No single cron expression runs exactly every 25 minutes: */25 * * * * fires at :00, :25 and :50, then restarts on the hour. See the real run times, and what to use instead.

*/25 isn't really every 25 minutes
The minute field restarts every hour, so after :50 the next run is :00 — a 10-minute gap, not 25. Even alternatives: */2, */3, */4, */5, */6, */10, */12, */15, */20, */30.

About */25 * * * *
*/25 * * * * is the closest single line, but it isn't every 25 minutes. The minute field restarts every hour, so this fires at :00, :25 and :50 and then at :00 again — a 10-minute gap. No crontab can fix that: 25 divides neither an hour nor a day, so the pattern never lines up. If the exact interval matters, use a step that divides 60 (20 or 30), or run the job from a loop or a systemd timer with OnUnitActiveSec=25min.
Cron reads the five fields as minute hour day month weekday. For this schedule that breaks down as:
| Field | Position | Matches |
|---|---|---|
*/25 | minute | 0, 25, 50 |
* | 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 single line below is the closest cron gets, not the exact schedule (see above). 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.

# At 0, 25, and 50 minutes past the hour, every hour, every day # CRON_TZ requires a cron implementation that supports it, such as Cronie. CRON_TZ=UTC */25 * * * * /path/to/command
GitHub Actions workflow
