When a California filing deadline lands on a judicial holiday or a weekend, Code of Civil Procedure Section 12a pushes it to the next day the court is open.1California Legislative Information. California Code of Civil Procedure CCP 12a That automatic extension is the main way California judicial holidays affect filing deadlines, and it works reliably as long as you are counting against the right calendar. California keeps two overlapping holiday lists, and only one of them closes the courts.
Which Days Actually Close California Courts
Code of Civil Procedure Section 135 is the controlling list for court closures.2California Legislative Information. California Code of Civil Procedure CCP 135 Section 135 starts from the full-day holidays in Government Code Section 6700, carves out several of them, and adds Saturdays and the day after Thanksgiving.
The days California courts close each year:
- Every Saturday and Sunday
- New Year’s Day (January 1)
- Martin Luther King, Jr. Day (third Monday in January)
- Lincoln Day (February 12)
- Washington Day (third Monday in February)
- César Chávez Day (March 31)
- Memorial Day (last Monday in May)
- Juneteenth (June 19)
- Independence Day (July 4)
- Labor Day (first Monday in September)
- Native American Day (fourth Friday in September)
- Veterans Day (November 11)
- Thanksgiving Day (fourth Thursday in November)
- Day after Thanksgiving (fourth Friday in November)
- Christmas Day (December 25)
Any day the Governor proclaims a public holiday is also a judicial holiday.3California Legislative Information. California Government Code 6700 Presidential proclamations, on their own, do not close California state courts.2California Legislative Information. California Code of Civil Procedure CCP 135
State Holidays That Do Not Close the Courts
This is where filers most often get burned. Government Code Section 6700 lists more than 20 state holidays, but Section 135 explicitly excludes several of them from the judicial calendar.2California Legislative Information. California Code of Civil Procedure CCP 135 The following are state holidays but not judicial holidays:
- Lunar New Year
- Genocide Remembrance Day (April 24)
- Admission Day (September 9)
- Columbus Day
- Any day declared a holiday by the President alone
Good Friday is a partial state holiday (noon to 3 p.m.) under Government Code 6700 and therefore does not qualify as a full-day judicial holiday either.3California Legislative Information. California Government Code 6700 On any of these days, the clerk’s office is open and processing filings. Your deadline does not shift.
How the Rollover Actually Works
Three sections of the Code of Civil Procedure do the counting work. Section 12 sets the baseline rule: exclude the first day of the period and include the last day.4California Legislative Information. California Code of Civil Procedure CCP 12 Served with a complaint on March 3 with 30 days to answer? Start counting on March 4.
Section 10 defines what “holiday” means for the counting rules — every Sunday plus every judicial holiday in Section 135.5California Legislative Information. California Code of Civil Procedure CCP 10 That definition ties deadline math to the judicial calendar, not the state calendar.
Section 12a is the extension itself. If the last day to perform a legally required act is a holiday, the deadline moves to the next day that is not a holiday.1California Legislative Information. California Code of Civil Procedure CCP 12a For Section 12a’s purposes, “holiday” includes all Saturdays and all Section 135 judicial holidays.
The reach of Section 12a is broad. It applies to deadlines set by any California code, statute, ordinance, rule, or regulation, and it specifically covers motions for new trial under Sections 659 and 659a and notices of appeal under Section 921.1California Legislative Information. California Code of Civil Procedure CCP 12a It also protects statutes of limitations. If the last day to file suit is a Sunday or Thanksgiving, filing on the next court day preserves the claim.
One boundary worth knowing: Section 12a protects deadlines imposed by law, not deadlines set by private agreement. A contractual deadline that lands on a Saturday generally stays on that Saturday unless the contract says otherwise.
Acts Due on a Specific Date
Section 13 handles a slightly different case. When a law or contract requires an act on a specific calendar date and that date happens to be a holiday, you can perform the act on the next business day with the same legal effect.6California Legislative Information. California Code of Civil Procedure 13 Section 12a covers a running period that ends on a holiday; Section 13 covers a fixed date that happens to be a holiday.
