## Limitations

Local-government special holidays, employer schedules and 2027 Eid dates pending a separate proclamation 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 every listed date a day off?**

No. The package preserves the proclamation's special working day classification; local and employer calendars are outside scope.
