You have 21 days from the date of arrest to become eligible for an adversarial preliminary hearing. This applies if you are still incarcerated. If you have been formally charged with a misdemeanor the state has 90 days to bring you to trial. If it is a felony they have 175 days. Good luck
The State does have 21 days from the date of arrest to file a formal charge so as to avoid an adversary preliminary hearing when the defendant has not made bond on a felony charge.
However, your question is about speedy trial and you are asking for a meaning of a cryptic notation in a case tracking system, which may include among other the scenario where 21 days remain before the expiration of the applicable speedy trial period, and the date is when a notice of expiration of speedy trial will be filed. The situations could be several others.
For example, if the case were to be a juvenile delinquency case, there is a 20 day period for a hearing (trial) where the child is detained pending disposition of the case, and the 21 days may be the date set for the trial.
You really need to talk with the Public Defender's Office to get a clear understanding of the annotation in its case tracking system.
Try contacting the public defender and asking him to explain his system. Good luck.
Otherwise, the time periods given by the other attorney for key events are correct.
Only a look at your clerk file can most accurately tell you what's going on procedurally in your case. Contact an attorney if you wish to consult on your case.
