Frequently asked
What happens if the end date is before the start date?
The calculator still works. It shows the absolute difference between the two dates and flags that the end date came first.
Are the start and end dates both counted?
The total is the number of days between the two dates (end minus start), so choosing the same date for both gives zero.
How is the years/months/days breakdown different from total days?
Total days is a straight count. The years/months/days breakdown is calendar-aware. It accounts for different month lengths and leap years the way you'd count by hand on a calendar.
