This reference to the defeat of Setnakhte's enemies implies that this specific date marked the termination of a conflict—presumably Setnakhte's struggle for the throne—which extended partly into his second year and means that Setnakhte's first year would have overlapped with Twosret's final year, if Twosret was his opponent. Therefore, he likely did not even rule Egypt in his theoretical first year and could only properly administer the country from sometime during his second year. In any event, there was an interregnum lasting at least a year in which no ruler controlled all of Egypt and Setnakhte's effective reign length should be reduced by a year from 4 to 3 years.
