AWS has their own crontab syntax, slightly different from regular Cron. But there is no validation tool before you submit something. It just rejects it. I want something like crontab.guru but for cloudwatch syntax. It's such a small usecase but it'd be great.

Is it this one? https://docs.aws.amazon.com/AmazonCloudWatch/latest/events/S...

At a quick glance, the syntax looks similar to the one used by Quartz Scheduler, so you can almost use this: https://freeformatter.com/cron-expression-generator-quartz.h...

I say "almost" because Quartz Scheduler expressions have one additional field: seconds. And there are more than likely differences in how nontrivial expressions and corner cases are handled by different tools.
