The Arizona deadline engine
Every Arizona clock computed by a pure, unit-tested function — the trigger day excluded, the last day rolled (Rule 6(a)), legal holidays flagged as the per-court fact they are, and the citation attached. Arizona's computation twist: intermediate weekends and holidays are excluded only when the period is UNDER 11 DAYS — a threshold no other state uses — and the Rule 6(c) mail addition counts weekends inside its five days. Both encoded from the verbatim rule, both pinned by a release gate. Times resolve to America/Phoenix — no daylight saving, with the Navajo Nation exception noted.

The 180-day notice-of-claim trap (A.R.S. § 12-821.01) and the one-year public-entity bar (§ 12-821) run TOGETHER against government defendants — two clocks, both shorter than the ordinary limitations ladder. Every formula above must survive verbatim in the loaded corpus or the release gate fails.
