This is the legend about the history of the Jubilee calendar as pieced together from many sources over decades.
The book of Enoch gives the origin of the Jubilee calendar, starting from when Enoch, Noah’s great-grandfather Enoch was taken to the moon and shown how our solar system works, calling degrees of movement a “gate” and other technical terms by names more familiar to humans. Enoch wrote it al down and placed it in an archive which he passed down to the successors to his neawly-created position as “king of the world and friend of the [lesser] gods”, who had teraformed this world after the bath it got during its dislodgement from Jupiter, along with Mars, as satellites resulting in the conditions described in Genesis 1:1. Enoch was also given two forms of writing, one ceremonial style that took a long time to write, and another that we would describe as shorthand today, that was much faster to write.
Noah and his grandfather, Methuselah, spent 120 years among the Igigi, the group of 50 Watchers, who had rebelled by leaving their post on Mars and come to earth to take wives from among human women so they could get children, which was forbidden to them. There are three races: humans made from red clay; messengers [angels], some made from fire and some from ice; and two God beings made from light, the one greater light being the original, and the lesser light having come from the greater in the form of a spoken word. The greater being of light is the Creator of all matter through the agency of the lesser being. It was this greater being of light that gave the command that the three races should not inter-breed, as it would not be a compatible mixture. When the Igigi broke this command, at first everything looked like it was “as usual”, but when the flood of Noah’s days came, the “confusion” that resulted showed up. The human [clay] half drowned in the water, leaving the fire/ice half without a body, making it impossible for the being to do anything tangible unless they could use an existing body as an agency. We call these spirits “demons” today.
But back to the calendar.
The job of “King of the world” was designed to relieve the lesser gods – called that because they don’t die a natural death – of the day-to-day annoyance associated with the noise of larger settlements of humans, the problems of housing, water, and sewage, and the fact that humans, being a hibredf between an earth animal and the lesser gods, have the common trait of such beings as trying to use both their earth brain and their fire brain at the same time, making them cranky, difficult to be around, and have a generally negative attitude with matching actions.
The human males had ruled their immediate families in the manner of a tribe from the beginning, but this change put one person over everyone on earth, which generally made the kings rebellious, mean-spirited, and selfish, a mirror that allows us all to see others as they see us.
We are now down to the part of the legend where Noah took the seed of all living things into the ark with him. [He could have left the mosquitoes and snakes outside and saved himself a lot of complaints.]
He also took the library of his kingship on board the ark with him, along with the bodies of Adam and Eve.
Now fast-forward 10 generations. [Data is missing for this time period]
The first-born of the first-born for nine generations has passed, and the tile of king is being carried by Terah, who is serving the half-god Nimrod [Gilgamesh] as his chief prince and military commander, the same pattern and position as his fathers, when Nimrod decides to open a business.
Nimrod had Terah make 12 large statues and 360 small ones. He had a one-room house built with 12 windows. He associated each of the large statues with a window and placed 30 of the small statues in front of each of the 12 large statues, dressed them all in fine clothing, and opened the house to the public as a temple where they were to worship these statues, introducing idolatry into the world. His business was to sell replicas of these statues to the public, and Terah was the designated seller, but Terah had his own problems.
Terah had two sons by his first wife, then she died. One of the presents brought to Nimrod by his local representatives and tax collectors was a daughter designated as a wife for Terah, who accepted her. She bore Abraham to Terah when his other two sons were 30 and 32 years old respectively.
It was the custom in those days for the astronomers who were also astrologers to attend the birth of any child that might have an impact on the king’s power. They reported back to Nimrod that Abraham was a major danger to the king’s life, so Terah hid him in a cave for the first 10 years of his life, then at the academy with Shem, where he underwent the training as a king, which – in Abraham’s case – included the knowledge and trade in precious gem stones.
