DeadlineBook: litigation deadlines without the sticky-note calendar

Missed deadlines are a leading source of legal malpractice claims. Full practice-management suites and jurisdiction rules engines exist for larger firms. Many solos and small litigation shops still track answers, discovery, and hearing briefs in shared spreadsheets that do not recompute when a service date moves.

DeadlineBook is a free, local-first multi-matter deadline register. Data stays in the browser.

What you get

• Multi-matter register: docket #, court, client, counsel
• Deadlines from trigger date ± offset (calendar or US federal business days)
• Fixed due override when the formula does not apply
• Overdue / due-today / ≤7d / ≤30d aging and critical flags
• Illustrative FRCP-style templates (you confirm the rule)
• CSV and print

Honest limits

Not a court-rules engine. It does not apply FRCP or local rules for you. Holiday support is US federal only. Always dual-calendar and verify.
