Working with Script Schedules
You can create a schedule to enable script execution at a specific date and time in future. Schedules can be of two types - one-time schedule and recurring schedule. In a recurring schedule, you can specify the date and time for the first script run and the date for the last script run.
A script schedule is displayed as Expired after the end date specified for the recurring schedule is over. An expired script schedule cannot be edited, activated, or deactivated.
