FA-77556 / Legal deadline computation / Open access
Earliest hearing date after court-day notice plus mailing days: court day test · case 01
A holiday inside the notice period is counted as a court day.
ROOT CAUSE
Court days are identified by weekday alone.
VERIFIED REPAIR
At the court day test decision use `not closed(d)`, leaving the other decision sites of the model unchanged.
Unsuccessful approach: The partial repair `d not in hol` counts weekends as court days.
Case contract
Stipulated: a motion must be served at least notice_days court days before the hearing. Excluding the service day, count notice_days court days (not Saturday, Sunday or a listed holiday); then add calendar days for the service method (mail 5, mail-out-of-state 10, express 2, otherwise 0). If that day is not a court day, the earliest hearing is the next court day.
Why this case matters
Docketing systems compute filing and response deadlines from trigger events; a wrong date can forfeit a right.

Verification & scope
Stipulated toy deadline rules evaluated offline on explicit fixtures. The contract is inspired by common court-rule structures but is not legal advice and makes no claim to reproduce any jurisdiction's rules. This reproducer isolates one failure mechanism. Results cover the supplied fixtures. Variants within a family share a test contract and should remain grouped when constructing evaluation splits. Related mechanisms with a shared evaluation_group must also remain together; these controlled models are not independent production incidents.
