An Etymological Dictionary of the German Language/Annotated/Almanach
Almanach, masculine ‘almanac,’ first appears in early Modern High German, from French almanack, which with its Romance cognates is said to have come from Arabic through Spanish, like other words beginning with Al- (see Alchimie, Alkoven). But as the Arabic word for calendar is certainly not Almanach, but taquîm (Milanese taccuino), the derivation from Greek-Egyptian ἀλμενιχιακά, ‘calendar’ (found in the Eccl. Hist. of Eusebius), is much more likely to be correct.
