Calculate difference between dates
You can calculate the exact duration (years, months, weeks, days) between two dates, or add/subtract a specific number of days, weeks, months, or years to a start date to find the future or past date.
Yes, our date calculator automatically handles leap years (which add an extra day in February every four years) and tracks the differing lengths of months (28, 30, or 31 days) for perfect calculations.
To add or subtract days, select the 'Add/Subtract' tab, enter your starting date, choose the direction (add or subtract), input the number of days, weeks, months, or years, and the tool will instantly output the target calendar date.
