                                      ^^^^^^^^^

AFAI understand it, this will put *everything* before $DAYSAGO into the
zip file for each of the days between $STARTDATE and $FIRSTZIPDATE which
*doesn't* appear to be what you want.  Assuming you want a single zip file
per day containing *only* that day's files you should use 

"-mtime $DAYSAGO"

in the line above.
