About Working Day Calculator Singapore
Our Mission
Singapore deadlines combine working-day rules, calendar-day notice periods, and court-specific thresholds under the Rules of Court 2021. Public holidays and court recess periods add another layer of complexity.
Legal, HR, conveyancing, and project teams waste time counting days manually and cross-checking holiday observance. Our mission is to remove that uncertainty with a calculator designed for Singapore's working day rules.
Working Day Calculator Singapore delivers defensible, exportable timelines backed by official sources and a transparent methodology.
What We Do
The calculator covers every part of Singapore working day computation:
- Public Holiday Calendars: Accurate statutory holiday dates and substitute day handling.
- Court Rules Mode: ROC 2021 calculations for short working-day periods and longer calendar-day thresholds.
- Court Recess Periods: June and December recess periods reflected in deadline calculations.
- Sequential Deadline Chains: Multi-stage projects stay in sync with up to 6 consecutive periods.
- Exportable Audit Trails: PDF and ICS exports for defensible documentation and calendar integration.
Every calculation shows its work: start date, end date, inclusions, exclusions, and a visual timeline with excluded days clearly marked.
