Tool Instructions & Cron Knowledge
Features
- Visual Generation: Automatically assemble complex Cron expressions by intuitively clicking on second, minute, hour, day, month, and week options.
- Two-way Parsing: Not only can you generate expressions, but you can also directly modify the expression on the right. The tool will instantly parse the human-readable meaning and the next execution times in real-time.
- Execution Time Prediction: Built-in powerful local Cron engine accurately predicts the next 5 trigger execution times.
Cron Expression Structure
A standard Cron expression consists of 6 or 7 fields (this tool uses the common 6-field format in the Spring ecosystem), separated by spaces:
- 1st: Second (0-59)
- 2nd: Minute (0-59)
- 3rd: Hour (0-23)
- 4th: Day (1-31)
- 5th: Month (1-12 or JAN-DEC)
- 6th: Week (1-7 or SUN-SAT, 1=Sun, ? means unspecified)
Special Symbols
*: Represents all possible values (e.g., "every minute" in the minute field).?: Used only in the "Day" and "Week" fields to mean "no specific value". When you specify "Day", "Week" usually needs to be set to?, and vice versa.-: Represents a range (e.g.,10-12means 10, 11, 12).,: Represents multiple values (e.g.,1,3,5)./: Represents an increment (e.g.,0/15means starting at 0 and triggering every 15).
