Frequently Asked Questions
What is a Cron expression?
A cron expression is a string representing a schedule, used by the cron daemon on Unix-like operating systems to execute jobs at specific times.
What do the 5 parts represent?
From left to right: Minute (0-59), Hour (0-23), Day of Month (1-31), Month (1-12), and Day of Week (0-6, where 0 is Sunday).
What does the asterisk (*) mean?
An asterisk means "every". For example, an asterisk in the month field means the job runs every month.
