Could FamilySearch do anything to prevent incorrectly formatted dates appearing in indexed records?
Not having any experience of programming, I will take the risk of making myself look stupid here, but I raise this question following the post at https://community.familysearch.org/en/discussion/153153/why-are-thousands-of-danish-1921-census-dates-of-birth-indexed-wrongly#latest.
As most of us know, the problem referred to is not that unusual in itself (see example below), albeit it does not usually affect every record in a whole collection. So, my simple question relates to the complexity of running a check for such dates appearing in a collection before FamilySearch puts them online. Is it so difficult to write a piece of code that would expose such errors, thus allowing for corrective work before a collection goes online and researchers are faced with the resultant problems?
The date range I have inputted shows at least 908 errors of this kind in this collection.
Perhaps anyone with programming experience could advise of the feasibility of any action that could prevent dates appearing in this form in future.
