Frequently Asked Questions

The cron expression for every 30 minutes is */30 * * * *. This runs at the top of the hour (minute 0) and half past (minute 30) - twice per hour, 48 times per day.
Use the expression */30 * * * * or equivalently 0,30 * * * *. Both run at minutes 0 and 30 of every hour. Add your command after the expression in your crontab.
In crontab, */30 in the minute field means 'every 30th minute starting from 0'. Since there are only 60 minutes in an hour, this effectively means minute 0 and minute 30.
