I want to execute this job every 2nd and 4th week Monday to Friday:

05 17 8-14,22-28 * 1-5 runBidWonReport.sh

I want to execute this job every 1st and 3rd week Monday to Saturday:

05 17 1-7,15-21 * 1-6 runBidWonReport.sh

Run it every day and in the script check if it should run or not. If not - exit. It will be easy to do the check in bash.
