How do I get the difference of time in human readable format with Laravel 5?

incase of the date is in a string format, use laravel Carbon; e.g,

 {{ \Carbon\Carbon::parse($on_revision->assignment->deadline)->diffForhumans() }}

Notice how I wrap my string in the carbon::parse()

By default, Eloquent converts created_at and updated_at columns to instances of Carbon. So if you are fetching the data using Eloquent, then you can do it as below.

$object->updated_at->diffForHumans();

If you want to customize the fields that will be mutated automatically, then within your model, you can customize them as you wish.

// Carbon instance fields
protected $dates = ['created_at', 'updated_at', 'deleted_at'];
