valid_date[d/m/Y] doesn't validate year properly

I am trying to validate a date field using validation rules

Code:

'date' => 'required|valid_date[d/m/Y]'

and it accepts as a year any integer value. It can be from 0 until 9999.
Shouldn't it be according to "Y" validation of a full year like 1995 or 2022?

Year 0 and Year 9999 are valid year.

Thanks, I agree with that.
Any suggestions how to limit the year to let's say 2000?
Unless I create my own custom date validation.

Didn't look at it closely but it would be trivial to implement a custom validation method. You can check the documentation for an example.
