## Limitations

You do not know the state/territory, or you need a local council, regional, employer, exchange or industry calendar. Resolve the required division, apply official full-day dates, and surface limited/part-day events separately without treating them as full-day closure. All values are computed from the formula above; no measurement or live data is involved.

## FAQ

**Can I omit the division?**

No. Australian public holidays differ by state and territory.

**Are regional holidays included?**

They are returned as limited_or_part_day_events when present, but do not close the whole division by default.
