## Limitations

The division is unknown or employer/sector replacement-day rules matter. Normalize endpoints, apply endpoint flags, and count the official division calendar over its weekly baseline. All values are computed from the formula above; no measurement or live data is involved.

## FAQ

**Does this count a private employee's rest day?**

No. It reports only the declared division baseline and official public-holiday table.
