 giorni lavorativi in total.

Five working stretches

May 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 May 2027 arrive in stretches of 5, 5, 5, 5, and 1 day. The longest unbroken stretch runs five days, from May 3 to May 7. 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 front-loaded. It opens with five consecutive days and closes with one, so capacity thins toward the end. Work deferred out of the first stretch arrives in a shorter one, which is how a schedule that looked comfortable in week one stops fitting.

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 May 2027 the three are Sunday, Monday, 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 Monday 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.

Every holiday this month falls on the weekend

May 2027 does contain an Italian national holiday, but it lands on the weekend (sabato and domenica under this calendar): Festa del Lavoro on Saturday, May 1. A holiday costs a working day only when it displaces one, so a weekend-falling holiday leaves the month's count untouched.

Whether the day off is recovered on an adjacent weekday depends on the substitution rule of the jurisdiction, which varies and is not assumed here. This calculator counts only the dates its holiday data publishes, and for May 2027 that data lists no Italian national closure on a working day. Where a substitute weekday is granted, the data set carries it as a separate entry with its own date.

A closure sits just outside the month

May 2027 contains no Italian national closure of its own, but one sits within a week of its edge. A closure just outside a month still reaches into it: work displaced from the closed day lands on the working days beside it, and those are inside May whichever side the holiday falls on.

Looking outside the month, the last was Lunedì dell'Angelo on March 29, 2027, 33 calendar days before May began and the next is Festa della Repubblica on June 2, 2027, 2 calendar days after it ends.

Across the whole of 2027 the Italian national calendar puts seven closures on working days, of which none falls in May. 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 where a week begins

The final calendar day of May 2027 is the first working day of a week. A single working day of that week belongs to May and the rest to the month following, which is the least amount of closing capacity a month can have. Anything that must be done "in the last week" of May really has to be done before the preceding weekend.

The last working day of May 2027 is Monday, May 31. Counting back from there, the third-to-last is Thursday, May 27, four calendar days before the month closes.

The middle month of the quarter

May is the middle month of Q2. Middle months carry the least visibility in a quarterly cycle: the opening month sets expectations and the closing month is where they are settled, so a shortfall here is the one most likely to be noticed late.

Across the whole quarter there are 64 giorni lavorativi, of which 21 fall in May. The other two months carry April 2027 with 22 and June 2027 with 21. It sits between the other two, which makes it the month where a quarterly plan is least likely to be thrown off by the calendar alone.

The week's second working day is the scarcest

The second working day of the week is the one May gives least often. Weekly cycles that run one day behind the start of the week, which is where most reporting handovers sit, lose an occurrence relative to the rest.

Counted as worked rather than as occurring, May 2027 gives Monday 5, Tuesday 4, Wednesday 4, Thursday 4, and Friday 4. 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.

Where the month sits in the year

May sits in the middle of 2027 by working-day count under the Italian national calendar. The middle of that ranking is where a month's total is least informative on its own, because a mid-ranked month can be a long month carrying closures or a short one carrying none, and the two need different plans.

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. May ranks 7th of the twelve with 21.

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.

One working day more than last year

There is one more giorni lavorativi in May 2027 than in May 2026: 21 against 20. A single-day swing is the ordinary case, produced by the calendar shifting forward one weekday between consecutive common years, and it is large enough to matter to a monthly target and small enough to be missed.

May opens 2026 on a Friday, 2027 on a Saturday, and 2028 on a Monday. 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, May 2028 carries 22 giorni lavorativi.

Where the month's anchor dates fall

Two of the common monthly anchor dates in May 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 May 2027

An invoice dated the 1st of May on calendar-day Net 30 terms comes due on May 31, 2027, a working day under the Italian national calendar. Terms counted in calendar days move independently of the working week, so the same term written on two consecutive months can settle cleanly in one and roll across a closure in the other.

Invoice dateNet 30, calendar daysNet 60, calendar days
Dated May 1May 31, 2027June 30, 2027
Dated May 15June 14, 2027July 14, 2027
Dated May 31June 30, 2027July 30, 2027

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 May 2027 under the Italian national holiday calendar?
May 2027 has 21 giorni lavorativi under the Italian national holiday calendar. The month spans 31 calendar days, of which 10 fall on a weekend and 0 are Italian national holidays that land on a weekday. The remaining 21 weekdays are countable as giorni lavorativi for invoicing, deadline tracking, and contract math.
Which Italy holidays affect May 2027?
May 2027 contains no Italian national holidays that fall on a weekday, so on this calculator's holiday set the month loses no working day.
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. May 2026 had 20 giorni lavorativi, so May 2027 has 1 more working day year over year.
When is the last working day of May 2027?
The last working day of May 2027 under the Italian national calendar is Monday, May 31. The month's last calendar day is Monday, May 31, so the two are the same date this year. Counting back, the third-to-last working day is Thursday, May 27.
How many working days in a row does May 2027 offer?
May 2027 has 21 giorni lavorativi in total, but they do not run consecutively. They arrive in five stretches of 5, 5, 5, 5, and 1 day, so the longest unbroken run is five days, from May 3 to May 7. No working day in the month is isolated between two closures.
