Thanks for your question.
There are some conflicting views about the exact age of Jesus at his death. However, I think that the answer is fairly straightforward. Luke 3:23 tells us that Jesus was about 30 years old at the start of his ministry. The Gospel records show us that the length of his ministry was about 3 years. Therefore, the Lord Jesus Christ would have been between 33 and 34 years old at the time of his death.
