When was Saul of Tarsus born?

The Bible doesn't say exactly, but we can make an educated guess if we look at the years he was preaching.

He began his first missionary tour around 47-48 CE, and his third around 52-56 CE. He was imprisoned for the second time in Rome around 65 CE , where he wrote his second letter to Timothy, implying that his death was imminent (2Timothy 4:6-8), and was most likely martyred by Emperor Nero soon after.
