What does the "include end date" option do?

If unchecked, for example Jan 1 to Jan 5 is calculated as 4 days (just the gap between them); if checked, both the start and end day are counted, giving 5 days.

What holidays does the "exclude official holidays" option cover?

This option covers official and religious public holidays in Turkey; when checked, these dates are automatically subtracted from the total day count.

Why can I manually exclude specific dates?

For example, if you want to leave out annual vacation days or company-specific holidays from the calculation, you can add those dates manually and have them subtracted from the total.

What happens if the start date is after the end date?

The tool automatically sorts the two dates regardless of which one you entered first, and calculates the difference between them as a positive value.
