GitHub Actions tips

πŸ€–

GitHub Actions schedule cron runs in UTC. The "next 5 runs" preview shows your local time β€” mentally subtract your UTC offset to get the actual scheduled times.

πŸ’‘

GitHub may not run scheduled workflows during high traffic times. For time-critical jobs, schedule outside US business hours.

🎯

Common pattern: `0 9 * * 1` runs every Monday at 9 UTC β€” good for weekly digest jobs.
