- Count back 20 calendar days: Saturday, October 17, 2026.

Gov. Code 6800; Gov. Code 6707 (filings with a state agency); CCP 12, 12a, 13; agency rules 8 CCR 10600 (WCAB), 8 CCR 32130 (PERB), 22 CCR 5000 'Holiday' definition (CUIAB)
Gov. Code 6800: "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." Gov. Code 6707: "When the last day for filing any instrument or other document with a state agency falls upon a Saturday or holiday, such act may be performed upon the next business day with the same effect as if it had been performed upon the day appointed." 8 CCR 10600: "(a) The time in which any act provided by these rules is to be performed is computed by excluding the first day and including the last. (b) Unless otherwise provided by law, if the last day for exercising or performing any right or duty to act or respond falls on a weekend, or on a holiday for which the offices of the Workers' Compensation Appeals Board are closed, the act or response may be performed or exercised upon the next business day." 8 CCR 32130(a)-(b) (PERB): "(a) In computing any period of time under these regulations, except under Section 32776(c), (d), (e) and (f), the period of time begins to run the day after the act or occurrence referred to. (b) Whenever the last date to file a document falls on Saturday, Sunday, or a holiday, as defined in Government Code Sections 6700 and 6701, or PERB offices are closed, the time period for filing shall be extended to and include the next regular PERB business day. The extension of time provided herein shall be applied subsequent to the application of any other extension of time provided by these regulations or by other applicable law." 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."Official source
- Counting backward from a hearing or trial, when the day lands on a weekend or holiday we use the earlier court day. The rules do not state the direction expressly; confirm with the court.
- Exhibits must also be listed in the Pre-Trial Conference Statement at the MSC (8 CCR 10759(b); Lab. Code 5502(d)(3)), and discovery closes at the MSC. Runs from the trial date as set; a continued trial date presumably resets the count (not stated). Rule 8 CCR 10625 governs service methods, not exhibits. Backward roll direction not stated; previous business day is conservative.
- 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.
