When the angel came again to tell him that his family was in danger, he immediately left everything he owned, all his family and friends, and fled to a strange country with his young wife and the baby. He waited in Egypt without question until the angel told him it was safe to go back (Matthew 2:13-23).
Since Joseph does not appear in Jesus' public life, at his death, or resurrection, many historians believe Joseph probably had died before Jesus entered public ministry.
According to the Catholic Encyclopedia, the Apocryphal Date for Joseph's birth is 90 BC in Bethlehem and the Apocryphal Date of his death is July 20, AD 18 in Nazareth.
Joseph is the patron saint of the dying because, assuming he died before Jesus' public life, he died with Jesus and Mary close to him, the way we all would like to leave this earth.
Joseph is also patron saint of the Universal Church, families, fathers, expectant mothers (pregnant women), travelers, immigrants, house sellers and buyers, craftsmen, engineers, and working people in general.
We celebrate two feast days for Joseph: March 19 for Joseph the Husband of Mary and May 1 for Joseph the Worker. March 19 has been the most commonly celebrated feast day for Joseph, and it wasn't until 1955 that Pope Pius XII established the Feast of "St. Joseph the Worker" to be celebrated on May 1. This is also May Day (International Workers' Day) and believed to reflect Joseph's status as the patron of workers.
Many places and churches all over the world are named after St. Joseph, including the Spanish form, San Jose, which is the most commonly named place in the world. Joseph is considered by many to also be the patron saint of the New World; of the countries China, Canada, Korea, Mexico, Austria, Belgium, Croatia, Peru, Vietnam; of the regions Carinthia, Styria, Tyrol, Sicily; and of several main cities and dioceses
