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.
