How to use it

How to use add or subtract date

Move a calendar date forward or backward by days, weeks, months, or years without manually counting calendar boundaries.

Add 45 days to an invoice date or subtract three months from a renewal date.

  1. Enter or paste the values you want to work with.
  2. Review the result and any validation message.
  3. Copy or download the result when the tool provides that action.

How it works

Calendar units are applied to the chosen date, and invalid month-end or leap-day results are clamped to the last valid day.
