In Luke chapter 3, we read of the baptism of Jesus (NIV):
21 "When all the people were being baptized, Jesus was baptized too. And as he was praying, heaven was opened 22 and the Holy Spirit descended on him in bodily form like a dove. And a voice came from heaven: 'You are my Son, whom I love; with you I am well pleased.'
23 Now Jesus himself was about thirty years old when he began his ministry."
There is considerable evidence that Jesus was born on September 11, 3 B.C. (see http://www.believerlinks.com/cortright/revsign.htm). This date in history coincided with the New Moon, and an observance of the Festival of Trumpets (Tishri 1) in Jerusalem.
Per our prospective timeline for the Final Jubilee, the Second Coming would correspond with the Day of Atonement on September 11, 2027 A.D.. In other words, the Second Advent of Christ would occur on the anniversary of the First Advent of Christ, 2030 years later. Jesus was 30 years old when his ministry began, and it lasted three years. There are parallels here to the Body of Christ's three years of ministry between the Revelation 12 Sign of September 23, 2017, and the beginning of the Final Jubilee 3 years and 3 days later at sunset on September 26, 2020.
This Advent sequence also mirrors that of the Final Jubilee, which begins on an extended observance of the Festival of Trumpets, and concludes on the Day of Atonement (i.e. Jesus was born on Trumpets and returns on Atonement).
To link with the last post regarding Daniel chapter 8, we read in Genesis chapter 8 (NIV):
6 "After forty days Noah opened a window he had made in the ark 7 and sent out a raven, and it kept flying back and forth until the water had dried up from the earth. 8 Then he sent out a dove to see if the water had receded from the surface of the ground. 9 But the dove could find nowhere to perch because there was water over all the surface of the earth; so it returned to Noah in the ark. He reached out his hand and took the dove and brought it back to himself in the ark. 10 He waited seven more days and again sent out the dove from the ark. 11 When the dove returned to him in the evening, there in its beak was a freshly plucked olive leaf! Then Noah knew that the water had receded from the earth. 12 He waited seven more days and sent the dove out again, but this time it did not return to him."
This verse connects Jesus' baptism to his later prophecy of Matthew chapter 24 (NIV):
37 "As it was in the days of Noah, so it will be at the coming of the Son of Man. 38 For in the days before the flood, people were eating and drinking, marrying and giving in marriage, up to the day Noah entered the ark; 39 and they knew nothing about what would happen until the flood came and took them all away. That is how it will be at the coming of the Son of Man. 40 Two men will be in the field; one will be taken and the other left. 41 Two women will be grinding with a hand mill; one will be taken and the other left."
This seamless dovetailing of scripture with both past and future history testify to the perfect work of the Great Carpenter:
To Jesus Christ alone be the glory.
