Covers Hong Kong's public holidays. Easter-based holidays are computed for any year. Lunar-based holidays (Chinese New Year, Ching Ming, Buddha's Birthday, Tuen Ng, Chung Yeung) are from approximate annual override tables — verify with the HKSAR Government.
Formula
Working Days = Weekdays − General holidays falling on weekdays
Count all Monday–Friday days in the range, then subtract Hong Kong's statutory general holidays that fall on those weekdays. Hong Kong observes 16 general holidays per year — significantly more than most comparable financial centres. Several are lunar-based and shift annually.
Worked Example
Scenario: A Hong Kong trading company gives a supplier a 10 working day window starting Wednesday 29 January 2025.
Chinese New Year runs from 29–31 January — three consecutive public holidays covering Wednesday, Thursday, and Friday.
10 working days + 3 CNY holidays = 13 weekdays forward
Result: deadline falls on 14 February 2025
Chinese New Year is one of the most disruptive periods for Hong Kong business operations. Build significant buffer into any deadlines covering late January or early February.
Common Mistakes
- Chinese New Year is three days, not one. Hong Kong observes the first three days of the Lunar New Year as public holidays. This contrasts with Singapore (two days) and mainland China (varies). Contracts covering late January or early February should account for three consecutive holiday days.
- Lunar holiday dates shift each year. Ching Ming Festival, Buddha's Birthday, Tuen Ng Festival, and Chung Yeung Festival are all based on the Chinese lunar calendar. Their Gregorian dates change every year. Never copy dates from a previous year's calendar without verification.
- Confusing General Holidays with Bank Holidays. Hong Kong distinguishes between General Holidays (which apply broadly) and Bank Holidays (a larger set under the Banking Ordinance). If you work with Hong Kong banks, add the full Banking Ordinance holiday list for accurate payment timeline calculations.
