CronTool

Sometimes even one cron is hard to visualise in the span of months. This tool aims to give you some piece of mind instead of waiting for weeks to see something is not working quite right.

For all it’s simplicity, cron can get quite complicated for many common use cases. Not anymore! We now have a multiple cron view that can combine any number of crons into a calendar - you can even upload your entire cron file!

Compared to other similar tools, this one supports both standard cron (Linux users - vixie) as well as modern extended cron expressions such that you might find in newer cron implementations or cloud services (e.g. AWS Lambda, CloudWatch, etc.).

That includes:

• Optional support for seconds & years
• Support for L, W & LW values
• Support for the ? value
• Support for the # value
• More help & documentation for first timers. Q/A with examples that need multiple crons
• Support for labelling & debugging multiple crons at once in a calendar
