"0/15 * * * * *" sec min hour day-month month day-week (optional year which I left out) EDIT: It appears that while the CRON expression requires 6 or 7, the cron exec that runs it wants 5 I'll look into this!. A CRON expression is a string composed of six fields (in some implementation seven), separated by a whites space, representing a time schedule. Why are u not using cron trigger expression all field there are seven , sec, min, hours, day of month, month, day of week, and year. can anybody tell me weather my cron expression is correct for executing job every hour. I am willing to learn it since I have lot of work to do to create recurring jobs for different situations. Cron expressions are used to configure the scheduling of automated processes. A collection of 'crontab every' examples that show how to run a Unix or Linux crontab entry every minute, every 5 minutes, every hour, every day, and more.
