Missouri Deadline Rules

Deadlines are computed from Missouri Rules of Civil Procedure (Mo. R. Civ. P.), Missouri Rules of Civil Appellate Procedure, RSMo, and Missouri Supreme Court Operating Rules, versioned and dated in the rule data
How you were served is part of the calculation — the calculator applies the extension the rule gives that method, including none
Weekends and Missouri court holidays are applied when a computed date lands on one
Every computed deadline carries a conservative safety buffer, and ambiguity resolves to the earlier date
Enter your dates in the calculator for a result specific to Missouri — periods depend on the trigger event and how you were served
