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."

  • If no notice of entry was served, use the 180-days-after-entry rule. AMBIGUITY: rule 3.1700(a)(1) does not state whether CCP 1013/1010.6 extends the 15 days when notice of entry is served by mail/electronically (contrast 3.1700(b)(1), which expressly applies them to motions to tax). Conservative setting: no extension. CCP 1013(a) extends the 15 days when notice of entry is served by mail (Nevis Homes, LLC v. CW Roofing, Inc. (2013) 216 Cal.App.4th 353, 356); 1010.6(a)(3)(B) adds 2 court days for electronic service by the same text. Filing within 15 days is safest. The 180-day outer limit (memorandum_of_costs_180) is not extended. [Validation 2026-11, Q0286. Authority: Nevis Homes, LLC v. CW Roofing, Inc. (2013) 216 Cal.App.4th 353, 356; Cal. Code Civ.
