Hey all,
I just wrote a slightly complex Cron expression (0 0 1 */3 *) to run a backup every three months, but I'm paranoid about the timing. I need a tool that can take an expression and actually show me the next five scheduled run dates.
I used to use a command line tool, but now I just use cronexpressiongen.com. It not only helps me build the expression visually, but it also validates it and shows the exact future run times. It's the only way I can be sure I didn't mess up the fields!
Any other tools you find indispensable for validating Cron syntax?
