Frequently asked questions
Does the calculator count both the start and end date?+
By default it counts the number of nights between the dates. Turn on "include end day" to count both endpoints, which adds one day to the total.
Can it work out a date in the past?+
Yes. You can set the end date earlier than the start date and it will show the absolute difference between them.
