All of the early dates seem to have the error.

That is a climatic/agricultural issue. If the barley is not ready, they insert the extra month. They must have Aviv barley for “First Fruits.”

That's good to know. Thank you.

I am very curious about breba figs near Passover time.

So the intercalary month makes the date come later seaonally? ad this drops back until another 2nd Adar is needed, I suppose?

I am confused, I had a (Jewish) instructor in college that was telling us that it had to do with the Jewish calender having 12 months of 29/30 days and that the extra month was inserted every 6 years. And then every 18 years they inserted and extra time period. He said it had to do with the flooding of the Nile. I don't recall all of the details and it has been 20+ years since I had Dr. Waxman.
