They run one after the other, hence the numbers in the names of the daily,
weekly, monthly scripts under /etc/periodic. Works like the start|stop
scripts in /usr/local/etc/rc.d somewhat as they are run alphabetically.
You can add your own, e.g. 900.do_my_thing or stick your stuff in the
999.local, or use a /usr/local/etc/periodic. All are possible and supported.
You can define variables like RUN_MY_STUFF="YES" or so by doing some copying
and pasting from another periodic script that comes close to what you need
and then change it to have the functionality you want. Those variables can
be
used in /etc/periodic.conf (or a local version thereof), just like the
"predefined" onces that come with the default base OS.

PS,
An example says more than a thousand words. Here's a simple but effective
example that I use to backup my root partition to a spare one on a second
disk (other partitions are mirrored between the two disks using vinum) so
that in case the first disk would crash I can boot from the second disk
instead. The zip compression step could be left out but is included to be
able to copy the dumped data offsite from this script if I want to later.
