I was looking for something and realised that except for one solitary Rupee (1119 / ahd) of this Ruler from the Ahmedabad mint, all other coins are missing on WoC. So here we go.
List of possible date combinations of Shah Alam Bahadur are mentioned below (thanks to the efforts of our mentor Jan Lingen (Oesho).
Accession date 24 Muharram, AH1119 = 16 April 1707. On the first of Shawwal 1119 (= 15 December 1707) Shah Alam Bahadur issued an order that his reign should commence from the 18th Zu l-hajja, 1118 = 12 March 1707, the day that he heard of his father’s death. Julian Dates. For the present (Gregorian) calendar add 11 days.
