Court Deadline Calculator — Due Dates, Summer Suspension and Backward-Counted Deadlines
Calculator
Court Deadline Calculator
Calculate the due date of an Italian civil procedure deadline, counting forward or backward, with the summer suspension, public holidays and extension to the next non-holiday
The calculator applies art. 155 c.p.c. (Italian Code of Civil Procedure: first day excluded, ordinary calendar for months and years, extension to the next non-holiday also when the deadline falls on a Saturday for acts performed outside the hearing), art. 2963 c.c. (Italian Civil Code) when the month of expiry lacks the corresponding day, and the summer suspension from 1 to 31 August (L. 742/1969). For backward-counted deadlines, bringing forward a due date that falls on a Saturday or a public holiday follows a well-established line of case law, not a written rule. Only national public holidays are taken into account: the local patron saint's day must be entered manually. This is an informational tool and does not replace the lawyer's check on the individual case file.

How the calculation of court deadlines works
This court deadline calculator finds the due date of an Italian civil procedure deadline starting from a reference date — service or publication of a judgment, date of the hearing — and a duration in days, months or years. The count runs forward (thirty days from service for an appeal) or backward, as for briefs to be filed “at least forty days before the hearing”. Besides the date, you get the days counted, those skipped because of the summer suspension and a step-by-step explanation. The calculation runs in your browser.
The rules applied
| Rule | Provision | Example |
|---|---|---|
| First day excluded, last day included | Art. 155, paragraph 1 c.p.c. | 10 days from 1 September → 11 September |
| For months and years the ordinary calendar applies | Art. 155, paragraph 2 | 6 months from 20 February → 20 August |
| If the corresponding day is missing, the last day of the month applies | Art. 2963, paragraph 4 c.c. | 1 month from 31 January → 28 February |
| Holidays within the period are counted | Art. 155, paragraph 3 | Intermediate holidays do not extend anything |
| Due date on a holiday: extended to the next non-holiday | Art. 155, paragraph 4 | 25 December → next working day |
| The extension also applies to Saturdays, for acts performed outside the hearing | Art. 155, paragraph 5 | Saturday → Monday |
The summer suspension (art. 1 of law 742/1969) stops the running of deadlines from 1 to 31 August: 31 days, no longer the 46 of the past, following D.L. 132/2014. If the deadline starts in August, the start is postponed and the count begins on 1 September; for month-based deadlines spanning August, the Court of Cassation adds the 31 days to the deadline calculated by the ordinary calendar (order no. 7114/2024).
Backward-counted deadlines are a special case: if the due date calculated backward falls on a Saturday or a public holiday, it is not extended forward but brought forward to the first preceding non-holiday, so as not to shorten the interval guaranteed to the other party. This is not a written rule: it is a well-established line of case law (Cass. civ. sez. III order no. 23634/2025), and the calculator states it in the relevant step.
Holidays taken into account
The national public holidays for civil purposes are built in (art. 2 of law 260/1949, with 6 January from DPR 792/1985 and 2 June from law 336/2000), as well as all Sundays: 1 and 6 January, Easter, Easter Monday, 25 April, 1 May, 2 June, 15 August, 4 October (from 2026, law 151/2025), 1 November, 8, 25 and 26 December. Easter is calculated with Meeus's Gregorian algorithm. 4 November has not been a holiday since 1977. The patron saint's day varies from municipality to municipality: enter it in the optional field.
Calculation examples
| Case | Settings | Steps | Due date |
|---|---|---|---|
| 30 days from service | 22 July 2026 · 30 days · forward · suspension | From 23 to 31 July 9 days accrue; the 31 days of August are not counted; from 1 September the remaining 21 | Monday 21 September 2026 |
| First brief under art. 171-ter c.p.c. | Hearing 12 October 2026 · 40 days · backward · suspension | Count back 40 days from the hearing, which is excluded; the period does not touch August; the 40th day is neither a Saturday nor a holiday | Wednesday 2 September 2026 |
| Long time limit for appeal | 20 February 2026 · 6 months · forward · suspension | By the ordinary calendar you would reach 20 August; +31 days of suspension up to Sunday 20 September, extended because it is a Sunday | Monday 21 September 2026 |
The pre-filled deadlines
The menu only contains deadlines with an explicit legal source. Forward: 30 days for appeal, revocation and third-party opposition and 60 days for an appeal to the Court of Cassation (art. 325 c.p.c.); 6 months for the long time limit (art. 327 c.p.c.). Backward: the three supplementary briefs under art. 171-ter c.p.c., at least 40, 20 and 10 days before the hearing; and the deadlines of the decision phase under art. 189 c.p.c., namely 60 days for the notes specifying the final submissions, 30 for the closing brief and 15 for the reply.
If you are looking for the “art. 183 deadline calculation” or the “art. 190 deadline calculation”, you are looking at the framework prior to the riforma Cartabia (Cartabia reform): the briefs under art. 183, paragraph 6 and the closing briefs under art. 190 c.p.c. apply to proceedings started up to 28 February 2023; for later ones, arts. 171-ter and 189 apply. For cases governed by the old rules, set duration and direction manually.
When the summer suspension does not apply
Untick the box when the proceedings fall among those excluded by art. 3 of law 742/1969, which refers to art. 92 of the judicial system law: employment and social security, maintenance, interim relief proceedings, support administration, incapacitation, protection orders, evictions and oppositions to enforcement, bankruptcy proceedings and in general cases whose delayed handling may cause serious harm to the parties. In borderline matters the classification depends on the specific case, so the list is not built in.
The tool covers ordinary civil computation: it does not know extraordinary suspensions or the special rules of criminal and administrative proceedings, and it does not assess whether the deadline is mandatory or merely directory. Verifying timeliness remains the responsibility of the lawyer.
Frequently asked questions
How are court deadlines calculated under art. 155 c.p.c.?
The first day is not counted, the last day is. Deadlines in months or years follow the ordinary calendar and expire on the day with the same number in the month of arrival; if that day does not exist, the last day of the month applies. Intermediate holidays are counted, but if the due date falls on a public holiday it is extended to the next non-holiday, and the same applies to Saturday for acts performed outside the hearing.
How does the calculation of backward-counted deadlines work?
You start from the future reference date, typically the hearing, which is not counted, and go back by the prescribed number of days: this is how you find the due dates of briefs to be filed at least X days before. If the date found falls on a Saturday or a public holiday, you do not move to the following Monday but bring it forward to the first preceding non-holiday. This is a well-established line of case law, not a rule written in art. 155 c.p.c.
How long does the summer suspension of deadlines last?
From 1 to 31 August each year, i.e. 31 days: this is provided by art. 1 of law 742/1969 as amended by D.L. 132/2014, which shortened the period compared with the previous 46 days up to 15 September. The days of August are not counted and, if the period starts during that time, the count begins on 1 September. The suspension does not apply to several matters, including employment, social security, maintenance and interim relief proceedings.
What are the deadlines for the supplementary briefs after the riforma Cartabia?
Art. 171-ter c.p.c. provides for three supplementary briefs to be filed, on pain of forfeiture, at least 40, 20 and 10 days before the hearing referred to in art. 183. In the decision phase, art. 189 c.p.c. sets deadlines of no more than 60 days before the referral hearing for the notes specifying the final submissions, 30 for the closing briefs and 15 for the reply briefs. They apply to proceedings started after 28 February 2023.
