Hi Sam,
No problem, alot of people get confused by all the holidays. To add to the confusion, the dates change every year because they are scheduled according to a lunar and seasonal calender rather than the solar calender that most people are used to. Just remember, we didn't make them, we just follow them. The days between Rosh Hoshanna and Yom Kippur are the days of judgement that most people read about in the Book of Revelation - where the books are opened and all mankind is judged. Few realize that this is the time of the year that this is done, and even fewer realize that this is a yearly event. As for the timing, well you'll just have to ask The Big Course Director Upstairs - s/he's totally in charge of setting the dates.
Take care, and Happy New Year!
George
