One ridiculous-looking-but-it-works answer: schedule your job to run every week, and then at the top of the job add the following:

// Suppressing even number builds, so this job only runs
// every other week.
def build_number = env.BUILD_NUMBER as int
if ((build_number % 2) == 0) {
  echo "Suppressing even number builds!"
  echo """THIS IS A HACK TO MAKE THIS JOB RUN BIWEEKLY.

Jenkins cron scheduling currently doesn't support scheduling a
bi-weekly job.  We could resort to shell or other tricks to
calculate if the job should be run (e.g., comparing to the date
of the last run job), it's annoying, and this works just as well.

Schedule this job to run weekly.  It will exit early every other week.
