The Book of Enoch is a forgery...
A forgery? I'm guessing you mean it wasn't written by Enoch? The right word for that is
pseudephigraphal. I don't think anyone on earth believes the Enoch of Genesis wrote any of the books...
Oh, yeah... the "Book of Enoch" is actually 5 different books, so which part are you referring to? Based on your comments, I'm guessing you're referring to the
the book of the courses of the luminaries of the heaven... which is one of the earlier sections, but also probably the least interesting. Also, it isn't the same part as the bit I referenced earlier in this thread.
Here's proof: It mentions a year of 365 1/4 days' length, same as the year is now, but in Enoch's time it was only 360 days long. And that's not due to the ancients' miscalculation. As all men of that time depended upon agriculture, knowing the correct length of the year was very-important to them. Had they been off by 5 1/4 days, their seasons woulda been off almost a whole month after only 5 years ! They knew the length of the year by observing the points of sunrises, sunsets, & the shadows found at dawn and sunset.
The year didn't attain its present length til the time of Hezekiah in the 700s BC.
Where are you getting this information? From what I know, the calendar in Enoch has 364 days.
