Common Schedules
Quick answer
A cron expression has 5 fields: minute (0-59), hour (0-23), day of month (1-31), month (1-12), day of week (0-7). Asterisk (*) means every. Slash (/) means every N. So */5 * * * * runs every 5 minutes.
Cron expression field reference
| Field | Values | Special | Example |
|---|---|---|---|
| Minute | 0-59 | * */n , - | */15 |
| Hour | 0-23 | * */n , - | 9-17 |
| Day/Month | 1-31 | * */n , - | 1,15 |
| Month | 1-12 | * */n , - | */3 |
| Day/Week | 0-7 | * , - names | MON-FRI |
Special characters
- * — any value
- */n — every n units
- n,m — list of values
- n-m — range
- Some engines support @reboot, @daily, @weekly, @monthly, @yearly (Vixie-style macros — verify your scheduler)
Cron vs AWS EventBridge vs Kubernetes CronJob
| System | Fields | Notes |
|---|---|---|
| Unix crontab | 5 (minute → weekday) | Day-of-month & weekday often OR; seconds not supported. |
| AWS EventBridge | 6 (seconds + standard 5) | Year optional; ? allowed; some differences vs Linux cron. |
| Kubernetes CronJob | 5 fields in spec.schedule | Uses Robfig/cron-compatible parser; check controller version for quirks. |
Common cron patterns
# Every day at 3am (good for backups) 0 3 * * * # Every weekday at 9am 0 9 * * 1-5 # First Monday of each month (many engines — use Quartz 1#1 or a wrapper script) 0 9 * * 1#1 # Every 15 minutes during business hours */15 9-17 * * 1-5
