The dates are worked out from the publication dates and the authors' deaths. In the United States a book published before 1978 is protected for 95 years after publication, and a later one for 70 years after its author's death; in Canada a book is protected for 70 years after its author's death. Protection runs to the end of the year, so a book enters the public domain on 1 January.
