Pick two dates to find exactly how much time separates them — in days, weeks, months, and years.
The total-days figure is a straight count of calendar days between the two dates. The years/months/days breakdown counts full calendar units the way you would by hand — for example, from January 15 to March 20 is 2 months and 5 days, not just a raw day count divided by 30. If the end date is earlier than the start date, swap them and the result will describe the reversed order.
