Calcolatore di date
Calcola i giorni tra date o sposta una data avanti o indietro.
Calculate calendar-day differences and offsets
Use the date calculator to find the number of days between two dates or determine which date is a chosen number of days before or after another. It counts calendar days, including weekends, rather than working days or hours.
How to use this tool
- Choose Days Between and enter the From and To dates to see the distance between them.
- Choose Add / Subtract to shift a start date by a whole number of days.
- Select Add or Subtract and read the resulting calendar date. Use positive day counts with the chosen operation for clarity.
A practical example
January 1 to January 31 is 30 days apart. Adding 30 days to January 1 gives January 31. If you need a count that includes both endpoint dates, add one to the displayed distance.
Common questions
Does the result include the start date?
The result is the distance between dates: identical dates give zero, and consecutive dates give one. It is not an inclusive count of every date listed from start through finish.
Does it exclude weekends or public holidays?
No. Every calendar day counts. The calculator has no business-day mode and does not apply country-specific holidays. Reversing the dates still shows the positive distance between them.
Are leap days included?
Yes. Calendar arithmetic includes February 29 when the selected interval crosses a leap day. The calculation uses date-only UTC values so a seasonal clock change does not turn a calendar day into a fractional result.
