Formatting the way the date/time is displayed in Drupal 8

You can create a new date/time format by navigating to Admin -> Configuration -> Regional and Language -> Date and Time format and click on 'Add Format'. Once you’ve created date format, you can control the way date is displayed on the node using preprocess function.

In theme_name.theme file, add the following lines. This would override the way date is displayed in node.
