Martorian Calendar

The Martorian Calendar is the official calendar of the Serene Duchy of Martoria and the most commonly-used system of dating among the continental Ga'elevae.
The Martorian Calendar is dated from the year of the Ga'elevae's arrival on Cerulea, counting the years from the start of their arrival with Ala Cerulea (A.C.) while Nó Cerulea (N.C.) denotes the years before.
