Date Difference Formula

Days between dates:
  Δ days = End Date − Start Date

Weeks: Δ days / 7 (integer division + remainder)

Approximate months: Δ days / 30.44

Years + months + days:
  Full years: floor(Δ days / 365.25)
  Remaining months: ...
  Remaining days: ...

Add days to date:
  Result = Start Date + N days

Common Use Cases in Italian HoReCa

Use caseWhy days matter
TFR accrual (Italian severance)Exact days worked affect monthly accrual amount
Pro-rated 13th month (tredicesima)Paid in proportion to months worked in the year
Fixed-term contract (tempo determinato)Maximum 24 months (730 days) including renewals
Unpaid leave (aspettativa)Affects TFR and holiday accrual calculations
Food safety certification renewalCertificato HACCP valid for a fixed number of years

Example: Italian Fixed-Term Employment Contract Duration

A seasonal waiter (cameriere stagionale) at a coastal restaurant signs a fixed-term contract starting 15 June 2025 and ending 15 September 2025.

  • Days between dates: 92 days
  • Weeks: 13 weeks + 1 day
  • Months: 3 months exactly
  • TFR accrual: 92 / 365 × annual salary / 13.5
  • Pro-rata tredicesima: 3/12 of monthly salary

Direct answers

How do I calculate days between two dates?
Subtract the earlier date from the later date: Days = End Date − Start Date. Most calculators and spreadsheets do this automatically. In Excel/Google Sheets: =DATEDIF(A1,B1,"d") or simply =B1−A1 (formatted as a number).
Does the calculator include the start and end date?
By default, the calculator counts the days between dates (exclusive of both ends). For contract durations where both days count, add 1 to the result. This is common in Italian employment contracts (from the start date to the last day, inclusive).
How do I convert days to months and years?
Approximate conversion: 1 year ≈ 365.25 days, 1 month ≈ 30.44 days. For exact months (important for Italian TFR and accrual calculations), the calculator handles month boundary logic correctly.
Can I add days to a date?
Yes — the calculator also has an 'add days to date' mode. Useful for: calculating a contract end date, finding a deadline 30 days after signing, or determining when a fixed-term employment contract expires.
Why is this useful for Italian restaurant workers?
In Italian HoReCa employment (governed by CCNL Pubblici Esercizi), many calculations depend on exact days worked: TFR accrual, pro-rated 13th month (tredicesima), holiday entitlement, and temporary contract renewals all require accurate date arithmetic.
What is the difference between calendar days and working days?
Calendar days include weekends and holidays. Working days (giorni lavorativi) exclude Saturdays, Sundays and national holidays. Italian notice periods and some salary calculations use working days.
