Calendar dates in Jubilees’ Garden of Eden story have led some to question the nature of the book’s presupposed calendar and others to conclude that the passage is redacted. Close reading of the text shows that the passage was carefully constructed and the work of one author who took pains not to jeopardize the calendar promoted elsewhere in the book. Confusion arises when scholars subordinate the calendar to the book’s chronological system; they should be kept distinct. The author uses the recurrence of calendar dates to connect events to each other typologically and to an underlying narrative pattern, which, like the calendar, is founded on the annual cycle of agricultural labor.
