But the problem is that the moon's synodic orbit takes about 29.5 days to
get from one full moon to the next.  (It's sidereal period is a bit more 
than 27 days as I recall.)  The Hebrew calendar assumes the 28-day lunar
month and then has to jump through all sorts of hoops to keep the holidays
from getting completely out of whack.
