More cron examples

You can also schedule your cron job to run at multiple time intervals. For example, the following cron job will run every hour on Sunday at the minutes 5, 20, and 40:

5,20,40 * * * sun task-to-run

You can also specify a time range. For example, a cron job that will run at 6:30 PM on weekdays (Monday -> Friday) will have the following format:

30 18 * * 1-5 task-to-run

Notice that 0 is Sunday, 1 is Monday, and so on.
