  • trial_continuance 'follows': the text runs from 'the trial', not an initial trial date. Applies to both prosecution (1054.1) and defense (1054.3) disclosures. Material learned within 30 days of trial must be disclosed immediately (not a day count). Good cause is limited to threats to victim or witness safety, possible loss of evidence, or compromise of other investigations. Constitutional (Brady) obligations are not limited by this period. Backward roll: previous court day.
  • 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.

Worked example

Trial date on Monday, March 15, 2027, personal service: due Thursday, February 11, 2027.

  1. Trigger (Trial date): Monday, March 15, 2027.
  2. Count back 30 calendar days: Saturday, February 13, 2027.
  3. That day is a Saturday. Counting backward, this calculator uses the earlier court day so the full notice period is preserved: Thursday, February 11, 2027 (see Cal. Code Civ. Proc. 12c).
