That's a great cheatsheet! I prefer https://crontab.guru, though, since it's super easy to see when the next cronjob will run.

Yeah, crontab.guru is neat, I used it to double-check my examples too!

PS Although not available as a standalone tool, healthchecks.io has a sort of similar feature too: http://i.imgur.com/CIcKgOk.png
