A calendar is the court's official schedule that lists when your case and others will be heard or decided.
In a court case, the calendar is a formal list of cases set for a specific day, session, or term, often published by the court clerk. It appears in the court's docket or online system and shows the order in which matters will be called.
It tells you exactly when you or your lawyer must appear in court, so you do not miss a hearing. Being unaware of a calendar date can lead to serious consequences, such as a default judgment or dismissal.
People often think a calendar is just a personal reminder, but in court it is a binding procedural document set by the court. It is also sometimes confused with the 'docket,' which is a more detailed record of all filings and events in a case.
