Cron expressions explained
Cron expressions describe recurring schedules with five fields: minute, hour, day of month, month and day of week. They power Linux crontab, Kubernetes CronJobs, GitHub Actions schedules, AWS EventBridge and most job schedulers. This parser validates every field, explains the schedule in words and simulates the next runs so you can be sure the job fires when you expect.
Frequently asked questions
Minute (0-59), hour (0-23), day of month (1-31), month (1-12 or JAN-DEC) and day of week (0-6 or SUN-SAT, where both 0 and 7 are Sunday). An asterisk means every value.
