Why Am I Seeing an ‘Invalid Date’ Error on the Checkout Form When There’s No Date Field on the form?

If you are just getting Invalid date with Birthdate field on the form, please see THIS FAQ

This is for the error “Invalid Date” or “Birthdate: invalid date” on the checkout form:

What's causing the issue:
In recent updates (Feb 2020) with Salesforce there have been some errors with date fields. If there had been a date field that was previously filled in, the autofilling component on the browser has retained the information, even if the field is no longer on the checkout form.

How do I fix it?
Find the history section of the browser and clear history of the Autofill options. Some browsers might have different names for these actions.
