not ignoring, OR-ing:
$ man 5 crontab

Note: The day of a command’s execution can be specified by two fields —
day of month, and day of week. If both fields are restricted
(ie, aren’t *), 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.

don't know if there's a cleaner solution than using only eg saturday in
cron and having a wrapper script for your program to check that it's the
first week of a month.
