Is it possible to obfuscate php output of date in blog

@joel-marks, I've had a quick look at Open Publishing and think the following will do what you are after:

• Copy file '/user/themes/quark/templates/partials/blog/date.html.twig' to '/user/themes/mytheme/templates/partials/blog/date.html.twig'.
• Replace the contents with:
  TWIGCopy

  <span class="blog-date">
    <time class="dt-published" datetime="{{ page.date|date("Y-m") }}">
        <i class="fa fa-calendar"></i> {{ page.date|date('Y-m') }}
    </time>
  </span>
  

• The dates in the blog-item-list and each blog-item will now be: 'Y-m', or '2020-03'

Other date formats can be found at https://www.php.net/manual/en/function.date.php.
To set a different date format, replace 'Y-m" on line 3 with any combination found at above link, or below:

• 4-digit year: Y (2020)
• 2-digit month: m (01 - 12)
• Full textual month: F (January through December)
• A short textual representation of a month: M ( Jan through Dec)

Eg.

• 'January 2020': 'F Y'
• 'Jan 2020': 'M Y'
• '2020/03': 'Y/m'

Hope this helps...
