California civil litigation deadline calculator.
Two modes, one tool. Compute response deadlines forward from a service date, or motion-calendar deadlines (moving papers, opposition, reply) backward from a hearing date — with court holidays, weekend roll-forwards, and the CCP citation behind every step.
Document received
Defendant's responsive pleading after being served with a summons + complaint.
For mail service, this is the date the document was deposited in the mail (the proof of service date), not the date you received it.
Service method
Extension: None
CCP § 415.10 — no extension
Process server hands the document to you directly.
Pick the document, the service method, and the service date.
Results appear here with the step-by-step computation and CCP citations.
Reference math, not legal advice. The calculator implements statewide California Code of Civil Procedure rules. Local court rules can adjust deadlines (and individual judges’ standing orders sometimes do too). Any stipulation between the parties or order shortening / extending time governs over the defaults shown here. When a deadline actually drives a decision, confirm with Think Legal, P.C. or verify on the court’s website.

Missed deadlines are usually fatal in California civil litigation. Most matters can be scoped in a thirty-minute conversation.
