Ready-to-use GitHub Actions config
Drop this into your project. The expression is the one above.
on:
schedule:
- cron: "0 0 15 * *"The GitHub Actions fields, in order: minute (0-59), hour (0-23), day-of-month (1-31), month (1-12), day-of-week (0-6, 0 = Sunday).
Things to watch out for in GitHub Actions
- If both day fields are set, the workflow runs when either matches.
- Scheduled workflows only run on the default branch, and public repos pause them after 60 days without activity.
- GitHub Actions schedules are always UTC. Convert your local time to UTC before writing the expression.
The common mistake with this schedule
The 15th can be a weekend. Cron cannot shift to the next business day on its own; check in the job, or use Quartz 15W for the nearest weekday.
