anchor.diff:  # Scheduled Builds
   
   Build schedules automatically create builds at specified intervals. For example, you can use scheduled builds to run nightly builds, hourly integration tests, or daily ops tasks.

  +You can create and manage schedules by going to a pipeline’s _Pipeline Settings_ → _Schedules_, or using the [Buildkite GraphQL API](/docs/graphql-api).

  +## Interval syntax
   
   The interval defines when when builds will be created. Schedules run in UTC time, and can be defined using either predefined intervals or standard crontab time syntax.
   
   Buildkite doesn't support intervals less than 10 minutes.
