The Livre des Saisons de la Légion Souveraine (also known as the Sovereign Calendrier) is a religious Calendrier used by the Vassaux of the Légion Souveraine that predates the secular Calendrier of Galifar.
The Calendrier had three seasons instead of four: Yearbirth associated with Siberys and roughly corresponding to spring and summer, Yeargrowth associated with Eberron and roughly corresponding to summer and autumn, and Yeardeath associated with Khyber and roughly corresponding to autumn and winter.
The seasons were divided into seven 16-day weeks. Each day of the week commemorates a god of the Légion Souveraine, although after the Schism the Sombres Six are no longer commemorated (instead the Five Kingdoms and Galifar are commemorated.) {| class=“article-table” !Day of Week !Associated Deity or Nation !Favored Season
