سنوسرت الثاني
At present, the problem concerning the reign length of Senusret II is irresolvable but many Egyptologists today prefer to assign him a reign of 9 or 10 years only given the absence of higher dates attested for him beyond his 8th regnal year. This would entail amending the 19-year figure which the Turin Canon assigns for a 12th dynasty ruler in his position to 9 years instead. However, Senusret II's monthly figure on the throne might be ascertained. According to Jürgen von Beckerath, the temple documents of El-Lahun, the pyramid city of Sesostris/Senusret II often mention the Festival of "Going Forth to Heaven" which might be the date of death for this ruler. These documents state that this Festival occurred on IV Peret day 14.
