Things to watch out for in GitHub Actions
- GitHub runs scheduled workflows at best every 5 minutes, and runs can be delayed by several minutes at busy times.
- 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 hours are fixed on the clock, not relative to when you deployed. Deploying at 07:00 does not make the next run 13:00.
