WhereBetween query not working properly

I am trying to get the data between dates. I have used whereBetween() function when I search data for 10 days it gives me only 9 days of data...

I have set the database column data type as date.

and I am filtering on created_at field.

 $absent_count  = tbl_attendance::join("tbl_workers", "tbl_workers.worker_id", "tbl_attendances.attendance_worker_id")
 ->where("tbl_attendances.attendance_worker_presense", "A")
->where("tbl_workers.worker_id", $wrker->worker_id)
->whereBetween("tbl_attendances.created_at", [Carbon::parse($request->salary_from_date), Carbon::parse($request->salary_to_date)])->count();
