Unfortunately, the birth and death dates for St. Patrick are unknown. There are two writings from him that exist, but they do not list a date; however, the style of those letters (Letters to the Soldiers of Coroticus and Confessio) suggest the fifth century. Scholars believe that his death occurred in the later fifth century, but it appears that there may have been another Patrick who worked in Ireland around the same time and the dates between the two Patricks may have become tangled. This other Patrick—called the elder Patrick, Sen Patraic, Old Patrick, and similar names—is thought by some scholars to be the same person as Palladius. According to this theory, the elder Patrick died around 457 or 461. Based on newer interpretations of Irish annals, the second Patrick (the one who is celebrated on St. Patrick’s Day) is thought to have died around 493. Hope this helps!
