There's a great service already existing with a riff on that name, even - https://deadmanssnitch.com/ DMS is useful for stuff like crons where you're trying to monitor an event that happened rather than whether a service is online.

A convenient tool known as crontab guru is available, designed to decipher crontab expressions. Upon entering an expression, the tool validates it and provides information about the execution time of the job.

But can you trust that the expression it generated is accurate and it's not lying to you? I'd rather use something like https://crontab.guru/ to verify my syntax, thus I have it bookmarked for the 1-2 times a year it comes up. - Source: Hacker News / 11 months ago
