Firstly, you can not validate route parameters inside Form Request

But, you can use regex for validating your route Example:

Route::get('/calendar/{day}', 'App\Http\Controllers\HomeController@calendar')
    ->name('calendar')
    ->where('day', '/^[0-9]{4}(0[1-9]|1[0-2])(0[1-9]|[1-2][0-9]|3[0-1])$/');

If You still want to use validate() function or Form Request

$request->merge([
   'day' => $day
]);

$this->validate($request, [
   'day' => 'date_format:Ymd',
]);

Form Request Way - Override all() method

public function all($k = null){
   $data = parent::all($k);
   $data['day'] = $this->route('day');
   return $data;
}

If Nothing Works, Try Following code

public function calendar(Request $request, $day){
 $data = $request->all();
 $data['day'] = $day; 

 $validator = Validator::make($data, [
   'day' => 'required|date_format:Ymd',
 ]);
  
 if($validator->fails()){
    // Do Something abort(404);
 }

}
