Missouri State Courts Litigation Deadline Calculator

Deadlines in Missouri State Courts are computed using Mo. Sup. Ct. R. 44.01. The calculator excludes the trigger day, counts forward (or backward) the specified number of days, and adjusts for weekends and court holidays. If the resulting date falls on a non-business day, the deadline rolls to the next business day.

Missouri State Courts observes all state-designated court holidays when computing deadlines. These typically include New Year's Day, Martin Luther King Jr. Day, Presidents' Day, Memorial Day, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving, and Christmas Day. Some states observe additional holidays specific to their jurisdiction.

Mo. Sup. Ct. R. 44.01 is the procedural rule that governs how time periods are computed in Missouri State Courts. It defines how to count days (calendar vs. business), when to exclude weekends and holidays, and how to handle deadlines that fall on non-business days.

When a document is served by a method other than hand delivery or electronic means, additional days are typically added to the response deadline. For example, service by U.S. Mail usually adds 5 days. The exact add-on depends on the jurisdiction's rules and the specific service method used.
