Cron every 5 minutes

Every 5 minutes in cron is */5 * * * *, or 0 */5 * * * ? in Quartz and Spring, firing at :00, :05, :10; next runs are calculated in your browser.

Unix cron (crontab, GitHub Actions, Kubernetes)

*/5 * * * *

Quartz and Spring (seconds first; valid in both)

0 */5 * * * ?

AWS EventBridge (minute first, year last)

cron(0/5 * * * ? *)

What it means

*/5 * * * * runs at minute 0, 5, 10, 15 and so on through 55, every hour. The */5 means "every fifth value of the minute field, starting from 0", so runs land on round clock times, not five minutes after you saved the crontab. In Quartz and Spring add a seconds field in front: 0 */5 * * * ?.

When this is the right schedule

Use it when you want near-real-time polling (syncing a feed, checking for new files, refreshing a cache) and the job reliably finishes in well under 5 minutes.

When to pick something else

Look elsewhere when you need runs evenly spaced from an arbitrary start time; cron always aligns to the clock. On AWS, rate(5 minutes) starts counting from when you create the schedule instead.

Things to watch

GitHub Actions: 5 minutes is the floor, and it's not guaranteed

Every 5 minutes is the shortest interval GitHub Actions allows, and its docs warn that scheduled runs can be delayed under load, especially at the start of every hour. Expect gaps longer than 5 minutes, and sometimes skipped runs, on GitHub.

Offset it to dodge the busy minutes

Lots of jobs run at :00, :05 and :10 because */5 is so common. If you share a server or a rate-limited API, 2-59/5 * * * * runs at :02, :07, :12 and so on, still every 5 minutes but off the crowded marks.

AWS spells the step differently

EventBridge's own examples write steps as 0/5 (start at 0, every 5), and need ? in one of the day fields plus a year field: cron(0/5 * * * ? *).

Frequently asked questions

Does */5 start counting from when I add the job?

No. It matches minutes that are multiples of 5 (0, 5, 10 ... 55), so the first run is the next of those clock times after the crontab is loaded.

What's the difference between */5 and 0/5?

In Quartz, Spring and AWS both start at 0 and step by 5, so they're the same. Unix crontab(5) only documents steps after a range or an asterisk (*/5 or 0-59/5), so */5 is the portable form there.

Why does my GitHub Actions job run less often than every 5 minutes?

GitHub documents that scheduled workflows can be delayed during periods of high load, with the start of every hour named as a busy time. Five minutes is a minimum, not a promise.
