Date calculator
Three calculators in one: days (and weekdays) between two dates, exact age, and adding or subtracting days from a date.
Days between two dates
Age calculator
Add / subtract days
What is it for?
Counting down to an event, a deadline or a holiday; measuring the exact length of a contract; working out a precise age in years, months and days; or finding what date it will be in 30, 60 or 90 days.
Weekday counting (Monday to Friday) is included — handy for administrative or business deadlines.
FAQ
Does the start day count in the result?
No: the tool counts elapsed days between the two dates. From the 1st to the 3rd, that is 2 days.
Are public holidays taken into account?
No, only weekends are excluded from the weekday count. Public holidays vary by country and year.
Can I subtract days from a date?
Yes: in “Add / subtract days”, enter a negative number (e.g. -15).
