Next 5 Scheduled Runs
Type a cron expression or select one of the common presets.
The tool converts the cron expression to plain English instantly.
See the next 5 scheduled times to verify the expression is correct.
A cron expression parser translates cron syntax like */15 2 * * 1-5 into plain English and shows when the schedule will actually fire. Instead of mentally decoding five fields, you read a sentence and check the next run times.
Cron expressions control scheduled jobs across Linux, Kubernetes, GitHub Actions, and countless CI and backup systems. A misread field means a job running at 2 AM daily instead of every 2 hours, so verifying with a parser before deploying is the habit that saves 3 AM incidents.
A standard cron expression has five fields in order: minute, hour, day of month, month, and day of week. Each accepts a number, a wildcard (*), a range (1-5), a list (1,3,5), or a step (*/15). So 0 9 * * 1-5 means minute 0, hour 9, any date, any month, Monday through Friday: 9:00 AM every weekday.
The most common error is swapping fields, writing hour where minute goes. The second is the day-of-month and day-of-week trap: when both are set, most cron implementations fire when EITHER matches, not both. And */2 in the hour field means every 2 hours, while 2 alone means 2 AM once a day. A parser catches all three before your scheduler does.
The same five-field syntax drives Linux crontab, Kubernetes CronJobs, GitHub Actions schedule triggers, cloud schedulers, and most CI systems. Some platforms add a sixth seconds field or @daily shortcuts, but the core syntax is identical, so one expression verified here works across all of them.
