... Remember that there are 309 lunar months in 25 calendar years of 365 days in the Carlsberg Papyrus (now at Manchester)....

Keith I have only just noticed that 309 could mean 309.017 and is 1000 times sine of 18 degrees. This coupled with the fact that the diameter of The Pyramid of Khafre at 411 cubits gives us a diagonal of 581.242 and if we use this as a diameter we get 1826.025 and is eqaul to 5 Earth Years at 365.20 days. So it is entirely conceivable that the entire structure was showing us not only Phi and Venus and it's pentagramal path as shown by the 5 and the pentagram, but was actually a calendar as well. Perhaps somewhere within all these measurements we might find an exact date of construction.

According to Wiki we have this ....

Synodic period = 29.530 589 d and according to me it should be multiplied by 1000 times the sine of 18 degrees or 309.017 and this gives us ... 9125.50 months and if we divide by our 25 years we get ... 365.02 and times 4 = 1460.08 To my mind this would appear to be the correct solution to these numbers
