How to count court days in California: deadlines, holidays, and service

Nine court days before a hearing is not the same as nine days before a hearing. It also does not mean “about two weeks.” A single holiday can move the filing date earlier than someone expects.

The arithmetic is manageable once the inputs are right. Before counting, identify the governing rule, the event that starts the calculation, whether the rule uses court days or calendar days, and whether a court order sets a different schedule.

For many ordinary noticed motions, Code of Civil Procedure section 1005(b) supplies the familiar framework: moving papers at least 16 court days before the hearing, opposition at least nine court days before, and reply at least five court days before. Those are baseline intervals, not a universal schedule for every motion. Section 1005 expressly recognizes other law and court orders.

First, identify the kind of day

Calendar days include weekends and holidays within the counting period. The rule governing the last day then determines what happens if the calculated due date falls on a noncourt day.

Court days generally exclude Saturdays, Sundays, and judicial holidays. Use the California court holiday schedule and the relevant court's notices. Your firm's office calendar and a federal holiday calendar may not match the state court calendar.

An unexpected closure needs a separate check. A portal outage, a department's dark day, and an emergency order affecting statutory time are different events. Read the applicable order or notice before treating a date as excluded or a deadline as extended.

Counting backward: a nine-court-day opposition deadline

Assume an ordinary motion governed by section 1005 is set for Monday, November 23, 2026, with no order changing the briefing schedule.

Section 12c directs the backward count to exclude the hearing date. Veterans Day falls on Wednesday, November 11, and is a California court holiday. The following count therefore skips that date as well as both weekends. The holiday is confirmed on the California courts' 2026 holiday schedule.

Under those assumptions, the opposition must be filed and served no later than Monday, November 9. The five-court-day reply date is Monday, November 16. Section 1005(c) also governs how opposition and reply papers must be served; calculating the filing date does not finish the service analysis.

Counting forward uses a different starting point

Suppose, purely as an illustration, an order requires an act ten calendar days after personal service. Assume service occurs Friday, November 6, 2026, and no other rule or extension applies. Exclude November 6 and count November 7 as day one. Day ten is Monday, November 16. The intervening weekends and Veterans Day stay in this calendar-day count.

If the order instead used court days, the answer would change. If the triggering document were served by a different method, an applicable service extension might also change the answer. Record those inputs rather than retaining only the resulting date. Rule 1.10 explains the general computation framework for acts governed by the Rules of Court; the statute or order governing the actual obligation remains essential.

Service extensions are a separate calculation

For section 1005 moving papers, the statute itself provides additional notice for certain service methods. For example, qualifying mail service wholly within California adds five calendar days. Section 12c(b) directs you to count applicable additional service days backward from the baseline date.

Do not automatically add section 1013 time to every motion deadline: section 1005 expressly excludes its general extension for the motion, opposition, and reply papers governed by that section. Nor does an electronic-service extension simply give a party two more days to file a hearing-based opposition.

Electronic-service timing is changing. The 2026 version of section 1010.6(a)(3) contains a two-court-day extension for covered notice and response periods, subject to exceptions. AB 540, chapter 263 of the 2026 statutes, removes that general extension and revises sections 1005 and 437c for 2027. For a calculation spanning that change, confirm the effective version and its application to the service at issue. A saved “add two days” formula is not enough.

A checklist to keep beside the calendar

• Identify the exact motion or obligation and governing authority.
• Confirm the hearing, service, filing, or other triggering date from its source.
• Read any order setting or preserving a separate schedule.
• Mark the count as forward or backward, and court days or calendar days.
• Exclude the triggering day where the applicable rule requires it.
• Check judicial holidays and any relevant emergency order.
• Apply only the service extension that actually governs.
• Confirm filing requirements and service requirements separately.
• Save the rule, inputs, skipped dates, and reviewer with the result.
• Revisit the calculation if the underlying event changes.

A reliable deadline is a date someone else can reconstruct. AlwaysPresent helps teams identify court activity that calls for that review. Its planned deadline tools are intended to make the rule and calculation visible alongside the result. Explore AlwaysPresent.
