About this calculator
Going backwards in the calendar is just as common as going forward — finding the date 30 days ago, the date 5 years before a deadline, the start of a 90-day window. This calculator subtracts the amount you specify from a base date, applying the same month-clamp rule as date-add.
Frequently asked
Yes — under the hood it is the same calculation. The separate calculator exists because thinking "subtract 30 days from today" is more natural than "add −30 days".
