Working with dates and time in WIX Code?

Andreas can you help me out with the code and/or where it should go to do that? I’m surprised I got this far… I’m not entirely sure how to move forward

  1. Would the Function be on the page code or the data.js?
  2. What would that code look like
  3. How do I format the date correctly – I see the split/splice method a lot and I read Wix’s articles but not sure I understand how those work on the dates, and with your method, I’m not sure how to change the XX/XX/XXXX format to Mon XX 201X

Thanks again!
