Days between dates

Ready

Calculate the difference between two dates in days, months and years. Working days and weekends are counted separately. Dates are processed in the browser and never stored.

All tools are free to use. File size and processing limits may vary by tool.

How to use

Pick the start and end dates; total days, months and years plus working days and weekend days appear. Useful for project planning and contract durations. Holidays are not excluded, only weekends.

How are files processed?

Browser tools keep files on your device. Advanced document tools upload files for temporary server processing; the tool shows this before upload. Web lookups send queries to the server and public lookup services.
