Try these steps:

1- Middleware

first of all you should create a middleware in app/Http/Middleware:

 'toGregorian',
        'created_at' => 'toDateTime',
    ];

    protected function transform($key, $value)
    {
        if (!array_key_exists($key, $this->fields)) {
            return $value;
        }

        $function = $this->fields[$key];

        return call_user_func($function, $value);
    }
}

with this middleware you can define fields that you want to manipulate them before calling validation and call a specific function to manipulate them.

note: i defined toGregorian and toDateTime in my own helper functions. you can handle it with your own functions

2- Kernel

then modify Http/Kernel.php like bellow:

protected $middlewareGroups = [
    'web' => [
        ...

        \App\Http\Middleware\EnglishStrings::class,
    ],

    'api' => [
        ...
    ],
];
