These are only 2 week guidelines. If the 9/15 to 9/30 is the most popular date and then 9/1 to 9/15 is second then we probably combine those dates to come somewhere in the middle to make as many people as possible happy.
Good thing to post if ANY dates are a NO GO for someone such as these holidays. Should be easy to adjust the primary choice dates to accommodate a few issues like this.
