Deadline Engine
Mildenhall, Bury St. Edmunds, England, UK
What it is
Deadline Engine calculates court and procedural deadlines and shows the governing citation with the steps used to reach a result. Its catalog lists 4,871 deadline rules across 20 jurisdictions. Calculations use deterministic rule logic rather than AI and account for deemed service, applicable clear-day rules, business-day adjustments, official bank holidays, and court office closures. Users can export matters as CSV or JSON, with PDF and calendar exports available per matter. Professional adds individual matters that retain histories of eligible server-recomputed calculations, calendar feeds, and downloadable ICS files. The free calculator needs no account. An Evidence Record costs $19.99, paid once and provides a permanent PDF for one eligible server-recomputed calculation. Professional costs $29.99 a month or $299.99 a year. The web service is intended for individual legal professionals, including solicitors, barristers, paralegals, and compliance professionals. It provides procedural information, not legal advice, and does not determine jurisdiction, interpret evidence, read court orders, or decide whether a rule applies to a case. Users are instructed to verify dates against rules and case facts.
