Date format on the blog – possible to change? I'm in the UK!

Site URL: http://alextreadway.co.uk/journal

Does anyone know how to change the date format on blog pages? Right now it's:

Wednesday 10.13.21

I'm in the UK so would be much better like this for example: 

13th October 2021

Is there a fix somehow? 

Thanks

So after some experimenting with other posts I've solved this. Solution here. Ad this code to settings/advanced/code injection 

See pic attached shows result

<!-- Fix inconsistent blog date format on Squarespace 7.1 template -->
<!-- Squarespace Forum 03-08-2021 -->
<script src="https://stevenlevithan.com/assets/misc/date.format.js"></script>
<script>
	document.addEventListener('DOMContentLoaded', function() {
      var dateformat = "dd mmmm yyyy";
      var pubdate = document.querySelectorAll("time[datetime], time[pubdate], time.blog-meta-item--date");
      for (var i = 0; i < pubdate.length; i++) {
          var d = new Date(pubdate[i].getAttribute("datetime") || pubdate[i].innerText);
          if ( pubdate[i].classList.contains('blog-meta-item--date') ) {
              d = new Date(document.querySelector('[itemprop="datePublished"]').getAttribute("content").split("T")[0]);
          }
          pubdate[i].innerHTML = d.format(dateformat); 
      }
  });


</script>

As additional info, you can edit any other format by editing the line

      var dateformat = "dd mmmm yyyy"
