The dating of this book is one of the most controversial subjects in the field of Old Testament Introduction. The controversy is not due to the obscurity of evidence but to the presuppositions of critics.
It is quite easy to determine when Daniel lived and ministered because of the many historical references in this book. His fellow prophet Ezekiel also referred to him (cf. Ezek. 14:14, 20; 28:3). However because the book contains prophecies that Antiochus Epiphanies fulfilled in the second century B.C. many rationalistic critics who deny that the Bible contains predictive prophecy have said that Daniel could not have written it. They contend that it must have been written after Antiochus, namely, about 165 B.C. However there are many evidences within the book itself that point to its origin in the sixth century B.C.5This modern criticism follows Porphyry's view. However no significant writer espoused a late date for the book after Jerome refuted Porphyry until the eighteenth century A.D. J. D. Michaelis revived Porphyry's theory in 1771, and it took root in the rationalistic intellectual soil of the Enlightenment. Since then many scholars who disbelieve in predictive prophecy have insisted that this book must have been the product of the Maccabean revolt (168-165 B.C.). Liberal critics still consider the late dating of Daniel to be one of the most assured results of modern scholarship. Nevertheless there is ample evidence in the book itself that Daniel wrote it and that it dates from the sixth century B.C.6
"One who claims that the book of Daniel is a product of the Maccabean age thereby denies that it is a work of true predictive prophecy as it purports to be. Furthermore, if the book of Daniel comes from the age of the Maccabees, I do not see how it is possible to escape the conclusion that the book is also a forgery, for it claims to be a revelation from God to the Daniel who lived in Babylon during the exile."7
