The grants are dated in the regnal years of the ruling king. The date is mentioned in form of the regal year, followed by the month and then the day. The days are numbered 1–30, and there is no mention of a fortnight. It is not clear if the month starts from the full moon day (purnimanta) or from the new moon day (amanta). The Panduvamshis, who succeeded the Sharabhapuriyas and adopted their style of inscriptions, followed the purnimanta system. Therefore, it is very likely that the months mentioned in the Sharabhapuriya inscriptions also followed the purnimanta system.
