Second Coming
The Second Coming (sometimes called the Second Advent or the Parousia) is a Christian and Islamic belief regarding the future (or past) return of Jesus Christ after his ascension to heaven about two thousand years ago. The idea is based on messianic prophecies and is part of most Christian eschatologies.
Chronology of Jesus
The date of birth of Jesus of Nazareth is not stated in the gospels or in any secular text, but most scholars assume a date of birth between 6 BC and 4 BC. Two main methods have been used to estimate the year of the birth of Jesus: one based on the accounts of his birth in the gospels with reference to King Herod's reign, and another based on subtracting his stated age of "about 30 years" from the time when he began preaching () in "the fifteenth year of the reign of Tiberius Caesar" (): the two methods indicate a date of birth before Herod's death in 4 BC, and a date of birth around 2 BC, respectively.
