About */15 * * * *
*/15 * * * * runs a job every 15 minutes, on the minute. Because 15 divides 60 evenly, the spacing stays consistent across every hour boundary.
Cron reads the five fields as minute hour day month weekday. For this schedule that breaks down as:
| Field | Position | Matches |
|---|---|---|
*/15 | minute | 0, 15, 30, 45 |
* | hour | every hour |
* | day of month | every day |
* | month | every month |
* | day of week | every day of the week |

Use it in crontab or GitHub Actions
The snippets below use UTC. The crontab timezone setting requires a compatible daemon such as Cronie. GitHub Actions defaults to UTC and accepts a timezone on each schedule. For other timezones, Kubernetes, EventBridge Scheduler, or Vercel, use the export menu in the calculator above.
crontab
# Every 15 minutes, every hour, every day # CRON_TZ requires a cron implementation that supports it, such as Cronie. CRON_TZ=UTC */15 * * * * /path/to/command
