Joseph's exact age when he married Mary is not stated in the Bible. However, based on historical and cultural context in 1st century Israel, scholars generally estimate that Joseph was likely a young man in his late teens or early twenties at the time of marriage. This estimation is supported by the fact that men typically completed apprenticeships by that age and were expected to be able to support a family. The Bible does not give a precise age for Joseph, and some traditions that claim much older ages, such as Joseph being 90 years old at marriage, are not biblically supported or credible since Joseph fathered other children after Jesus. The Gospels emphasize Joseph's righteousness and faithful character rather than his age. In sum, Joseph was likely a young adult, possibly around 18 to 25 years old, when he married Mary, who was likely in her early teens, according to common customs of the time.
