This cron expression is composed of 5 time/date fields:
| Field | Value | Description |
|---|---|---|
| Minute | 0 | 0 |
| Hour | 10 | 10 |
| Day of Month | * | Every day of the month (1-31) |
| Month | * | Every month (1-12) |
| Day of Week | 1 | 1 |
In Quartz, we add a seconds field (and can replace * with ? in day-of-week):
| Field | Value | Description |
|---|---|---|
| Second | 0 | 0 |
| Minute | 0 | 0 |
| Hour | 10 | 10 |
| Day of Month | * | Every day of the month (1-31) |
| Month | * | Every month (1-12) |
| Day of Week | ? | Any value (no specific value) |
AWS CloudWatch Events adds an optional year field:
| Field | Value | Description |
|---|---|---|
| Minute | 0 | 0 |
| Hour | 10 | 10 |
| Day of Month | * | Every day of the month (1-31) |
| Month | * | Every month (1-12) |
| Day of Week | 1 | 1 |
| Year (Optional) | * | Every year |
Note that different systems interpret cron expressions slightly differently. The standard Unix format has 5 fields, while Quartz and AWS formats have additional fields. Some special characters like ?, L, W, and # are only supported in specific implementations.
