rather than storing the entire nine months logs in one file, have you considered one file for each month? then it would be trivial to move each month "up" at month end:
<top of head mod>
which will move each file "up" by one each time it is run, knocking the last file off the end (actually overwriting it with the months before).
does this help?

NAME
arbitron - arbitron mailboxes
SYNOPSIS
arbitron [ -C config-file ] [ -o ] [ -u ] [ -l ] [ -p months ]
[ -d days | -D mmddyyyy[:mmddyyyy] ] mailbox...
DESCRIPTION
Arbitron collects and reports readership statistics for mailboxes on the server. It also optionally prunes the mailboxes of Seen state
for dormant users.
Arbitron produces one line of output per mailbox, reporting the mailbox name followed by a space, followed by the number of readers (and if
-u is specified, followed by a colon and a comma-separated list of the readers userids), and if -o is not specified, another space and the
number of subscribers (and if -u is specified, followed by a colon and a comma-separated list of the subscribers userids). IMPORTANT: This
format is subject to change in future versions.
Each "reader" is a distinct authentication identity which has "s" rights to the mailbox and which has SELECTed the mailbox within either
the past days days or the specified date range. Users are not counted as reading their own personal mailboxes. Personal mailboxes are not
reported unless there is at least one reader other than the mailboxes owner.
Arbitron reads its configuration options out of the imapd.conf(5) file unless specified otherwise by -C.
OPTIONS -C config-file
Read configuration options from config-file.
-o "old way" -- do not report subscribers.
-u Report userids in addition to the count(s).
-l Enable long reporting (comma delimited table consisting of mbox, userid, r/s, start time, end time).
-d days
Count as a reader an authentication identity which has SELECTed the mailbox within days days. Default is 30.
-D mmddyyyy[:mmddyyyy]
Count as a reader an authentication identity which has SELECTed the mailbox within the given date range. The start date and
optional end date are specified as 2-digit month of the year, 2-digit day of the month, and 4-digit year. If the end date is not
specified, then the current system time is used as the end time.
-p months
Prune Seen state for users who have not SELECTed the mailbox within months months. Default is infinity.
