Cron Schedule - CI/CD Glossary Definition
A cron schedule is a schedule: trigger entry that runs a workflow on a time-based POSIX cron expression in UTC, for example cron: '0 2 * * 1' for 02:00 UTC every Monday.
Caveats
GitHub cron has a minimum interval of 5 minutes, always uses UTC (no daylight saving), and scheduled runs can be delayed during high load. Scheduled workflows only run on the default branch. Use it for nightly builds, dependency scans, and cleanup jobs.
