Well, here is what you asked for, but it may not be when you need.
You can use a form rule
When the Record is saved
Condition
[date] is before "the current date"
Action
Abort the save with a message "Sorry, but dates must not be in the past"
But the issue to consider is that though the passage of time, all dates will eventually be in the past, so no one will be able to edit the record. So,there will need to be more to this setup depending what your use case is.
Is this just for when the record is initially created?
