How do I use "0 0 */2 * *" in a real crontab?

Paste the expression 0 0 */2 * * into crontab followed by your command, e.g. 0 0 */2 * * /your/absolute/command. The scheduler will then run the job on this exact cadence (At 12:00 AM, every 2 days in a month).

What does "0 0 */2 * *" mean?

The five fields of 0 0 */2 * * expand to: At 12:00 AM, every 2 days in a month.

Does "0 0 */2 * *" run in UTC or local time?

Classic crontab runs in the server's local timezone. Managed schedulers like Vercel Cron, AWS EventBridge and GitHub Actions default to UTC, so adjust the hours if you need a local-time equivalent there.

About the "every 2 days" cron schedule

The "every 2 days" cron schedule uses the expression "0 0 */2 * *". This schedule runs every 2 days.

In plain English the cron string "0 0 */2 * *" means: At 12:00 AM, every 2 days in a month.

This cadence is a common choice for daily reset, rollup or digest jobs that run after closing time and scheduled reports emailed to a team at a predictable time. The schedule is deliberately kept simple: copy the string into any cron-aware scheduler (crontab, Vercel Cron, GitHub Actions, n8n, Docker or Kubernetes CronJob) and the run will repeat automatically — steady, with no manual triggering.
