What is the days from today calculator?

Use this calculator to find a date a certain number of days, weeks, months, or years after or before today. You can also choose a different base date when you need to calculate from a contract date, event date, invoice date, reservation date, or deadline.

The result appears immediately and can be copied in US long, UK long, ISO, or summary format.

Add or subtract days, weeks, months, or years

Choose After to move forward from the base date, or Before to move backward. The preset buttons cover common offsets such as 30, 60, 90, 120, 180, and 365 days, plus calendar-month options like 3 months and 6 months.

For exact day counts, use the day presets. For calendar periods, use months or years.

How month-end dates are handled

Calendar month and year offsets use month-end rounding. For example, adding 1 month to January 31 returns the last valid day in February.

This is different from adding a fixed number of days. For example, 180 days and 6 months can produce different dates, and 365 days is not always the same as adding 1 calendar year.

Common use cases

  • Check trial periods, return windows, or monthly deadlines.
  • Calculate reminder dates for school, exams, appointments, or events.
  • Work out a submission or review date without opening a spreadsheet.
  • Copy a date into email, notes, task managers, or project plans.
