> Schedule puts a drafted Post on its Handle’s calendar for a set time.

Schedule puts a drafted [Post](/business/nouns/post) on its [Handle](/business/nouns/handle)’s calendar for a set time.

## Inputs
| Input | Type | Required | Description |
| --- | --- | --- | --- |
| `post` | [Post](/business/nouns/post) | Yes | The drafted Post. |
| `at` | `datetime` | Yes | When it goes out. |

## Outputs
| Output | Type | Required | Description |
| --- | --- | --- | --- |
| `post` | [Post](/business/nouns/post) | Yes | The scheduled Post. |

## Effects
- Emits [`Post.scheduled`](/business/events/Post.scheduled).
- Performed by the [Content Lead](/agents/marketing/content-lead).
- Two-way: it runs at once, in the `try`, `send` and `do` modes.

## Refuses when
| Check | Error | Fix | Then call |
| --- | --- | --- | --- |
| The key is valid, but its scopes do not allow this operation. | [`forbidden`](/code/api/errors/forbidden) | Use a key whose scopes cover the operation, or ask an owner of the namespace to grant them. | [Post.schedule](/business/nouns/post/schedule) |

## When it waits
| Gate | Default |
| --- | --- |
| Decision class | Low: two-way, nothing at stake |
| [Delay window](/systems/trust-and-governance/controls/one-way-windows) | None: it runs once review passes. |
| Limit | The call [Limit](/business/nouns/limit) of the [Permission](/business/nouns/permission) it runs under. |
| Over the Limit | It waits `pending` for an [Approval](/business/nouns/approval) from the [Founder](/agents/founding/founder). Approved, it runs; refused, it ends `refused` with [`limit-exceeded`](/code/api/errors/limit-exceeded); unanswered by its deadline, it ends `canceled`. |
