## Limitations

Nationwide statutory holiday list only. Saturday substitute dates, individual work schedules, employer, sector, school, bank and local schedules are not inferred. Apply the pinned authority event table over the declared weekday baseline; do not infer uncovered employer or regional schedules. 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.
