Early applicants (June) received interviews as soon as September- OCtober! Check out the STATS pAGe thread. Some sdner's posted the dates of their interview.
Just some advice. Schedule interviews wisely! Don't waste your time applying or interviewing far away where you are not committed to move. Schedule priority schools sooner than secondary schools. (i.e. schedule your top schools ASAP, SChedule scondary schools after December, the general notification of acceptance date)

I know temple's first interview date was towards the end sept, it was a week or two after 9-11 happened...(remember flying out the second day the airports were up and running again....)
