This “hemerological compilation” consists of a series of calendrical divination texts. According to its rubric, the tablet lists “favorable days for the entire year, consisting of 15 mont[hs (…), that is, 12 months] with 3 intercalary months” (ix 22-23). The rubric is followed by a colophon in which the scribe identifies himself as Nab[û/Bē[l-…, a Babylonian apprentice and a member of the Iddin-Marduk family. Although this family was active in both Babylon and Sippar, the present tablet ostensibly comes from the latter city, since the colophon mentions that it was deposited in the Ebabbar.
The greatest part of the tablet, which spans columns i-viii, is an excerpt from the menological series Iqqur īpuš, to which some short explanations are appended. These exact same explanations are found in other hemerological compilations that quote from Iqqur īpuš: for instance, in MLC 2627 (CCP 3.8.1.B), from Late Babylonian Uruk, and in K.98+ (CCP 3.8.1.A), written by the Assyrian scholar Nabû-zuqup-kēnu, who lived in the 8th and 7th centuries.
These three tablets are hemerological compilations of the same type: the commented section of the general series of Iqqur īpuš is combined with a list of lucky days. In addition, the present tablet provides some general rules for calendrical divination, such as the list of days that, in any given month, are favorable for carrying out an activity (ix 17-21). These rules are probably inferred from the Iqqur īpuš excerpts that precede them.
