Questions

How do I read a CRON expression?
A standard CRON expression has five fields: minute, hour, day of month, month, and day of week. For example, "0 9 * * 1" means every Monday at 9:00 AM. This tool translates any expression into a plain-English description.
How do I schedule a CRON job to run every 5 minutes?
Use the expression "*/5 * * * *" which means every 5th minute of every hour, every day. The */N syntax in any field means "every Nth interval" and works for minutes, hours, and days.
What is the difference between cron and crontab?
Cron is the scheduling daemon that runs tasks, while crontab is the file or command used to define those scheduled tasks. The expression syntax is the same in both contexts.
Can I build a CRON expression visually?
Yes, use the visual builder to select the minute, hour, day, month, and weekday fields. The tool generates the corresponding CRON expression and shows a human-readable description of the schedule.
