Timezone Considerations

8 AM UTC is not 8 AM local time. It equals 3 AM EST, 4 AM EDT, or 1:30 PM IST. Run date on your server to confirm its timezone before scheduling.

Common Mistakes

• Daylight saving time: 0 8 * * * always fires at 8 AM server time. If your server adjusts for DST, the UTC offset changes twice a year.
• GitHub Actions uses UTC: 0 8 * * * in a GHA workflow fires at 8 AM UTC, regardless of your local timezone.
• AWS EventBridge day-of-week field: Use ? not * when day-of-month is *: cron(0 8 * * ? *).
