"It sounds about right... though if one bases a year on a true Solar orbital circuit and not just the lunar cycles, it's liable to be off by quite a bit by now. I take it the Hebrew calendar doesn't correct for anything outside of a strict lunar cycle, yes?"

d Actually the Hebrew calender is both a lunar and a solar calender rolled into one.  Its months are divided up using the lunar cycles as a means of demarcation, each new moon indicates the beginning of a new month, but every few years, an extra month of Adar (which is always in late Winter) is added before the month of Nisan (which marks the beginning of Spring). ** This is important because Passover is on the 15th of Nisan, and must always occur at the beginning of Spring.
