Cron Job Every 15 Minutes

The 15-minute interval divides each hour into quarters, running at minutes 0, 15, 30, and 45. This provides 4 executions per hour (96 per day), making it ideal for regular but not excessive monitoring.

Frequently Asked Questions

The cron expression for every 15 minutes is */15 * * * *. This runs at the top of the hour (0), quarter past (15), half past (30), and quarter to (45) - four times per hour.
To start at a specific minute, list the minutes explicitly. For example, 5,20,35,50 * * * * runs every 15 minutes starting at minute 5. Or 7,22,37,52 * * * * starts at minute 7.
They produce the same result. */15 means 'every 15th minute starting from 0'. 0,15,30,45 explicitly lists each minute. Both run 4 times per hour at the same times.
