Steve, Some people actually do seem to follow a lunar year, like the Muslims, with their Ramadan. However, didn't Israel still only have one Passover, every full year? Passover never happens in the fall, does it? Isn't a lunar calendar based on something close to 355 days in a lunar year? If Israel only had a lunar calendar, then wouldn't they have ended up having an "extra" Passover every so often? But that didn't happen, did it? I thought that they remedied this by periodic calendar adjustment? Even the solar calendar is adjusted, too, but that is on a four year period, adding an extra day to February. Am I way off base? Or did Israel only have a lunar calendar without adjustment?
