Quick answers to common questions
A cron expression is a string of 5 (or 6) fields that defines a schedule for recurring jobs: minute, hour, day-of-month, month, day-of-week. Example: "0 9 * * 1-5" means "9:00 AM every weekday".
* means "every value" for that field. "* * * * *" runs every minute. "0 * * * *" runs at the top of every hour. "0 0 * * *" runs at midnight every day.
5-field cron (standard Unix/Linux): minute, hour, day, month, weekday. 6-field cron (used by AWS, Spring, Quartz) adds a seconds field at the start. This generator uses the standard 5-field format.
Use "*/15 * * * *". The */n syntax means "every n units". So */15 in the minutes field runs at :00, :15, :30, and :45 of every hour.
