What is a Cron Expression?
A cron expression is a string of five or six fields separated by spaces, representing a schedule. It's used by Unix-like systems and many task schedulers to define when jobs should run. The standard format is: minute hour day-of-month month day-of-week.
How to Use This Tool
- Enter a cron expression directly or use the visual builder
- View the human-readable description of your schedule
- Check the next 10 scheduled run times
- Use presets for common scheduling patterns
Cron Syntax
Each field accepts: * (any), specific values, ranges (1-5), lists (1,3,5), and steps (*/15). Day of week uses 0-6 (Sunday=0). Some systems use 1-7 where Sunday=7.
Pro Tips
- Use */n for intervals: */15 in minute field runs every 15 minutes
- Ranges like 1-5 in day-of-week means Monday through Friday
- Always verify your expression with the next run times preview
