Date: A.D. 63-66
It seems clear by comparing Acts with the epistles that 1 Timothy and Titus belong to the period after Paul’s first release and acquittal in Rome. Because of this, 1 Timothy must be dated after his first release, around the spring of A.D. 63, but before the outbreak of the Neronian persecutions in A.D. 64. First Timothy was probably written in A.D. 63 right after his first release. Titus was written around A.D. 65 and 2 Timothy in A.D. 66. Paul died in A.D. 67, according to the early church father, Eusebius. As a Roman citizen, he died by the sword (beheaded) rather than by crucifixion as did Peter.

Paul’s missionary journeys occupied approximately the years A.D. 48-56. From 56-60 Paul was slowly making his way through the Roman courts, arriving ultimately at Rome. For two years, 61-62, Paul was held under house arrest in Rome, at the end of which time, it can be surmised, he was released. From 62-67 Paul traveled more or less freely, leaving Timothy in Ephesus and Titus in Crete, and then subsequently writing each of them a letter. Thus the approximate dates for 1 Timothy and Titus are perhaps 63-66. After being recaptured and once again imprisoned, Paul wrote Timothy a second letter, 2 Timothy. Thus 2 Timothy, dated approximately A.D. 67, represents the last Pauline Epistle
