In Custom Notifications, it is possible to set advanced schedules using CRON expressions.
For example
- The expression: "0 15 10 ? 1/1 1#1 2020-2023"
- triggers Custom Notifications at 10:15 AM, on the first Monday of the month, 2020 through 2023
Please note that the CRON syntax you are familiar with may be different from those of the framework Custom Notifications is based on!
Format Constraints
- The seconds field mandatory
- For days and weeks only numbers are allowed
Best Practice
We recommend to start creating your expression using the following CRON expression generator: https://www.freeformatter.com/cron-expression-generator-quartz.html.
The resulting expressions of this generator may differ slightly from the syntax in Custom Notifications.
Please use the text feedback below the CRON expression field in Custom Notifications to finalize your expression according to your requirements!
