BCE dates off by 1 year due to zero year error

[Ken Wade]

Perhaps I don't have the latest version? I am using Stellarium 0.13.3 on a MacBook Pro.
In referencing dates BCE, I find that the sky conditions are off by one year because the program includes a zero year. In other words, the position of the moon in Stellarium year 585 BC actually reflects the conditions in 586 BC.
This was determined by referring to comprehensive data that has been collected by chronologists re: the time of the fall of Jerusalem to the Babylonian army.
In checking the program, I noted that if you go back 1 year from 1 C. E. it gives you the year zero, thus throwing everything prior to that off by one year since the Julian and Gregorian calendars have no year zero.

Thanks for the clarification! I’ll adjust my usage of the program accordingly. It’s a great program!
