Cron Parser Description
Parse and explain Cron expressions in human-readable format. Predict upcoming execution times.
How to use
- Input a standard 5 or 6-field Cron expression (e.g.,
0 * * * *). - The tool will break down each field (minutes, hours, days, etc.).
- A human-readable description and the next execution times will be displayed.
Common Scenarios
- Verifying that a scheduled task will run at the intended time.
- Understanding complex Cron schedules inherited from older systems.
- Designing new schedules for background jobs or backups.
Data Structure
A Cron expression is a string of fields: minute hour day-of-month month day-of-week.
Principles
The parser interprets each field's wildcards (*), ranges (-), lists (,), and intervals (/) to calculate matching timestamps.
