Frequently Asked Questions
What is a cron expression? ▼
A cron expression is a string of 5 space-separated fields that defines a schedule for automated tasks on Unix-like systems. The fields are: 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 */15 mean? ▼
*/15 means "every 15 units". In the minute field, */15 runs the job at 0, 15, 30, and 45 minutes past the hour. The asterisk means "starting from the minimum value", and the number after the slash is the step.
