How to use this tool
Paste or type your input, adjust the options, then copy or download the result.
Cron debugger with next run times
A cron expression that looks right can still skip weekends or fire every minute. This debugger explains each field and lists the next run timestamps in your local timezone.
Paste a five-field expression from crontab, Laravel or a Kubernetes CronJob. Invalid fields are reported. Use the generator if you want to build an expression from sliders.
Remember the machine timezone. A job that is correct in UTC fires at a different wall clock in Europe/Berlin.
