This volume presents the biblical concepts of time. The various ages of time and Jewish eschatology are examined. Questions concerning how many Biblical calendars are valid are addressed. From a Biblical framework evidence is presented to show that both the Civil and Religious Calendars were used and that this understanding is crucial to deciphering eschatology. In addition to the Calendars, the Festivals are discussed and how they relate to both the first and second comings of the Messiah. While many are familiar with much of this material, an examination of the Seasons such as Teshuvah, Yamin Noraim and others will add a needed piece of the eschatological puzzle.
