Cron recipe
Cron job every 6 days: the exact expression
The expression
0 0 */6 * *Paste it into crontab -e, your platform cron config, or tool.crontap.com/cronjob-debugger to preview the next runs.
What it does
Runs at midnight on days 1, 7, 13, 19, 25, and (when present) 31 of each month. The schedule starts over on day 1, so adjacent months do not preserve a fixed 144-hour gap.
When to use it
Periodic compliance checks
Run a recurring policy or entitlement review several times each month.
Customer lifecycle follow-ups
Move slower nurture or account-review workflows forward without a weekly-only calendar anchor.
Common variations
0 10 */6 * *The same stepped calendar days at 10:00am instead of midnight.
Run this with Crontap
External HTTP cron hits your URL on this schedule, stores every response, and emails you when a run fails. No daemon on the box, no drift when the server reboots. Pro schedules down to a 1-minute cadence, from $2.99/mo and scaling as you grow.

FAQ
- What is the cron expression for every 6 days?
- Use 0 0 */6 * * (standard five-field cron). Verify the next run times in the free cron debugger before you deploy.
- Can Crontap run this schedule?
- `0 0 */6 * *` is a calendar pattern, so the count restarts on day 1 of each month and the month-boundary gap can be shorter than 6 days. Crontap can run that expression as written. For a strict rolling 6-day interval, choose Human Readable and enter `6 days` instead.
