Questions people ask
Why is my count one day different from another tool?
Some tools count the end date and some do not. Choose the inclusive option to match one that does.
What if the end date is before the start date?
The dates are swapped and the result is labelled, so you never get a negative answer.
How are months worked out?
As whole calendar months, then leftover days. Months differ in length, so use days when you need an exact span.
Does it account for leap years?
Yes. It counts real calendar days.
Can it remove public holidays?
No. Holidays differ by country and year. Subtract them by hand from the weekday count.
