It's not working for me and I don't know why. I'm getting errors in the function code: Type '(form: FormGroup) => { [key: string]: boolean; } | null' is not assignable to type 'ValidatorFn'.
Types of parameters 'form' and 'control' are incompatible.
Type 'AbstractControl' is missing the following properties from type 'FormGroup': controls, registerControl, addControl, removeControl, and 3 more.ts(2322)

If you compare these 2 dates with today then it will not work as today's getTime is always greater than the current day selected due to time factor.

Can you add logic to check for date validation which must be >= current date?
