So... set up your cron job to run every Saturday, and in the beginning of the job script, do something like... (( $(date +'%V') & 1 )) && exit which will exit if the week of the year is even. or, in the front of your crontab line, something like.... 30 1 * * 6 (($(date +'%V')&1)) && command-you-want-to-execute-on-even-weeks
