I needed to read the Council rules for a quick bit of research. In doing so, I skimmed the definitions section, where I came across the definition of Council recess:

You will note that recess includes August through September 15…and, listed separately, July 15-August 1. So I ask, is there some substantive difference that requires the two periods to be identified separately, and not be written simply as “July 15th through September 15th”?
