FAQ
Is the end date included?
The result is the exact number of days from the start date to the end date. Add one if you need to count both endpoints (for example, total days of a hotel stay).
How is the years/months/days breakdown found?
By calendar arithmetic from the start date, so it accounts for different month lengths and leap years. The total-days figure is the precise measure.
Does order matter?
No. If the "to" date is earlier than the "from" date, the difference is shown as a positive span.
