The months of the year in Pontus were named after certain farming conditions as well as Holy days on the calendar. July was called Χορτοθέρ'τς (Xortotherts) because in July each year they collected grass. November was called Αεργίτες, named after Ayios Georgios because the 3rd of November was the Holy day of Άγιος Γεώργιος.
