Date Add/Subtract

What is Date Add/Subtract?

A date add/subtract calculator lets you find a future or past date by adding or subtracting days, weeks, months, or years from any starting date. Use it for deadlines, due dates, expiration dates, or event planning.

How to use

1. Select a starting date from the date picker or use today's date as default.
2. Enter the number of days, weeks, months, or years to add or subtract.
3. The result date is calculated instantly, showing the day of the week and how far it is from today.
