About Working Day Calculator UK
Our Mission
UK working day calculations shift across three jurisdictions, varying bank holiday substitutions, and court rules that treat "clear days" differently from calendar days. Generic calculators rarely keep pace with CPR or SCTS guidance.
Legal, conveyancing, procurement, and project teams waste time counting dates manually, double-checking court closures, and reconciling deadline chains. Our mission is to eliminate that friction with a tool designed for the UK reality.
Working Day Calculator UK provides defensible, exportable timelines backed by official sources and transparent methodology.
What We Do
The calculator covers every aspect of UK working day computation:
- Jurisdictional Bank Holidays: Accurate holiday calendars for England & Wales, Scotland, and Northern Ireland.
- Substitute Day Rules: Automatic handling of holiday substitutions when dates fall on weekends.
- Court Rules Mode: Clear-day calculations aligned with CPR Part 2, Scottish civilis computatio, and Northern Ireland court rules.
- 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.
