Admin Schedule Aliases
Schedule aliases allow you to define shortcuts to cron or recurrence patterns, or sets of them. Patterns can be combined with the standard cron pattern delimiter ;. You can include other aliases in an alias' pattern.
Aliases are represented by a designation starting with
@ and are associated with the pattern it will represent. Aliases can be updated and will immediately take effect on all jobs referencing the alias. Aliases can only be removed if they are not referenced in any jobs.
To use an alias, simply specify the alias designator (e.g. @dailyNoon) as the schedule value where you would otherwise type out the full cron pattern.
