- Trigger (Date the due process hearing is scheduled to begin): Friday, November 6, 2026.
- Count back 5 calendar days: Sunday, November 1, 2026.
- That day is a Sunday. Counting backward, this calculator uses the earlier court day so the full notice period is preserved: Friday, October 30, 2026 (see No general agency rule for counting backward. By analogy to CCP 12c.).

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.

- 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.
- IDEA timelines are in calendar days unless stated as business or school days (34 CFR 300.11). Hearings are conducted by OAH Special Education Division under contract with CDE (Ed. Code 56504.5). Deadline for the order granting permission, so a motion must be filed earlier. Amendment restarts all timelines.
- 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.
