/**
 * Code goes in theme functions.php

 * Add automatic NEW badge for x amount of days.
 *
 * Keep caching in mind! If you want to automatically update it on the frontend by using caching, you might want to look
 * into a cron job that clears cache each day f.ex. https://docs.wp-rocket.me/article/494-how-to-clear-cache-via-cron-job
