Overview
Deadline Engine is a web tool for calculating court and procedural deadlines. It displays the governing citation and the steps behind each calculation, drawing on a catalog that the homepage says contains 4,871 rules across 20 jurisdictions. Its deterministic rule logic accounts for deemed service, applicable clear-day rules, business-day adjustments, official bank holidays and court office closures; it does not use AI to calculate deadlines. The free calculator requires no account. Users can export matters as CSV or JSON, with PDF and calendar exports available per matter. Professional keeps histories of eligible server-recomputed calculations on individual matters and adds calendar feeds and downloadable ICS files. The service does not determine jurisdiction, interpret evidence, read court orders or decide whether a rule applies to a case. Deadline Engine describes its output as procedural information, not legal advice, and says dates should be checked against rules and case facts. It is developed for individual legal professionals, including solicitors, barristers, paralegals and compliance professionals.
Who it is for
It suits legal professionals who need deadline calculations with citations and calculation steps, or matter records and calendar feeds through Professional. Users must assess whether a rule applies and verify dates against the rules and case facts themselves.
