How old was Jesus when He died?
Short answer: 33 years old
“It is usually accepted by theologians that Jesus was in his early thirties when he was crucified and resurrected. A rough number can be 33 when he died.” - Answers.com
“No one knows exactly how old Jesus was when he died on the cross, but he was probably 33 years of age. This is drawn from two main things. First, Jesus was baptized to enter into the Melchizedek priesthood. In Matthew 3:13-15 it says, “Then Jesus came from Galilee to the Jordan to be baptized by John. But John tried to deter him, saying, “I need to be baptized by you, and do you come to me?’ Jesus replied, ‘Let it be so now; it is proper for us to do this to fulfill all righteousness.’” Jesus got baptized to fulfill all righteousness. This fulfillment was in reference to the Old Testament requirements for being a priest, which among them was being the minimum age of 30. “from thirty years and upward, even to fifty years old, all who enter the service to do the work in the tent of meeting,” (Num. 4:3)…Second, most Christian scholars agree that Jesus’ ministry lasted 3 1/2 years. So, 30+ 3 1/2 equals the age of 33.” - CARM
“This is a subject that has been debated by scholars for many years. There are no passages that give the exact time historically speaking other than general historical references that have to be determined from what we know of the history of the time, like when Herod ruled and the historical references in Luke 2:1f. See also Luke 3:23 andJohn 8:57. The general consensus is that He was in His mid thirties.” - Bible.org
