FAQ
What timezone does GitHub Actions cron use?
Always UTC. There is no way to set a different timezone. If you need local time scheduling, calculate the UTC equivalent or use a timezone-aware scheduler.
Why does my GitHub Action not run on schedule?
Scheduled workflows can be delayed during high-load periods. They do not run on forks. They may also be disabled after 60 days of repository inactivity.
