From Proto-Balto-Slavic *dein- (oblique stem *din-); compare Latvian dìena, Old Prussian deinan (acc. sg.), Proto-Slavic *dьnь. The ablaut in Balto-Slavic suggests an original Proto-Indo-European n-stem *déy-n- (genitive *din-és (“day”));^[1] compare Old Irish denus (“period of time”), Sanskrit मध्यन्दिन (madhyáṃdina-, “midday”), Latin nūndina (“market day”), Gothic 𐍃𐌹𐌽𐍄𐌴𐌹𐌽𐍃 (sinteins, “always, daily”). The root *dey- is also seen in diẽvas (“god”); see for more. Cognate with Samogitian dėina.
