Employment Ordinance Notice Period

Scenario

An employee with 3 years of service resigns on 15 Sep 2025. Assume a post-probation continuous contract where the contract is silent on notice, so the Employment Ordinance minimum applies (commonly 1 month, subject to probation rules). Notice runs on calendar days (including weekends and public holidays). Calculate the last day of employment.

Notice Given: 15 Sep 2025

Notice Period: 1 calendar month

Last Day of Employment: 15 Oct 2025 (Wednesday)

In this example, one month runs to the corresponding date in the next month. Weekends and public holidays are included, so the count does not pause.

Confirm exact end-date mechanics against the contract wording and internal HR practice.

Why This Matters

•Ensures notice periods comply with Employment Ordinance minimums
•Prevents disputes about whether weekends and public holidays count
•Clarifies that employment can end on any day, including weekends
•Provides a precise last day of employment for payroll and HR
•Supports clear documentation in resignation or termination letters

High Court Short Filing Deadline

Scenario

You receive an order from the High Court requiring your client to file a reply within 5 days of service. The order was served at 4:30 PM on Tuesday, 6 January 2026. In this scenario, you first work out the deemed service date under the applicable service rule. For short periods, Saturdays, Sundays, and General Holidays are excluded. Use the calculator to count from that deemed service date and confirm the exact rule/order wording for your step.

Court Rules

Result Example

Service Time: 4:30 PM on 6 Jan 2026

Deemed Service Date: 7 Jan 2026 (used as the trigger date in this example)

Timeline: 5 working days (from 8 Jan 2026)

Deadline: 14 Jan 2026

In this example, the applicable service rule makes 7 Jan the deemed service date, so the 5-day period begins on 8 Jan.

Saturday and Sunday are excluded from the 5-day count. If the final day lands on a non-court day, the deadline may roll to the next eligible day under the applicable rule.

Tap to enlargeClick to enlarge

Why This Matters

•Automatically applies short-period rules
•Works from the deemed service date after you determine the correct trigger date
•Excludes Saturdays, Sundays, and General Holidays for periods of 7 days or less
•Rolls deadlines forward if the final day is a non-court day

High Court Pleading Deadline That Excludes August

Scenario

You are working on a High Court pleading step where RHC Order 3 rule 3 excludes the Summer Vacation. The triggering step occurs on 30 July 2026 and the applicable pleading deadline is 5 days after service. Because this is one of the narrow pleading situations where August is excluded, you turn on the August exclusion control instead of treating it as a baseline Hong Kong court rule.

Court Rules

Result Example

Trigger Date: 30 July 2026

Timeline: 5 days after service, with August excluded under RHC Order 3 rule 3

Deadline: 4 September 2026

Without the pleading control, a 5-day filing period from 30 July 2026 would finish on 6 August 2026. Turning on Exclude Summer Vacation (August)skips the entire month of August, so the count resumes on 1 September and finishes on Friday, 4 September 2026.

Why This Matters

•Shows when August is excluded for High Court pleading deadlines
•Keeps the August exclusion as an explicit user-selected rule control
•Makes it clear that the exclusion is not a baseline rule for every HK deadline
•Provides a concrete worked example for RHC Order 3 rule 3

ASP Execution Deadline (First-hand Sale)

Scenario

Your client enters into a Preliminary Agreement for Sale and Purchase (PASP) for a first-hand residential property on 28 January 2025. Under the Residential Properties (First-hand Sales) Ordinance (Cap. 621), the purchaser must execute the formal Agreement for Sale and Purchase (ASP) within 5 working days. Lunar New Year falls on 29–31 January — all General Holidays. Calculate the last day your client can sign the ASP.

Deadline

Result Example

PASP Signed: 28 Jan 2025 (Tuesday)

Lunar New Year Holidays: 29–31 Jan (3 General Holidays excluded)

Working Days 1–5: 3, 4, 5, 6, 7 Feb

ASP Deadline: 7 February 2025 (Friday)

Without the holiday adjustment, a naive count would suggest 4 February — but the three LNY General Holidays push the deadline to 7 February.

Missing this deadline forfeits the preliminary deposit and terminates the PASP under Cap. 621.

Why This Matters

•Ensures compliance with Cap. 621 (Residential Properties (First-hand Sales) Ordinance)
•Automatically excludes weekends and all Hong Kong General Holidays
•Helps identify holiday-cluster compression risk before signing appointments are booked
•Prevents accidental forfeiture of the preliminary deposit through a missed deadline
•Provides a defensible, auditable deadline for both parties' solicitors

Substantial Shareholder Disclosure (SFO Part XV)

Scenario

Your fund acquires additional shares in a Hong Kong-listed company on Thursday 2 April 2026, pushing its holding above the 5% threshold. Under Part XV of the Securities and Futures Ordinance (Cap. 571), notice is generally required within 3 business days of awareness and is given to both SEHK and the listed corporation concerned. The Easter/Ching Ming holiday cluster follows immediately after. Calculate the disclosure deadline.

Deadline

Result Example

Awareness Date: 2 Apr 2026 (Thursday)

Non-working days: 3 Apr (Good Friday), 4 Apr (day following Good Friday), 5 Apr (Sunday), 6 Apr (day following Ching Ming), 7 Apr (day following Easter Monday)

Business Days 1–3: 8, 9, 10 Apr

Disclosure Deadline: 10 April 2026 (Friday)

A naive 3-day count from Thursday would suggest Monday 7 April — but the Easter and Ching Ming cluster eliminates 5 consecutive calendar days, pushing the deadline to 10 April (8 calendar days later).

Late or missed Part XV disclosure can be a criminal offence, and fines and/or imprisonment may apply.

Why This Matters

•Ensures compliance with the 3-business-day deadline under SFO Part XV
•Automatically excludes weekends and all Hong Kong General Holidays
•Accounts for holiday clusters (Lunar New Year, Easter, Ching Ming) that compress filing windows
•Helps reduce late-filing risk in high-pressure compliance windows
•Provides a clear, auditable deadline for compliance records

SFBC Interim Payment Certificate Response

Scenario

The architect issues an interim payment certificate on 29 September 2025 under a standard-form construction contract. The contractor must issue a payment response within the period stated in the contract (14 working days in this example). In this scenario, working days exclude Sundays and General Holidays. National Day (1 October) and Mid-Autumn Festival (7 October) both fall within this period. Calculate the response deadline.

Result Example

Certificate Issued: 29 Sep 2025 (Monday)

General Holidays in Window: 1 Oct (National Day), 7 Oct (Mid-Autumn Festival)

Working Days 1–14: 30 Sep, 2-4 Oct, 6 Oct, 8-11 Oct, 13-17 Oct

Payment Response Deadline: 17 October 2025 (Friday)

A naive 14-day calendar count would suggest 13 October — but excluding Sundays, National Day, and the Mid-Autumn Festival pushes the deadline to 17 October.

Missing the payment response deadline can trigger adjudication or arbitration proceedings under the contract, and may affect the contractor's right to dispute the certified amount.
