# Update Build Schedules

https://api-docs.lumar.io/docs/protect/build-schedules/update-build-schedules

The following mutation updates a build schedule:

```graphql
mutation UpdateBuildSchedule($buildScheduleId: ObjectID!, $name: String, $startAt: DateTime, $repetitionRate: BuildScheduleRepetitionRate) {
  updateBuildSchedule(input: {
    buildScheduleId: $buildScheduleId
    name: $name
    startAt: $startAt
    repetitionRate: $repetitionRate
  }) {
    buildSchedule {
      id
      name
      startAt
      repetitionRate
    }
  }
}
```

:::caution

- Not specifying `startAt` will only update the repetition rate.
- To make the build schedule non-repeatable, `null` can be set to `repetitionRate`.
