The identification of KBo 58.175 as an outline tablet of the nuntarriyašḫa- festival remains tentative, as the text shows no clear overlap with any other outline. However, several indications speak in favour of this attribution. First, the text is clearly an outline tablet with a day number assigned to each paragraph. Second, it mentions a ḫadauri- festival and a ḫapalzil/r- vessel, terms attested in the celebrations of Ziparwa within the nuntarriyašḫa- festival. Third, lines 2′f. include a day number followed by a paragraph line and a sentence ending with ]-a pa-iz-zi, a sequence found exclusively in the ‘Ziparwa-days’ as described in the AN.DAḪ.ŠUM and the nuntarriyašḫa- outline tablets. Taken together, although still circumstantial, these elements suggest that the text corresponds to DAYS 7–9 or DAYS 8–10 of the nuntarriyašḫa- festival.

The fragment likely preserves the lower part of col. i.

Although the evidence is limited, Outline.16 seems to have been written in the New Script.
