I've been using this great program for three months now! I don't have any portable devices, but finally I have a program that organizes my books in Linux
"Unknown Month", ("Unknown_day",) "Unknown_Year" are not Valid Date types


Note that Calibre can perform 'date arithmetic' searches on date (field type) values

1/1/101 (localized) is a assigned as a 'Unknown Date' marker.
