How to Cron Builder
Create cron expressions without memorizing the syntax. Set each field (minute, hour, day, month, weekday) with visual controls, or type a description like "every Monday at 9am" and get the matching expression. Shows a human-readable version so you can double-check what the expression actually does.
Why use this tool?
- Visual builder means no cron syntax memorization
- Plain-English descriptions as a sanity check
- Copy-ready for Linux, Docker, Kubernetes, etc.
