How does CalendarRules help reduce calendaring risk?
CalendarRules helps legal teams reduce calendaring risk by replacing manual deadline calculation with rules-based calendaring built and reviewed by legal professionals.
For many firms, CalendarRules supports dual-entry calendaring workflows, where deadlines can be reviewed, confirmed, and entered through established docketing processes. Firms maintain internal controls while reducing the time and effort required to calculate deadlines manually.
By automating deadline generation and supporting review-based workflows, legal teams save time, improve consistency, and reduce the risk of missed or miscalculated deadlines.

How does CalendarRules calculate a deadline?
Every CalendarRules deadline calculation is built around four interacting components: Trigger: The event that starts the calculation, such as a filing, hearing, deposition, or trial date. Events: The deadlines generated by that trigger, including the first day or last day to act and whether the calculation is counted in calendar or court days Holidays: Jurisdiction-specific dates that affect how days are counted and how deadlines move when they fall on a weekend or holiday. Service offsets: Additional time that may be added based on how documents were served, such as by mail, electronic service, or personal service.
The interaction between these components — especially the way holidays and service rules apply together — is where manual deadline calculations can become difficult. CalendarRules applies that logic through rules-based calendaring to help legal teams calculate deadlines more consistently.

How are CalendarRules jurisdictions built?
Each jurisdiction in CalendarRules is built as a layered combination of legal authorities, including: Base rules: Statewide or system-wide rules, such as the Federal Rules of Civil Procedure or a state code of civil procedure. Local rules: Rules adopted by a specific court that may supplement or modify the base rules. Specialty or judge-specific rules: Standing orders or rules tailored to particular case types, such as family, probate, or limited civil matters.
When a local rule modifies a base rule, the CalendarRules jurisdiction reflects the rule as it applies in that specific court. CalendarRules is designed to apply the relevant priority logic, allowing users to work from the rules that apply to the selected court and matter type.

How often are CalendarRules rules updated?
CalendarRules monitors court rule changes through automated tracking tools, direct court notifications, and manual review.
Rules are updated based on the effective dates of the final versions of the rules, and on a steady cadence that allows the CalendarRules team to follow its review protocols. Proposed amendments are tracked from publication through adoption. Standing orders are also monitored on an ongoing basis, since judges are not always required to publish them in advance.

Who builds and reviews CalendarRules rule sets?
CalendarRules rule sets are built and maintained by licensed attorneys and experienced paralegals with litigation and docketing backgrounds. Questions about rule content are handled by the same legal team that builds and maintains the rules.
