## Limitations

This package is the Hong Kong general/public-holiday calendar. Statutory employee holidays, employer rest days, school calendars, bank/exchange closures and private-sector arrangements are not inferred. 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

**Does this represent every Hong Kong employee's statutory holidays?**

No. It is the government/general-holiday calendar. Hong Kong Labour Department statutory holidays and employer rest-day compensation follow separate Employment Ordinance rules.

**Is Saturday always a weekend in this package?**

No. The general-holiday calendar explicitly lists certain Saturdays as holidays; ordinary Saturdays are not silently treated as Sundays.
