Date Difference
- Enter the start and end dates.
- Choose a country for holiday calculation, or leave it unset to count weekends only.
- The result gives total days, business days, weekend days and holidays, plus the difference in years, months and days.
Calendar days count everything. Business days exclude Saturdays, Sundays and the holidays of the chosen country.
The distinction is decisive for contractual and legal deadlines: 30 calendar days and 30 business days can finish more than two weeks apart.
Movable holidays, such as those tied to Easter, are computed per year rather than read from a fixed list — otherwise the result would be wrong outside the reference year.
Municipal holidays and discretionary days off are not included: they vary by city and by administrative decision, and no reliable national list exists.
The years, months and days figure is a calendar breakdown, not a division of the total. Months run from 28 to 31 days, so turning 45 days into "1 month and 15 days" depends on which months were crossed.
It is the same reason a person’s age is not the total days divided by 365: leap years and variable month lengths make that arithmetic approximate.
For deadlines, use the total day count. For expressing duration in natural language, use the breakdown.
