I am wondering how to tell the TimelinePlot function to display the day name for the dates that are displayed with the the tooltip.
I think the option that would be used is LabelingFunction but I'm not sure how to specify the function.
I would like the tooltip to display the dayname day month year like Monday 18 February 2002. I read the documentation for LabelingFunction for TimelinePlot but I couldn't figure it out. This code outputs a date object formatted the way I want it:

DateObject[Now, "Day", DateFormat -> "Date"]

This is the output:

DateObject[{2022, 12, 
  14}, "Day", "Gregorian", -5., "SmearedUTC", "Date"]
