The original title for this album was God's Greatest Hits but management at RCA Records didn't approve.

The title is a punning spelling of "Do It On Monday," playing on the British Monarchy's motto Dieu et mon droit (God and my right).

Duit on Mon Dei marks the first time Nilsson acted as his own producer.

Due to the record's eclectic sonics, critic Robert Christgau (negatively) likened Nilsson's production style to "an audio salesman".

Club retrospectively dubbed Duit on Mon Dei "vastly underrated".
