You can get the remain days like this:

DB::statement("SELECT (course-duration - DATEDIFF(NOW(), created_at)) remained FROM your_table");

You can use Carbon to get the value of days between created_at and now

$diff_from_now = Carbon::parse($course->created_at)->diffInDays();

$course_duration = $course->duration;

$remaining_days = $course_duration- $diff_from_now;

Just define a method in your Course model to calculate remaining days of each course:

class Course extends Model

{



    public function remainingDays() {

        return $this->course-duration - $this->created_at->diffInDays(Carbon::now());

    }



}

And to get remaining days of every course:

$course->remainingDays();
