Legal Deadline Calculator, Built Into the Case File
A legal deadline calculator turns a trigger date (service, judgment, filing) plus a rule's day count into the date a response is due, rolling weekend landings forward to the next court day. Use the free calculator below, no signup required.
Then see how Caseagent does the same job automatically, for every date in every matter. Caseagent is in early access; the calculator on this page is educational and is not legal advice.
A court deadline calculator you can use right now
Six common rule presets, plain calendar-day math, and an honest label on every result. If the computed date lands on a Saturday or Sunday, the calculator rolls it forward to Monday and says so.
This is the manual version of what the agent does continuously. When Caseagent reads a filing, it runs this computation for every date it finds and puts the result on the matter timeline. See how the agent loop works.

More than a court date calculator: the agent reads the filings
A court date calculator is only as good as the person who remembers to open it. Caseagent removes that person from the failure path: the agent finds the dates, computes the deadlines, and keeps reminding until a human confirms.
Date extraction runs on every document the AI paralegal reads into the matter: pleadings, orders, correspondence, proofs of service. You can watch the same reading step in the live demo.
A litigation deadline calculator wired into the matter timeline
Here is what one computed deadline looks like on a Caseagent matter timeline: a 21-day federal answer clock, from service to due date, with the escalation path visible. Illustration of planned product behavior.
Every computed deadline carries its rule source and trigger document, and an attorney can adjust any date. The agent calculates; the lawyer decides.
Missed deadlines are the most preventable malpractice claim
Calendaring and deadline errors are consistently cited in ABA-published malpractice studies as a leading, and the most preventable, source of claims against lawyers.
The failure mode
Deadline errors rarely come from bad lawyering. They come from a date that was never entered, a rule misread under pressure, or a calendar nobody was watching that week.
The usual fix
Double-entry calendaring and a paralegal who owns the docket. It works, and it costs staff time on every single filing, forever.
The agent's fix
Extraction and computation happen the moment a document enters the file, and escalation never gets tired. A human still confirms every deadline; the human just never has to find it first.
Deadline tracking is one part of the same agent that drafts your documents and keeps client communication organized. It also powers the status updates in legal intake software and client communication, and the planned tiers on the pricing page all include it. Caseagent is a tool for lawyers, not legal advice, and an attorney reviews everything it produces. Not sure how a specific rule counts days?
