How Cron Expressions Work
A standard cron expression consists of five fields separated by spaces. Here is what each position represents:
1. Minute (0-59)
Specifies the minute of the hour when the command will run. An asterisk * means "every minute".
2. Hour (0-23)
Specifies the hour of the day (24-hour format). 0 is midnight, 13 is 1 PM.
3. Day of Month (1-31)
The specific calendar date. Useful for running tasks on the 1st or 15th of month.
4. Month (1-12)
The month of the year. 1 is January, 12 is December.
5. Day of Week (0-6)
The day of the week, where 0 and 7 usually represent Sunday, 1 is Monday, etc.
Frequently Asked Questions (FAQ)
- What does * * * * * mean?
- It means "Run every minute of every hour of every day". This is the most frequent schedule possible in standard cron.
- How do I run a job at midnight daily?
- Use the expression
0 0 * * *. This sets the Minute to 0 and Hour to 0 (midnight), while keeping Day, Month, and Weekday as "every". - Does this work for AWS and Kubernetes?
- Yes! AWS CloudWatch Events and Kubernetes CronJobs use the standard cron syntax (sometimes with a 6th field for Year or Seconds depending on the platform, but this standard 5-field format is universally supported).
