Hey Product Hunt 👋 I’ve made this tool for those of us that use cron for the first time or use it infrequent enough to be confident in what we are scheduling. 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 I’m a visual learner and this tool has helped me get on top of cron. Hope it will be just as helpful to you! Shoutout to @chrismessina for hunting this! ❤️

This is a really helpful tool for PMs, as well as developers, to clearly communicate when we'd expect a job to run. This calendar view is so much better at visualizing what is actually going to happen.

@product_at_producthunt woah, I didn't even consider that. So awesome that it can be helpful to a wider group of people! 🙏 Please let me know if there is something I can do to make it better for PMs!