When Abraham was 49 years old, he returned to Terah’s home, complete with full beard to mark him as a married man that obscured his real identity and a wife, Susanna, named for the country of her birth northeast of Ur, and children. Terah made him the commander of a quick-strike camel team consisting of 300 fighting men, 12 team leaders, 4 Sergeants, Eliezar as the general, and Ino as scribe. Eliezar was the king of Damascus and also a son of Nimrod by a human mother, as was Ino, who were given to Abraham as slaves, and probably also spies to make sure Abraham stayed loyal to Nimrod.
It didn’t take long for Abraham to get into trouble. He was so upset by the idolatry business that he snuck out in the middle of the night and set fire to the building, thinking that no one would know who did it. By the time the fire was discovered, the building was fully engulfed, and when Haran rushed in to save the idols, the roof caved in on him and killed him. Abraham ended up fleeing for his life back to Noah. Terah resigned his position in Nimrod’s court and moved to the city of Haran in the north-west corner of Nimrod’s kingdom, a trading hub between Turkey and Egypt. Susanna and her children are never heard from again, but the lament of Abraham, saying, “What will you give me, seeing I have no children?” tells of their demise there.
Sarah was made barren according to the practice of the times, so traveled with the camp, now holding more than an estimated 700 persons, counting fighting men, their families, herdsmen, and other support personnel. It was during this time that Abraham was sent to protect what is now a black spot on today’s map of Israel, which is rumored to have been a lesser-god stronghold.
Marduk was raiding the northern territory and threatening to penetrate down into that area. It was around this time that Chedolamer defeated Nimrod, and the people began calling Nimrod “Amraphel”. That defeat left Abraham without a job and a paycheck, so he became a herder of camels, donkeys, sheep and goats, as well as a commercial trader in gem stones. He also trained all his camp in trading and the manufacture of goods popular in the trading centers. This was the embryo that became the Phoenicians.
The persons in Abraham’s camp were from many places, but mostly from Syria and the local area, which was inhabited by Philistines who had settled the coastal areas as early as 3,000 BCE and built an active trade with Egypt.
Move on down the timeline to the days when Jacob was in the pastures of Aram, getting wives and flocks of his own. Abraham had died when Jacob was 15 years old, and Jacob had bought the birthright from Esau, resulting in Jacob going to the Academy for kings with Shem for his 40 years of training, which he completed when he was 60, just before his journey to Laban.
Jacob had been in Syria with Laban for at least 15 years when Esau and his sons raided the camp of Isaac, who was blind and bed-ridden, taken all the cattle, and burned all their dwellings. This left well over 1,000 people without food, clothing or shelter. Their response was to migrate to their brothers on the sea-coast and join their fishing and trading businesses. This created two distinct groups of Philistines, the uncircumcised ones, and those who had been circumcised during the covenant with Abraham. They were the same bloodlines, but entirely different cultures. The servants of Abraham taught the traders all the skills of handicrafts, and the traders taught the servant of Abraham the sea routes and trading practices. The traders who accepted the servants of Abraham into their lives were the first to call them “Phoenix” because they had risen from the fires of Esau into a new life on the sea.
It was these servants of Abraham who taught the traders the calendar, the alphabet, many of the manufacture techniques that they had learned from Abraham while he was associated with the Euphrates River cultures. The calendar was so essential to their sailing according to the weather, that they refused to abandon it when the entire area was captured by the first Babylon, choosing to convert all of their knowledge to trade secrets instead, the revealing of which was dealt with through death, but death was a two-way street. If the traders didn’t use the Babylonian moon calendar in trade with their land bases, the Babylonians executed them. They responded to the situation by becoming proficient in the use of both calendars, the Jubilee calendar for travel, and the moon calendar for land bases.
The height of the Phoenician trade occurred during the reigns of Kings David and Solomon, then diminished as the drought set in and choked the land and sea trade alike, finally weakened beyond recovery after losing Carthage and retreating to Portugal, where the saying goes: “Portugal is their cradle, the world is their grave”. It was finally the English mastery of the sea that caused Portugal to lose its power and control over sea trade, and that only in recent history.
The Phoenix has returned to its nest, waiting its next resurrection in Tyre.
 Ancient sources are seldom specific about how many generations have passed since a certain incident occurred, so this is a best-guess estimate.
