YaHavah provided a calendar to mark the time, boundaries, and circumstances of his son's first and second coming. It began at the end of Jerusalem's Babylonian captivity, but to know the biblical year it began, one must go back to the beginning in Adam's time. The Bible is about the history and purpose of YaHavah's his creation. The narration follows the lives of strategic people and events leading to the first and second coming of his only begotten human son. These are the circumstances. The calendar is the boundary of these circumstances. The calendar is linear; counting the years from Adam forward without any gaps in its timing of years. It progresses in two stages. The first is a chronology of people and events filtered through YaHavah's righteous line in Jesus' genealogy to Jerusalem's Babylonian captivity. The second stage is Daniel's seventy sevens prophecy to the end. This prophecy explains the circumstances and boundaries of YaHavah's end time prophecies.To avoid being caught in Satan's diversionary tactics; know with certainty that there is only one line of history of which we all must be fully aware. It is YaHavah's line of history in his calendar of Bible time fully reported within the pages of the Bible. This booklet is a condensed version of YaHavah's Bible calendar from Adam to the White Throne Judgment. It is about his appointed times and the boundaries of their circumstance from beginning to end.
