Create a chronological timeline

create your timeline with dates and make each date a movieclip. 

on each date's inital frame, just put what you want displayed by default.  add a this.stop() to that initial frame's actions panel.  create another frame (labeled eg, "clicked" that shows what you want displayed if that date is clicked.  (before spending a lot of time on the "clicked" frame, check what it looks like by taking the steps below.  you'll most likely find you want a background for the clicked frame and/or you want to reposition the "clicked" frame contents.)

on the main timeline put each date movieclip on the timeline where you want it positioned, and assign it an instance name (eg, date_10202022).  on the main timeline actions panel use:

this.date_10202022.addEventListener("click", dateF.bind(this);

function dateF(e){

if(e.currentTarget.currentFrame==0){

e.currentTarget.gotoAndStop("clicked");

} else {

e.currentTarget.gotoAndStop(0);

}

}

//////////////////////

the same dateF can be used for all your date movieclips.  they all need a different instance names and they all need listener functions.

eg, if you had todays date 10/20/2022 and the previous 3 days date, in addition to the code above, use:

this.date_10192022.addEventListener("click", dateF.bind(this);

this.date_10182022.addEventListener("click", dateF.bind(this);

this.date_10172022.addEventListener("click", dateF.bind(this);
