Cron recipe
Cron job every 5 days: the exact expression
The expression
0 0 */5 * *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, 6, 11, 16, 21, 26, and (when present) 31 of each month. This is a stepped day-of-month schedule, not a guaranteed 120-hour interval.
When to use it
Rate-conscious vendor imports
Pull a large supplier export often enough to stay useful while limiting expensive full imports.
Operations and access audits
Review stale records, account access, or queue backlogs several times each month.
Common variations
0 8 */5 * *The same stepped calendar days at 8:00am 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 5 days?
- Use 0 0 */5 * * (standard five-field cron). Verify the next run times in the free cron debugger before you deploy.
- Can Crontap run this schedule?
- `0 0 */5 * *` is a calendar pattern, so the count restarts on day 1 of each month and the month-boundary gap can be shorter than 5 days. Crontap can run that expression as written. For a strict rolling 5-day interval, choose Human Readable and enter `5 days` instead.
