About this tool

Find a future or past date. Add or take away years, months, weeks and days from any date to work out a due date, a deadline, a 90-day period or a warranty end. Month ends are handled sensibly: adding one month to 31 January gives the last day of February.

When to use it

Find the date that is a number of days, weeks, months or years from a date, for due dates, notice periods and warranties.

Tips

Adding months uses calendar months, so 31 January plus one month is the end of February.
