Date Difference Calculator
Pick two dates and instantly see the time between them — in days, weeks, months or a full breakdown, business days included.
Common uses
Counting down to a holiday or deadline, working out a project's duration, checking how long a warranty or trial period lasts, calculating tenure for a job application, or finding how many working days a contract spans. Both orders work — the tool always returns a positive duration, and business days exclude Saturdays and Sundays.
Frequently asked questions
Is the end date included?
The total counts full days elapsed between the two dates (start date at midnight to end date at midnight). For example, Sep 1 → Sep 8 is 7 days. Add 1 yourself if you need to include both endpoints, e.g. for hotel stays.
What are business days?
Monday through Friday, excluding weekends. Public holidays vary by country and are not excluded — subtract them manually if your calculation needs to.
