## Limitations

The remaining national, autonomous-community, Ceuta/Melilla and up to two municipal local holidays require a jurisdiction-specific calendar. 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

**Does this answer every Spanish region and municipality?**

No. It is the nationwide non-substitutable subset only; autonomous-community, Ceuta/Melilla and local holidays require a jurisdiction-specific official calendar.
