## Limitations

Nationwide statutory holiday list only. Saturday substitute dates, individual work schedules, employer, sector, school, bank and local 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

**Is a Saturday substitute date returned?**

No. Polish labour guidance makes the additional day off dependent on the employee's five-day schedule, employer and settlement period; this package preserves the statutory holiday and does not invent a substitute date.
