"Farmers Almanac, 1978" (should it be Farmers' Almanac?) belongs in the comment box and is not part of the sentence.
This applies to all translations.
I'm not an expert, but I think that even if the sentence has copyright protection, this is fair use quotation, because this site aim is "nonprofit educational purposes".

(I linked to the U.S. fair use section because the sentence is from 'Farmers Almanac', a U.S. publication)
