Cal. Code Civ. Proc. 12, 12a, 12b, 10; Cal. Rules of Court, rule 1.10
CCP 12: "The time in which any act provided by law is to be done is computed by excluding the first day, and including the last, unless the last day is a holiday, and then it is also excluded." CCP 12a(a): "If the last day for the performance of any act provided or required by law to be performed within a specified period of time is a holiday, then that period is hereby extended to and including the next day that is not a holiday. For purposes of this section, “holiday” means all day on Saturdays, all holidays specified in Section 135 and, to the extent provided in Section 12b, all days that by terms of Section 12b are required to be considered as holidays." CCP 12b: "If any city, county, state, or public office, other than a branch office, is closed for the whole of any day, insofar as the business of that office is concerned, that day shall be considered as a holiday for the purposes of computing time under Sections 12 and 12a." CCP 10: "Holidays within the meaning of this code are every Sunday and any other days that are specified or provided for as judicial holidays in Section 135."

  • CCP 1013 mail extensions do NOT apply; the 415.20/415.30/415.40/6064 completion rules govern. Count 30 calendar days from completion of service, roll forward under CCP 12a. CCP 412.20 amended eff. 2026-01-01 (AB 863) without changing the 30 days. CRC 3.110(d) allows one stipulated 15-day extension without court order. A motion to strike filed without a demurrer extends time to answer (CCP 435(c)). Unlawful detainer uses CCP 1167 instead (see unlawful_detainer_response). Publication add_days is a computation from Gov. Code 6064 text; confirm the court's order for any longer publication period (CCP 415.50(b)).
  • If the clerk's office is closed or inaccessible on the last day (weather, emergency or local closure orders), the deadline may be extended. Check local orders.

This calculator applies the cited rules to the dates you enter. It is not legal advice. Court orders, local rules, and case-specific facts can change a deadline; verify before relying on it. Rule set pending attorney review.

How it works

1

Pick the court and case type

Statewide rules plus the local rules for your county, Court of Appeal district, or federal court. Civil, family, probate, evictions, small claims, government claims, criminal, juvenile and appeals.

2

Enter the dates you know

Summons served, trial date, hearing dates, judgment. Each date adds every deadline that runs from it, adjusted for court holidays, court days and the method of service.

3

Subscribe once, stay current

One click puts the case on your Outlook, Google or Apple calendar. Continue the trial and the right deadlines move while discovery cutoffs stay on the original date, as the Code requires.

Built to be checked, not trusted blindly

The math and the rule, every time

Each result lists the counting steps, the holidays it skipped, and the verbatim rule text with a link to the official source. You can verify any date in seconds.

Independently reviewed

Every rule set is researched from official text, then re-checked line by line by a separate reviewer who hand-computes test cases. The calculator must reproduce every case before it ships.

Watched every day

We re-read 2,354 official sources on a rolling schedule and flag any amended or moved rule text. Changes are logged publicly in the rules changelog.

Honest about gray areas

Where the law is unsettled (an observed holiday, a disputed extension), the calculator shows the safer date and tells you why. Not legal advice: court orders and case facts can change a deadline.

Questions

Can I rely on these dates?

Use them the way you would use a careful colleague's calculation: check the steps and the rule text shown with every result. Court orders, stipulations and case-specific facts can change a deadline, and where the law is unsettled we show the safer date and explain why.

What happens when a rule changes?

Saved cases are recomputed from the current rules every time you open them or your calendar syncs. We monitor the official sources daily and log every change in the public changelog.

How does the calendar sync work?

Each case gets a private subscription link. Add it to Outlook, Google Calendar or Apple Calendar once; your calendar re-checks it every few hours, so new or moved deadlines appear without you doing anything.

What does continuing the trial do?

Deadlines that run from the current trial date (summary judgment hearing, for example) move. Deadlines the law ties to the initial trial date (discovery and expert cutoffs under CCP 2024.020) stay put, and each one is labeled.

Is my case information private?

Cases are visible only to your account. The calendar link is private to you; anyone with the link can see that case's deadlines, so share it only with your team.

Can my AI assistant use this?

Yes. Add the 1Court MCP connector to Claude or another MCP-enabled assistant and ask for a deadline; it returns the date, the steps and the citations.
