What CalendarRules does

CalendarRules is a cloud-based court rules automation platform that converts U.S. and Canadian court rules into automated deadline calculations for legal professionals. The company's proprietary software covers approximately 2,000 rule sets across 2,500+ federal, state, bankruptcy, appellate, local, judges, and agency jurisdictions, using a layered architecture that combines base rules (e.g., Federal Rules of Civil Procedure or state codes), local rules, and specialty or judge-specific rules (standing orders, family, probate). Rule updates propagate to all subscribers in as little as 15 seconds via single-button push, and the company adds approximately 100 new jurisdictions per year. Native integrations deliver deadlines directly into Microsoft Outlook (CR for Outlook / CRO) and Google Calendar (CR for Google / CRG), with no local servers or installation fees.

CalendarRules serves 2,600+ legal organizations and government agencies, including one in four AmLaw-ranked firms, with named customers such as Akin Gump Strauss Hauer & Feld, Baker McKenzie, Hogan Lovells, Bryan Cave Leighton Paisner (BCLP), Katten Muchin Rosenman, and WilmerHale. Customers use the platform to generate approximately 30 million deadlines per year, and CalendarRules reports a customer retention rate of nearly 100%, stating it has never lost a customer because of dissatisfaction with rules content.

Revenue is generated through subscription licensing priced by quote based on firm size and number of selected jurisdictions, with mid-subscription court additions prorated, plus a secondary OEM/licensing stream where the rules engine is embedded in 20+ third-party case management and docketing systems. Distribution spans direct sales with personalized demos and unlimited free trials, a self-serve tier via mobile apps (Date Calculator, Docket Calculator, Docket Research) and DocketTools web tools, and indirect channel partnerships with integrators including Clio, BEC Legal, CaseFlow, CourtAlert, DocketAlarm, JuraLaw, Litify, SmartAdvocate, and Tabs3. CalendarRules was founded in October 2007 as a spin-out from OpenText and was acquired by Clio in June 2021, continuing to operate under its own brand while leveraging parent-company distribution.
