What does criminal docket mean?

Mr. Chase is correct. It depends on what court you are in but it helps the court organize whether something is criminal, civil or a traffic matter, as many judges handle all types of cases. If you are on a criminal docket and have questions about the proceedings, you should hire an attorney to represent you, as things are only going to get more technical and complicated as you move forward. An attorney will not only answer your questions, but will also ensure that your rights are being protected. Further, most criminal offenses carry potential jail time, as well as other consequences, which a lawyer is better trained to help you avoid.

The docket is just referring to the queue in which all the cases in a particular court sit until ready for trial. It also refers to the particular case's activity, so case number so-and-so is on the docket for trial 12/12/2013. Its docket entries include all activity on that case.
