DeadCal is a free online calculator that computes California civil court deadlines by counting court days or calendar days from a user-supplied date, with dedicated tools for specific filing scenarios.
Court and Calendar Day Counting
The core calculator allows a user to select a start date, choose between court days or calendar days, and count either forward or backward from that date. Court-day counts exclude weekends and configured statewide judicial holidays, while calendar-day counts include every date and apply landing-date adjustments under Code of Civil Procedure §§ 12, 12a, and 12c.
Rule-Specific Deadline Calculators
Separate calculators apply the base period, service extensions, and related dates for particular filing types: a noticed motion deadline calculator under CCP § 1005, a summary judgment motion deadline calculator, and a summons response deadline calculator.
Calculation Transparency
Results display the full sequence of dates considered, identify which days were skipped as weekends or holidays, and cite the governing statutory sections so users can cross-check the output against the underlying rule.
Built-In Holiday Data
Statewide California judicial holidays are built into the tool, with a displayed verification date indicating when the underlying rules and holiday calendar were last reviewed.
Educational Guides
The site includes plain-language guides on topics such as how to count California court days, motion deadlines under CCP § 1005, summary judgment deadlines, and how to respond to a summons.
DeadCal describes itself as an independent informational project rather than an official court service, and states that results should be verified against the governing statute, local court rules, and current holiday calendar before being relied upon.
