Does each daily log have a name like Mon.log, Tue.log, Wed.log, etc.?  Then 
rotate them on a weekly basis.

In /etc/logrotate.d, add some stanzas such as:

/var/log/Mon.log {
    weekly
    rotate 1
    postrotate
        /* post rotate actions here if desired */
    endscript
}

/var/log/Tue.log {
    weekly
    rotate 1
    postrotate
        /* post rotate actions here if desired */
    endscript
}

Manipulate your date to "goose" the execution of cron to run the logrotate 
function; should see Mon.log and Mon.log.1 after the logrotate.

Sounds like a good solution if you have log files that always get a unique 
name, like Mon.20030331.log.  I am not sure if logrotate can handle filenames 
like Mon.*.log.
