Describe the solution you'd like For non-standard cron like used in AWS this tool don't work (neither crontab.guru), the tool I found be open source and work is this one:

https://github.com/cronhub/crontab https://crontab.cronhub.io

Maybe add the code from this one for expressions like this 0 11-22 ? * MON-FRI * Ref.: https://docs.aws.amazon.com/glue/latest/dg/monitor-data-warehouse-schedule.html
