## Limitations

Mandatory nationwide list only. Municipal, autonomous-region, collective-agreement, employer and locally substituted holiday 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

**Does this include Carnival Tuesday or Lisbon municipal day?**

No. Portuguese law treats Carnival Tuesday and the municipal holiday as optional through collective regulation or contract; this package includes only the mandatory nationwide list.
