I don't know the day and hour of the rapture (this is definitely not given in the bible), but it's 70 years from the HC year of 5708. And Christ's literal return on earth is 7 years after. It's in the bible (lot of scriptures in the old testament), plus the season and signs not mentioned in the bible also points to that year. One notable sign was the Star of Bethlehem which arrived last year, June 2015, and will again a second time in the year 2023.
The Star of Bethlehem was seen twice in 3BC and 2BC.
Sky & Telescope Contributing Editor Fred Schaaf points out that this current string of Venus-Jupiter conjunctions closely resembles a similar series between the years 3 and 2 B.C. It has been suggested that their joint appearance came to be known as the Star of Bethlehem.

The only New Testament account of the Star of Bethlehem occurs in the Gospel of Matthew, where the magi arrive in Jerusalem during the reign of Herod the Great, asking about a newborn king of the Jews, having seen "the rising of his star."
In a 1991 article in The Planetarian journal, William Bidelman, former chairman of the astronomy department at Case Western Reserve University, put forth two conjunctions of Venus and Jupiter in 3 B.C. and 2 B.C. as the most plausible Christmas star.
In the October 1991 Omni magazine, astronomer Fred Schaff also pointed to the rare series of Venus and Jupiter conjunctions on Aug. 12, 3 B.C.; and June 17, Aug. 20 and Oct. 14 in 2 B.C.

After roughly 2000 years, the Star of Bethlehem appeared again on June 2015 and will appear a second time eight years later in 2023.
Those expecting a Pre-Tribulation rapture will be please to know the correlation between the star of bethlehem appearing in
3BC and
2 BC, and again last year;
3 years before the start of the tribulation (Yes! It's in the bible!) and again in 2023;
2 years before Christ literally returns to earth. By now you should be able to figure out the year of divine peace prophecies for Israel falls on 5778 HC. Abraham was also born in the HC year of 1948. God came to Abraham and made a covenant with him in the HC year of 2018 when he was age 70 and told him he would someday become a great nation. He left Haran at age 75. Well the Jewish people and Israel has never been a great nation. In fact, it's looked more like a conquered nation and people. During its long history, the city of Jerusalem has been destroyed twice, besieged 23 times, attacked 52 times, and captured and recaptured 44 times.

But the bible mentions that Jerusalem and Israel will finally become a great nation during the first year of the tribulation after God turns His attention away from the gentiles and back to the Jewish people and bless them during the first half of the tribulation while the rest of the world is being judged. Zechariah 1:16-2:13. This is also in other prophetic scriptures but I'm too lazy to dig them up right now.