Filing After Hours or on Weekends
Both e-filing systems and courthouse drop boxes accept documents outside business hours, and both use similar rules about which date lands on the filing stamp.
Electronic Filing
Many California superior courts require electronic filing for civil cases under California Rules of Court, Rule 2.253.7Judicial Branch of California. California Rules of Court 2.253 – Permissive Electronic Filing, Mandatory Electronic Filing, and Electronic Filing by Court Order The e-filing system will send a confirmation timestamp when it receives a document, but the receipt timestamp and the official filing date are not always the same. Documents transmitted on a judicial holiday or weekend are generally recorded as filed on the next court day. The confirmation proves you sent it; it does not by itself establish the filed date.
Courthouse Drop Boxes
Rule 2.210 sets the cutoff for paper filings deposited in courthouse drop boxes.8Judicial Branch of California. California Rules of Court 2.210 – Drop Box for Filing Documents A document placed in the box by 4:00 p.m. on a regular court day is deemed filed that day. Some courts post a later same-day cutoff, but they must give notice of the extended time.
Documents deposited after 4:00 p.m. on a court day, or at any time on a judicial holiday, are deemed filed on the next court day.8Judicial Branch of California. California Rules of Court 2.210 – Drop Box for Filing Documents There is no back-dating. Papers dropped Saturday get a Monday filing date, assuming Monday is not itself a holiday.
Court Days vs. Calendar Days
Some California deadlines are measured in “court days” rather than calendar days. Court days exclude weekends and judicial holidays entirely from the count, so a five-court-day deadline can span more than a week on the calendar. Section 12c governs backward-counted deadlines measured in court days, such as the requirement to file certain motions a specified number of court days before a hearing.9California Legislative Information. California Code of Civil Procedure 12c – Time for Performance of Act Read the underlying rule carefully to see which kind of day it uses. A motion counted in court days but calculated as if in calendar days will land in front of the court too late to be heard.
When the Court Is Unexpectedly Closed
Wildfires, earthquakes, power outages, and e-filing crashes all happen on days that were supposed to be regular court days. California superior courts handle unplanned closures through presiding judge orders and, in statewide crises, emergency rules issued by the Judicial Council. Filings due during those closures are treated the same way as filings due on a judicial holiday: the deadline shifts to the next day the court is open. If you know your courthouse is closed because of an emergency, save screenshots of closure notices or e-filing error messages and file as soon as the court reopens.
Federal Court in California Is a Different Calendar
If your case is in federal court rather than state superior court, the judicial holiday list above does not control. Federal courts follow the holiday list in Federal Rule of Civil Procedure 6(a)(6), which includes Columbus Day (California state courts do not) and omits several California-specific closures such as César Chávez Day, Lincoln Day, Native American Day, and the day after Thanksgiving.10Legal Information Institute. Rule 6 – Computing and Extending Time; Time for Motion Papers
The federal rule uses the same rollover approach as California’s: if the last day is a Saturday, Sunday, or legal holiday, the deadline moves to the next day that is none of those. Rule 6(a)(1) adds a wrinkle for deadlines measured after an event — any state holiday where the district court sits also counts as a legal holiday, so a federal court in California effectively picks up the California judicial holiday calendar for certain post-event deadlines on top of the federal list.10Legal Information Institute. Rule 6 – Computing and Extending Time; Time for Motion Papers Rule 6(a)(3) also protects filers when the clerk’s office is inaccessible on the deadline day, extending time to the first accessible day that is not a Saturday, Sunday, or legal holiday. The advisory committee notes treat e-filing outages as a form of inaccessibility.
Litigants with cases in both systems need to track both calendars, because a day the state courts close is often a day the federal courts are open, and vice versa.
The Practical Safety Margin
The safest habit around any deadline that lands near a holiday cluster is to file at least one business day early. Thanksgiving is the sharpest example on the California calendar: the courts close Thursday and Friday, so a Wednesday deadline followed by weekend rollover under Section 12a can leave a four-day gap during which nothing gets filed and nothing gets accepted. Building in a day of margin costs nothing and prevents the worst kind of missed deadline — the one where you thought the rollover rule was going to save you.
