How the counting works
Midnights, not dates; Monday to Friday, not holidays; and calendar months that don't all have 30 days.
Working days skip weekends
Working days are Monday to Friday. Public holidays differ by country and region, so subtract them yourself if one falls in the period.
Every result has its week
The result also names the ISO week the date falls in, the number most calendars and planning tools use.
