NaN in adjecant month fix

Hey guy’s, when updating wordpress to a version above 5 the calendar shows NaN for adjecant months. You can fix this by updating the cldnr framework. You can do this by replacing the code at: /wp-content/plugins/event-clndr/libs/clndr/clndr.min.js (v 1.4.6) by the github version https://github.com/kylestetz/CLNDR/blob/master/src/clndr.js (currently 1.4.7). Hope it helps you out.
