You are in big trouble with your claims about VAT 4956 which conflicts with the research by Dr. Rolf Furuli and that of the 'celebrated WT scholars who have proved that Neb's 37th year mentioned in the tablet was in 588 BCE and not 568 BCE as a far better fit using the astronomical data available.
To show the complexity of trying to interpret the lunar and planetary data into a modern calendar system perhaps you should examine the website VAT 4956.com
