Overview

Find the exact time between two dates — as a calendar-aware breakdown (years, months, days) and as raw totals (days, weeks, hours).

How it works

The calculator counts full calendar years, then full calendar months within the remaining span, then the leftover days — so "1 year, 2 months, 5 days" means exactly that, accounting for different month lengths and leap years. It also shows the plain total number of days between the two dates, which is what you want for things like counting a rental period or a project duration.

How to use this calculator

  1. Pick a start date and an end date.
  2. The breakdown and totals update instantly.
  3. Order doesn't matter — pick the dates in either order and the calculator will show the correct span.
