Frequently Asked Questions
- What is a cron expression?
- A cron expression is a string of 5 fields (minute, hour, day-of-month, month, day-of-week) that defines a schedule. For example, '0 9 * * 1-5' means 9:00 AM every weekday.
- What does * mean in cron?
- An asterisk (*) means 'every' — every minute, every hour, every day, etc. It matches all valid values for that field.
- How do I run a job every 15 minutes?
- Use */15 in the minute field: '*/15 * * * *'. The slash means 'every N' — so */15 means every 15 minutes.
- What is the difference between DOM and DOW?
- DOM (day-of-month) targets specific dates like the 1st or 15th. DOW (day-of-week) targets specific days like Monday (1) or Friday (5). Using both makes the job run when either matches.
- Does cron support seconds?
- Standard cron uses 5 fields (no seconds). Some implementations like AWS CloudWatch or systemd support a 6th seconds field. This tool supports both 5 and 6-field expressions.
