How Date Differences Work
The number of days between two dates is calculated by converting each date to a timestamp and finding the difference. The result accounts for varying month lengths and leap years automatically.
Working Days
Working days (also called business days) are Monday through Friday, excluding weekends. This calculator counts all weekday occurrences between the two dates — it does not account for public holidays, which vary by country.
