The calendar starts from April 3rd, 47 BC, when, according to Catameilan teachings, Sattama left this world/universe to save others. In Sonnend language, dates after this are written as 'MD' (Manja Daremmusy, After finishing the job), and dates before 0 are written as 'EEE' (Ema ela erkiji, Before anything in our minds)
