Re: Jewish myth - 28 year cycle?

According to the Wikipedia article, the number of days in the 19-year solar cycle is the same as the number of days in this particular 19-year lunar cycle. That's all I know...but holidays still fall at more or less the same times of the year, within about a 1-month range.

our yearly jaunt around the sun does not align exactly along our 24
