## Limitations

You need an employer-selected benefit day or non-national schedule. Skip Saturday/Sunday and exact national statutory public holidays; do not add automatic substitute days. All values are computed from the formula above; no measurement or live data is involved.

## FAQ

**Are weekend public holidays moved to Monday?**

No automatic next-working-day closure is inferred; the WRC describes employer benefit options instead.
