Middle English almenak, from Medieval Latin almanach, perhaps from Late Greek almenikhiaka, ephemeris, perhaps of Coptic origin.(American Heritage® Dictionary of the English Language, Fourth Edition)
Old French almanach, from Medieval Latin almanachus, from Andalusian Arabic (almanak, "almanac, calendar") > or, from Arabic المناخ (al-manāx, "climate"), from Late Ancient Greek ἀλμενιχιακά ("calendar"), probably ultimately of Coptic origin. Possibly the central syllable -man- is cognate with moon and month, or else was influenced by Proto-Indo-European *mens- (“moon, month”), from Proto-Indo-European base *me- (to measure). (Wiktionary)
