Rule to hide fields when an invalid date is manually entered

Good afternoon!

Sounds simple but I've hit a roadblock. I'm looking for a simple rule for field definition that would hide the rest of a form if the a date field was manually entered incorrectly. 

For example, I'm using the default formatting of (MMM dd, yyyy) so calendar picked dates should work without issue, however, if someone were to type in "01/01/2020" or "qwerty" I'd want the rule to kick in, hide the form and pop up an error info field. Is there a quick and easy way to do this?

You can validate your date, and it's timestamp property in particular

As the date that cannot be parsed usually is set to January 1st 1970 at midnight GMT (Greenwich Mean Time) 

So, you can check if it is larger than that or not (which is 0 timestamp)

Something like this: 


This is great! Works well, but what if a user types in a number, like "1" or "123"? Since the date field is numeric, the timestamp logic doesn't appear to catch just a random number. Is there a workaround to prevent that?

You can make it validate agains some other value than 0

For example, the date should be not before January 1 2021

Checking that it is larger than 1609459200000
