Long ago removed from the Bible, this book, among other things, describes an ancient calendar which, unsurprisingly, has come to be known as the Enoch calendar. This ancient Enoch calendar, while it may seem similar on the surface, differs from our modern Gregorian calendar in a significant and affecting way. This book contains the astronomical knowledge as it was given to Enoch by the archangel Uriel, during Enoch's trips through Heaven. In addition to the calendar itself, Uriel bestows upon Enoch information relating to laws by which the sun, moon, stars, and winds are governed as well as other mysteries of the Universe.
