How to check string on date in laravel?

I want to handle the situation if string doesn't date for example like "it's some not date string".

I try it code, but it doesn't work I have next error:

InvalidArgumentException  : A two digit month could not be found
Data missing

My code:

    if (Carbon::createFromFormat('m-d-Y', $rowMatrix[4]) !== false) {
//
}
