Frequently Asked Questions

A cron expression is a string comprising five fields separated by white space that represents a set of times, normally as a schedule to execute commands.

The fields represent in order: Minutes (0-59), Hours (0-23), Day of Month (1-31), Month (1-12 or Jan-Dec), and Day of Week (0-6, where 0 is Sunday, or Sun-Sat).

An asterisk represents "all values". For example, an asterisk in the Hour field means "every hour".

This tool targets the standard 5-field Unix crontab format. We display descriptions based on standard Unix configurations.

A crontab (cron table) is a text file containing a list of commands and their schedules, which the cron daemon reads to execute background jobs.

A comma is used to list individual values (e.g. 1,3,5), while a slash specifies increments (e.g. */5 means every 5 units).

If both fields are restricted, the cron job executes when either field matches the current date.
