Date Calculator
Days between two dates, or a date plus/minus any number of days.
About this tool
Count the days between two dates, or add and subtract days from a date - with weeks, months and years equivalents. Useful for deadlines, notice periods and project planning.
Does it count both end dates?
It counts the difference between the dates, so Monday to Friday is 4 days. Add 1 if your use case includes both ends.
Does it handle leap years?
Yes - calculations use the calendar itself, so February 29 is handled correctly.
