Hi,

I've never heard of that word in English. Do you mean Almanac?

An almanac (also spelled almanack) is an annual publication containing tabular information in a particular field or fields often arranged according to the calendar.

The Encyclopædia Britannica says that it is of uncertain medieval Arabic origin, comparing it to the modern Arabic word for weather, المناخ al-manaakh. Other dictionaries have it from the Greek almenikhiaka for ephemeris, via the Medieval Latin almanach and the Middle English almenak.

Richard Verstegan in his A Restitution of Decayed Intelligence (1605) says that the word originates in the Old Saxon Al-mon-aght, which he translates as "Al-mon-heed, to wit, the regard or observation of all the moons".
