The WORKDAY function
A delivery date 10 working days out, not counting weekends or holidays.
Syntax
=WORKDAY(start_date, days, [holidays])
In a French Excel: =SERIE.JOUR.OUVRE(date_départ; nb_jours; [jours_fériés]).
Arguments
- start_date: the starting date, not counted.
- days: the working days to add; negative to go back.
- holidays: a range of dates to skip.
An example
=WORKDAY(A2,10,Holidays!$A$2:$A$12)
The date 10 working days after A2, holidays excluded.
Pitfalls
- Excel knows no public holiday: you have to list them.
- Another weekend (Friday and Saturday): WORKDAY.INTL.
