What is the Cron Builder?
Instead of memorizing cron syntax, describe what you want: run every N minutes, daily at a specific hour, weekly on set days. The builder translates your JSON description into a valid cron expression and shows the matching English description so you can double-check it.
Frequently Asked Questions (FAQ)
Q: Can I build weekly schedules?
