The term 'courtroom calendar' is a reference to the DOCKET, which is a list of cases that are scheduled to be heard in a courtroom. The DOCKET is typically organized by date and includes information about the parties involved in each case, the type of case, and the judge assigned to the case. The DOCKET is an important tool for court administrators, attorneys, and judges, as it helps them keep track of upcoming cases and ensure that all parties are prepared for their hearings.
