Laravel - do I need a service provider for each of my containers / user classes?

Question

Service containers / suppliers are probably much simpler concepts than I can imagine, but after hours of reading I still don't get it completely.

I created a simple class DateFormatinside app/Library. After creating an alias for it inside, \config\app.phpI can use it right away in any controllers or blade templates.

<?php namespace App\Library;

class DateFormat {

    public static function getDate($timestamp){
      // processing the timestamp      
    }

}

Did I just create a services container? If so, do I also need to create a service provider? Where are the bindings to the picture?

I would really appreciate covering this topic. Thanks
