Date formating in Line Schedule Viewer

If I have to change the format of the date in the header on Line Schedule View, What is the best possible way? I tried playing around with the components, but I was not able to figure out where I can find the attributes/ objects of the header to change the name. For example, in the below attachment, we have to change the header on the second row where it currently says “Sunday” to a date format. I need to write to the script, but I don’t know how the header is binded?

What version of Ignition are you using? The second row on mine defaults to (EX:) Thursday 16.
