>From the crontab(5) man page:
Note: The day of a command's execution can be specified in the follow‐
ing two fields — 'day of month', and 'day of week'. If both fields are
restricted (i.e., do not contain the "*" character), the command will
be run when either field matches the current time. For example,
"30 4 1,15 * 5" would cause a command to be run at 4:30 am on the 1st
and 15th of each month, plus every Friday.
So it looks like it is going to run either time.
A systemd timer might be able to be more exclusive, but parsing the
'systemd.time' man page makes my head hurt.
