(a) A judge to whom cases are assigned under the individual assignment system may establish such calendar of cases as the judge shall deem necessary or desirable for proper case management.

In any court not continuously in session, the calendars at the close of one term or session of court shall be used to open the following term or session, and actions on the calendars shall retain their positions.

A military calendar shall be utilized to hold in suspense an action that cannot reasonably be tried because a party or a witness necessary upon the trial is in military service and is not presently available for trial, and a deposition cannot be taken, or, if taken, would not provide adequate evidence.

With due regard to the requirements of statutory preferences and of section 210.20 of this Part, when actions are advanced from one calendar to another they shall progress from the head of one calendar to the foot of the next calendar, and otherwise progress in order, insofar as practicable, unless otherwise determined by the court.

Judges to whom actions and proceedings are assigned pursuant to the individual assignment system may schedule calls of any calendars they have established at such times as they deem appropriate.

When an action has been announced “ready” but a trial is not immediately available, counsel may arrange with the judge to be summoned by telephone, provided they agree to hold themselves available and to appear on one hour's notice, or at such other time as the court may order, at the time assigned for trial.
