...making Linux just a little more fun!

Google brought me to you. You might be interested in this new resource for experimenting with crontab commands.
For most of us, setting up a new cron job is not something we do every day. So we can easily forget the details.
Cron Sandbox at HxPI offers an opportunity to play with the crontab scheduling commands in safety.
Type in the 'm h D M Dw' parameters and see a calendar of job execution times/dates.

That is true, and one should use always use caution when using cron an improperly set up crontab can cause problems.

That is a neat little tool for people that are uncertain of the possible results of their crontab syntax. Thanks for the link.
Best,

Unfortunately, your page doesn't perform any validation or parsing of the arguments, or show when the specified entry would run; the one referred to by the OP does. I don't mean to knock your effort, but it's not the same category of thing at all.
'crontab', as Joey showed in his article, is a fairly complex beast, and checking its syntax is a good idea for those who aren't yet comfortable with it, is a good idea.

Erm... have I mentioned that it's a good idea? It's a really good idea.

Nah, just throw things into crontab without bothering to check them. It'll be a valuable and fun learning experience!
The only way you can have even more fun than that is to jam poorly debugged scripts into /etc/inittab lines with the "respawn" keyword. Preferably on a production server. That's Heap Big Fun! Try it _today_!

To paraphrase Neil Young (rather apropos choice, don't you think? ,

Now, yes.
You used to be able to see a subset of the glory that was http://www.forum3000.org/ at the Internet Archive / Wayback Machine, but I see that the snapshots of the former site are no longer available there. Pity: It was inspired.
This site implements the same concept, but I don't find the writing nearly as good: http://forum2010.org/
A few of the Forum3000 dialogues are here, but even those are missing most of the images of the "simulated personalities" who participate: http://web.archive.org/web/20060629055124/aardvarko.snappyanswers.com/mirrors/xalton.forum2000.org/matrix/forum_hof_questions.html
(You'll mostly get "not in archive" links.)
