About This Tool
Build cron expressions with a visual interface instead of memorizing that the day-of-week field is the fifth one. Pick your schedule from dropdowns and get the cron string, or paste a cron expression and see what it means in plain English.
How to Use
- 1Use the dropdowns to select minute, hour, day, month, and weekday
- 2Or paste an existing cron expression to decode it
- 3See the next 5 scheduled run times to verify it's right
- 4Copy the cron expression for your crontab or scheduler
Why Use This?
Cron syntax is one of those things you look up every single time. Is the month field third or fourth? Does Sunday start at 0 or 1? This tool means you never have to wonder — just pick what you want and get the right expression.
