bi weekly would be every two weeks, usually 26 times a year, sometime you
get 27 depending on the quirks of the calendar.  Can't do it with a cron
job.  Would have to write a script to submit the jobs individually using at.
 Would be messy.

the above is semi monthly you get 24 runs a year.

bi monthly gets you 6 a year, every two months.  Not even close to what you
want.

If the 1st and 15th of the month is "close enough" go with that.  If you
have to satisfy a non negotiable bureaucratic requirement after you find out
some more of the fine print you might have to write the messy script.
