Frequently Asked Questions
What does "include end date" mean?+
By default, the calculator counts the number of full days between the two dates (exclusive). Checking this option adds 1 extra day to count both the start and end date as part of the range (inclusive).
Can the end date be before the start date?+
No, the end date must be on or after the start date. Swap the dates if you need to measure backward in time.
