Add Austria Working Days

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

When to use

You need a deterministic Austria working-day offset.

Do not use when: Nationwide statutory holiday list only. Werktag is not uniform across Austrian legal domains; Saturday treatment, provincial patron days, school, bank, employer and sector schedules are not inferred.

FAQ

Does this define every Austrian Werktag?

No. It identifies nationwide statutory public holidays. Austrian government guidance states that Werktag is not defined uniformly across all legal domains, so callers needing a legal deadline or sector schedule must select the applicable rule separately.
