Date Difference Calculator
Count the days, weeks, months and working days between two dates.
To find the difference between two dates, enter both and the total is given in days, weeks, months and years, along with a separate count of working days. Enabling "include the end date" counts both endpoints, which is how contracts and hire periods are usually measured.
