Anka year

Anka year (Odia: ଅଙ୍କ Aṅka) system is a unique regnal year system used in the state of Odisha, India and was instituted by the rulers of the Eastern Ganga dynasty for dating their reigns. It had a number of features that mark the regnal year different from that actual duration of the year elapsed during the reign. The system still survives today and is used in the Odia calendar (panji) to mark the titular regnal year of the Gajapati Maharaja (King of Puri) which is currently held by Divyasingha Deva IV of the Bhoi dynasty, whose title carries the legacy of the historical ruling monarchs of Odisha.
