📆 Date Calculator

What date is 90 days from today? Or 6 months before a deadline? Pick a start date, add or subtract any mix of days, weeks, months and years, and get the exact resulting date.

How to use the Date Calculator

  1. Select the start date.
  2. Choose Add or Subtract, and fill in any of the amounts — days, weeks, months, years.
  3. Press Calculate — the resulting date appears with its weekday.
Example: Adding 30 days to 15 January 2026 gives Saturday, 14 February 2026.

Frequently Asked Questions

In what order are the amounts applied?

Years first, then months, then weeks and days — the natural calendar order, so month-end dates behave the way people expect in everyday planning.

Can I subtract a date range?

Yes — choose Subtract and enter the amounts to go backwards from the start date.

How is this different from Days Between Dates?

That tool measures the gap between two dates. This one starts from one date and moves it forward or backward.
