## Limitations

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. Normalize endpoints and count exact authority events over the declared weekday baseline. All values are computed from the formula above; no measurement or live data is involved.

## 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.
