When did King Tutankhamuns dad die?

Answer 1

King Tutankhamun's father was named Akhenaten (also spelled Akhenaton, Ikhnaton, Echnaton, or Khuenaten), and he is believed to have passed away in either 1336 or 1334 BC. We cannot be fully certain of his date of death, as the record is unclear during this period, but it is believed that his death occured in the 1330s BC.

Answer 2

King Tut's dad died before Tut himself reached the age of 9 (which was when he was married and became Pharaoh). So I am sure it is between the time between the age of 8-9. Tut was born in B.C.E 1343.
