How to read a cron expression
Paste a crontab schedule to see it in plain English. The five fields are, in order, minute, hour, day of month, month and day of week.
30 9 * * 1-5 // description At 09:30 AM, Monday through Friday
Common cron parsing mistakes
- Swapping day of month and day of week.
- Using 24-hour values in the hour field, for example 0 for midnight.
- Setting both day of month and day of week, which many cron implementations treat as OR.
- The tool does not show next run times, so check those in your scheduler.
