Thank you for your comment. My problem is that some of the dates in my GEDCompare file are formatted like this "DDMTHYYYY," i.e., 20Aug1905 or 06Sep1936, etc.
Apparently WikiTree does not read that very common date format. I would like to be able to change the dates so they are readable without having to go back and change the source file.
I wish there were some easy way to do that.
