## Limitations

Provincial, municipal, employer, bank, exchange, school, sector and religion-specific schedules are not generalized; regional one-off holidays are not included in this nationwide default. 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

**Are religious dates universal closures?**

No. They are returned as scoped events but the default working-day status does not mark them as universal closures.

**Are provinces and employers covered?**

No. This is a nationwide 2026 package; provincial, local, employer and sector schedules require separate evidence.
