Add Norway Working Days

Adds or subtracts Norway authority-scope working days in exact coverage.

When to use

You need a deterministic Norway working-day offset.

Do not use when: Nationwide statutory full-day list only. Christmas Eve, Easter Eve, Whit Eve, New Year's Eve, collective-agreement, employer, sector, school, bank and local closures are not inferred. Norwegian annual-leave law treats Saturdays separately from Sundays and public holidays; this package uses the declared Monday-Friday business baseline.
