How it counts
By default the start date is counted and the end date is not – the same way you would count nights in a hotel stay. Choose “Include end date” to count both, which is common for notice periods and leave.
Weekdays are Monday to Friday. UK bank holidays vary by nation and year, so subtract any that fall in your range.
