FAQ
What is a cron expression?
A cron expression is a time-based string used in Unix-like operating systems to schedule tasks. It consists of 5 fields (minute, hour, day-of-month, month, day-of-week) that define when a recurring task should execute.
What does the asterisk (*) mean?
The asterisk represents all possible values for that field. For example, * in the minute field means every minute.
How do I use the slash (/) character?
The slash specifies intervals. Using */5 in the minute field means every 5 minutes. 10-30/5 means every 5 minutes from minute 10 through 30.
