(a) Grand Jurors. The Chief Judge or his designate shall certify to the Clerk of the Court the number of grand jurors required each month. Persons summoned for service as grand jurors shall be called for the first Monday of each month (or if the first Monday be a holiday, then the next business day of this Court) and shall serve for a period of one month and until the impaneling of the next regular Grand Jury of the following month. The court, on its own motion or on petition of the State's Attorney or the foreman and 11 other grand jurors, may for good cause extend the term of any Grand Jury from time to time for successive periods of not more than 30 days each. No such Grand Jury shall serve in excess of 18 months and not more than six Grand Juries shall sit at the same time.

(b) Petit jurors. The Chief Judge or his designate shall certify to the Clerk of the Court the number of petit jurors required each month. Persons summoned for service as petit jurors shall be called for each day of each week and shall serve for one day unless during that day they are impaneled as jurors in a trial. In the event of such impanelment, the person so impaneled shall serve for the length of the trial and then be excused. Any judge or associate judge may extend the term of any petit jury or jurors from time to time as justice may require.
