The Aldurian Calendar was invented under the reign of Al'Dur Kharata; the first Emperor of the Eloysian Empire of Azoria.
Al'Dur was an extremely proud man; he declared the creation of his Empire as the "Dawn of a New Age," and created his own Calendar, calling it the "Year Zero." To this day, the Aldurian Calendar is still used on Azoria, and the founding of the Empire is known as Year: AR 001.
