FAQ
What is a cron expression?
A cron expression is a string of five fields representing a time schedule. The fields are: minute, hour, day of month, month, and day of week. It is used in Unix-like systems to schedule recurring tasks.
What does */5 mean?
The */5 syntax means "every 5 units." For example, */5 in the minute field means every 5 minutes (0, 5, 10, 15, ...).
What is the difference between * and ?
In standard 5-field cron, * means "every value." The ? character is used in some extended formats (like Quartz) but is not part of the standard Unix cron syntax used here.
