About this tool
Adds or subtracts days, business days, weeks, months or years from a date and returns the resulting date with its weekday. Month arithmetic keeps the end of the month, so 31 January plus one month gives 28 or 29 February.
How to use it
- Pick the start date.
- Choose add or subtract, the amount and the unit.
- Read the resulting date and weekday.
