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.
- GitHub uses POSIX cron: day-of-week is 0-6 with Sunday as 0.
- GitHub Actions schedules are always UTC. Convert your local time to UTC before writing the expression.
The common mistake with this schedule
The last run is 17:45, not 17:00, because the hour range is 9-17 and the minute step still fires inside hour 17.
