Add or subtract court days from a date, skipping weekends and California judicial holidays. Use this for any period a statute states in court days rather than calendar days, such as the nine and five court day opposition and reply periods under Code of Civil Procedure section 1005(b). Counting court days by hand is where most deadline errors come from.
The date to count from. The starting day itself is not counted.
How many court days to move. Negative counts backward.

}Compute the California Rule of Court 4.111 briefing chain for a criminal pretrial motion: service of the moving papers, the proof of service, opposition, reply, and the hearing. Also gives the outside deadline for motions that run from a triggering event, such as the Penal Code section 995 motion and the section 1510 tracks. There is no service-method extension in criminal motions; rule 4.111 does not provide one.
| Argument | Type | Description |

| role | string | Whether you are bringing the motion or responding. |
| motion* | string | Which motion. pc-995 = Motion to set aside the information or indictment (§ 995); pc-1510-outside-deadline = Deadline to preserve pretrial writ review of a § 995 or § 1538.5 denial, felony (§ 1510); pc-1510-outside-deadline-misdemeanor = Deadline to preserve pretrial writ review of a § 995 or § 1538.5 denial, misdemeanor (§ 1510); pc-1424 = Motion to recuse the district attorney (§ 1424); pc-1538-5-prelim = Motion to suppress at the preliminary hearing (§ 1538.5(f)); pc-1538-5-special-hearing = Special suppression hearing in superior court (§ 1538.5(i)); pitchess-criminal = Pitchess motion, criminal (Evid. Code § 1043(a)(2)); pc-1054-5-compel = Motion to compel criminal discovery (§ 1054.5(b)); pc-1054-7-disclosure = Reciprocal discovery disclosure deadline (§ 1054.7); pc-1050-continuance = Motion to continue (§ 1050(b)); pc-1049-prepare = Time to prepare for trial (§ 1049); crc-4-110-information = Information after a holding order (CRC 4.110) |
| hearing_date* | string | The hearing date. For the section 1538.5(i) special hearing, this is instead the date notice was given to the People, because that clock runs forward. |
Compute when responses to California written discovery are due: interrogatories, requests for production, or requests for admission. Takes the date the discovery was served and how it was served, applies the section 1013 extension for that method (or the section 1010.6 extension for electronic service made before January 1, 2027, which AB 540 removes for service on or after that date), and rolls the result off weekends and judicial holidays under section 12a.

}Compute the California Code of Civil Procedure section 1005 briefing chain for a noticed civil motion: the last day to file and serve the moving papers, the opposition deadline, the reply deadline, and, for motions that must be brought within a period after a triggering event (demurrer, motion to strike, anti-SLAPP, motion to quash, motion to compel further, reconsideration, new trial, JNOV), the outside deadline to bring the motion at all. New trial and JNOV are the exception to the section 1005 chain: they are briefed under section 659a, counted forward (brief 10 days after the notice of intention is filed, opposition 10 days after the brief is served, reply 5 days after that), with the section 660(c) last day for the court to rule. Returns each date with the statute it rests on and whether it was moved off a weekend or judicial holiday: forward under section 12a for a period that runs forward, or back to the preceding court day for a count backward from the hearing, which is this site's stated convention. Use this instead of computing California motion deadlines yourself.
| Argument | Type | Description |
|---|---|---|
| role | string | Whether you are bringing the motion (moving) or responding to it (responding). |
| motion* | string | Which motion. compel-further = Motion to compel further responses; compel-initial = Motion to compel initial responses; protective-order = Motion for protective order; demurrer = Demurrer; motion-to-strike = Motion to strike; judgment-on-pleadings = Motion for judgment on the pleadings; quash-service = Motion to quash service of summons; anti-slapp = Anti-SLAPP special motion to strike; msj = Motion for summary judgment / adjudication; reconsideration = Motion for reconsideration; new-trial = Motion for new trial; jnov = Motion for judgment notwithstanding the verdict; preference = Motion for trial preference; reopen-discovery = Motion to reopen discovery; compel-arbitration = Motion to compel arbitration; ex-parte = Ex parte application |
Compute when a response to a California complaint is due. Handles the four service methods separately, because each completes service on a different day, and applies the extensions a defendant may claim: the section 430.41 meet-and-confer declaration, the rule 3.110(d) stipulated 15 days, and a court-ordered extension. Unlawful detainer runs on section 1167 instead and is handled as its own case type.
| Argument | Type | Description |
|---|---|---|
| case_type | string | Unlawful detainer runs on a different statute and a much shorter clock. |
| service_date* | string | The date on the proof of service. What it means depends on the method: for personal service the date of delivery, for substituted service the date of the substituted delivery, for notice and acknowledgment the date the defendant signed. |
| service_method* | string | How the summons and complaint were served. personal = Personal delivery; substituted = Substituted service (left with someone, then mailed); mail-outside-state = First-class mail to a defendant outside California; notice-and-acknowledgment = Notice and acknowledgment of receipt |
| stipulated_15_days | boolean | True if the parties stipulated to the rule 3.110(d) 15-day extension. |
| court_extension_days | integer | Days of any section 1054 court-ordered extension actually obtained. |
Compute the California Code of Civil Procedure section 437c deadlines that hang off a trial date: the last day a summary judgment motion can be heard (30 days before trial), the last day to file and serve it (81 days' notice plus the service extension; electronic service made on or after January 1, 2027 adds none), and the opposition and reply dates if the motion is heard on the last possible day.
| Argument | Type | Description |
|---|---|---|
| trial_date* | string | The trial date. |
| service_method* | string | How the moving papers will be served. Section 437c(a)(2) sets its own extension table, which is not the same as section 1013. |

}Work backward from a California civil trial date to the pretrial deadlines: the discovery cutoff and the motion cutoff, the expert exchange and expert discovery cutoffs, the last day to serve written discovery so responses are due before the cutoff, and the summary judgment dates. Optionally adds the local-rule deadlines for one of the counties this site tracks.
| Argument | Type | Description |

It sets the section 437c rows and the last day to serve a section 998 offer, which takes the section 1013 and 1010.6 extensions. No published decision applies section 1013(c) or 1010.6 to a 998 offer; the tool applies both on the reasoning of Lecuyer v. Sunset Trails Apts.

Omit for motions timed only off the hearing date. |

This is a different question from service_method and only this one extends the time to BRING the motion under section 1013. It never extends a period that runs from service of a summons: section 1016 takes service of a summons outside sections 1010.6 and 1013, so for a complaint served with the summons it is ignored.
