The Sacred Calendar in accordance with the instructions given to Enoch, father of Methuselah, and great grandfather of Noah. The Messenger Uriel revealed the instructions to Enoch. The Calendar is unique in that it contains the evidence of the changes to the earth as a result of Noah's flood. This Calendar was restored to the people of Israel during the Exodus. The Enoch Calendar was followed until shortly after the Temple was destroyed in 70 AD. Its structure is 364 days divided into four quarters of 91 days. Each quarter starts in the middle of the Enoch week, which is the fourth day of the Enoch week. Enoch's vision of the "Weeks" defines the seven ages of the "Day of Man." Periods of seven days and seven weeks are shown throughout the Enoch Year as part of the Sabbaths, Feasts and High Days given to the people of Israel during the Exodus. All of prophetic numbers of the Prophet Daniel and the Apostle John are directly tied to the Enoch year. Only 360 days of each year are included in the count of the prophecies. The last days of each quarter is not counted. The earth's rotation was increased because of the flood, and the earth's orbit changed resulting in an increase in number of days in the solar year. The Enoch year starts immediately after the vernal equinox. Because there are more days in the solar year than in the Enoch year, the extra day number 365 or the leap day number 366 must be added to the end of the Enoch year as uncounted days. The Enoch year was prophesied to continue until the "New Heavens and New Earth" are established.
