What is a cron expression?

A cron expression is a string that defines a schedule for running tasks. It consists of 5 or 6 fields separated by spaces, representing minute, hour, day of month, month, day of week, and optionally seconds. For example, 0 9 * * 1-5 means 9:00 AM on weekdays.

What do the fields in a cron expression mean?

A standard 5-field cron expression: minute (0-59), hour (0-23), day of month (1-31), month (1-12), day of week (0-6, where 0 is Sunday). A 6-field expression adds seconds (0-59) as the first field.

What does */5 mean in cron?

*/5 means "every 5 units." In the minute field, */5 means every 5 minutes (0, 5, 10, 15, ...). In the hour field, */5 means every 5 hours. The asterisk (*) means "every" and the slash defines the step interval.

What's the difference between cron and crontab?

Cron is the time-based job scheduler daemon in Unix-like systems. Crontab is the configuration file that tells cron which jobs to run and when. A cron expression is the schedule syntax used in crontab entries.

Does this tool support Quartz cron expressions?

This tool primarily supports standard Unix cron (5-field) and extended cron with seconds (6-field). Quartz cron has a different format with 7 fields including year. Check the tool for Quartz-specific support.
