The End of Days is the seventh and final volume of Zecharia Sitchin's Earth Chronicles, published in 2007 by William Morrow. The book opens with a structural question: why does the twenty-first century A.D. so closely resemble the twenty-first century B.C.? Sitchin's answer draws on the Anunnaki framework developed across the six preceding volumes: a celestial time cycle, governed by the 3,600-year orbit of Nibiru, that drives a deterministic recurrence of earthly events. He reads biblical prophecy — particularly from Daniel, Revelation, and the Pseudepigrapha — alongside Sumerian cuneiform records, arguing that the Anunnaki schedule of departure and return maps directly onto the messianic expectations embedded in the Hebrew Bible and in early Christianity.
The book's sixteen chapters trace the development of messianic expectation from Sumerian and Egyptian texts through the Hebrew prophets and into the New Testament, culminating in Sitchin's reading of Armageddon as a literal astronomical event tied to the return of Nibiru. Reception in the ancient-astronaut genre regarded it as the series' most overtly prophetic volume; readers familiar with the earlier books found significant overlap with material from the prior six entries. Scholars of biblical studies, Sumerology, and astronomy do not accept Sitchin's interpretive framework.

Reception
The seventh and concluding Earth Chronicles volume, and the most explicitly prophetic. Readers within the ancient-astronaut genre found it brought the series to a coherent close, tying Anunnaki cosmology to biblical messianic expectation and the Armageddon scenario; several noted substantial overlap with arguments from earlier volumes. Sitchin's correlation of the 3,600-year Nibiru cycle with the prophetic timetables of Daniel, Revelation, and the Pseudepigrapha generated the most discussion. His interpretation of Armageddon as the valley of Megiddo in Israel — site of the Anunnaki return — was widely cited in 2012-era apocalyptic literature. Scholars of biblical studies, Sumerology, ancient Near Eastern religion, and astronomy reject his interpretive framework.
Frequently asked
What is The End of Days about?
It is Zecharia Sitchin's seventh and final Earth Chronicles volume, published in 2007. Drawing on the Anunnaki framework from the six preceding books, it reads biblical prophecy — in Daniel, Revelation, and the Pseudepigrapha — alongside Sumerian cuneiform records, arguing that the 3,600-year Nibiru cycle and the messianic expectation of the Hebrew Bible describe the same deterministic celestial schedule.
How does it connect to the rest of the Earth Chronicles series?
It is the concluding volume of seven, synthesising the Anunnaki cosmology from all prior books into an explicitly prophetic statement. Sitchin correlates the Anunnaki departure from Earth with events in the first-millennium B.C. Hebrew prophets, then projects the cycle forward to interpret contemporary geopolitics as a prelude to their return. Scholars of Sumerology and biblical studies do not accept his framework.
What is Armageddon in Sitchin's reading?
Sitchin reads Armageddon not as a purely symbolic event but as the valley of Megiddo in Israel — the site, in his argument, at which the returning Anunnaki and human forces will converge. He correlates this with the 3,600-year orbit of Nibiru and with prophetic timetables in Daniel and Revelation, treating all three as descriptions of a single astronomical event from different cultural vantage points.
