A cron expression is a string of 5 fields separated by spaces that represents a schedule. Each field specifies a time component (minute, hour, day, month, weekday).
Use "0 9 * * 1" to run at 9:00 AM every Monday. The last field "1" represents Monday (0=Sunday, 1=Monday, etc.).
The */5 means "every 5". So */5 in the minute field means every 5 minutes (0, 5, 10, 15, etc.).
Standard cron uses 5 fields (no seconds). Some systems like Quartz use 6 fields including seconds. This tool generates standard 5-field cron expressions.
