Singapore Working Day Calculator Features & Tools

Working & Calendar Day Modes

Switch between working-day and calendar-day counting, control direction, and include or exclude boundary dates to match contract wording.

Chain up to six deadline periods so finance, due diligence, completion, and notice stages stay in sync.

Apply the ROC 2021 day-counting rules: timelines of six days or fewer use working days, longer timelines use calendar days, and final dates roll forward if they land on a non-court day.

Calculate notice periods in calendar days, including weekends and public holidays, with clear start/end inclusion controls.

All 11 gazetted public holidays are included, and Sunday holidays roll to Monday automatically under the Holidays Act.

Uses the standard Mon-Fri business day definition (excluding Saturdays, Sundays, and public holidays) applied in conveyancing and banking contracts.

Security of Payment Act mode counts every day except gazetted public holidays, so weekends are included in adjudication timelines.

Visualize the result through a colour-coded timeline showing working days, weekends, and public holidays.
