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 350: "An action is commenced, within the meaning of this Title, when the complaint is filed."

  • Displaces CCP 337.1 and 337.15 for SB 800 claims. Tolling under Civ. Code 927 (sb800_927_* rules) applies; SB 800 repairs otherwise do not extend the period (941(e)). The clause 'but not later than the date of recordation of a valid notice of completion' is textually unclear; lawyer should review how substantial completion is fixed.
  • 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.

Worked example

Date of substantial completion of the improvement, or the date a valid notice of completion was recorded if that is earlier on Monday, March 15, 2027, personal service: due Monday, March 16, 2037.

  1. Trigger (Date of substantial completion of the improvement, or the date a valid notice of completion was recorded if that is earlier): Monday, March 15, 2027.
  2. Add 120 months: Sunday, March 15, 2037.
  3. That day is a Sunday, so the deadline moves to the next court day: Monday, March 16, 2037 (Cal. Code Civ. Proc. 12, 12a, 12b, 350).

Notes

Displaces CCP 337.1 and 337.15 for SB 800 claims. Tolling under Civ. Code 927 (sb800_927_* rules) applies; SB 800 repairs otherwise do not extend the period (941(e)).
