Hi,
thanks for using MH Magazine lite.
The premium version of MH Magazine comes with options to hide post meta data, amongst several other additional features, options and custom widgets to configure your website. For the free theme, you either would need to code a custom child theme based on your personal requirements or hide the date with CSS.
When it comes to CSS customizations, you can always use your browsers inspection tool to inspect the elements on your site and then use that information to add your own code modifications, for example:
.entry-meta-date { display: none; }
You can add CSS code in your WordPress dashboard under Appearance => Customize => Additional CSS.
