## Limitations

The division is unknown, or you need an employer, bank, exchange, school or inferred replacement-day calendar. Require the division, apply the pinned official table and division weekend baseline, and preserve replacement-day uncertainty. All values are computed from the formula above; no measurement or live data is involved.

## FAQ

**Can I omit division?**

No. Malaysia's federal-territory/state calendars differ.

**Does a weekend holiday automatically create a replacement day?**

No. This package does not infer employer or legal replacement dates.
