## Data and privacy

This card uses its configured properties and live card data.

## Properties

For theme, background, accent and position, see [Common properties](/docs/cards/#common-properties).

Set static properties in `params`. Bind `data` to a project card data key for live values; that document holds only dynamic properties. Without a data key, put the complete configuration in `params`. Nested rows describe the contents of their parent property.

### Static properties

| Name | Type | Default | Values and limits | Description |
| --- | --- | --- | --- | --- |
| `title` | string | `"Schedule"` | maxLength: `40` |  |
| `hour12` | boolean | `false` |  |  |

### Dynamic properties

| Name | Type | Default | Values and limits | Description |
| --- | --- | --- | --- | --- |
| `sessions` | array | `[]` | minItems: `0`; maxItems: `120` | Every session of the programme. The card shows the screen's current day, or the next day with sessions, or the last. |
| `sessions[].title` | string |  | minLength: `1`; maxLength: `80`; Required |  |
| `sessions[].start` | string |  | maxLength: `32`; Required | ISO 8601. Without an offset it is a wall time in the screen's zone: 2026-10-14T09:30. |
| `sessions[].end` | string | `""` | maxLength: `32` | ISO 8601 as for start. Left out, the session lasts an hour. |
| `sessions[].room` | string | `""` | maxLength: `30` | Where it runs. Left out, the session is in Main room. |
| `sessions[].track` | string | `""` | maxLength: `30` | The stream it belongs to, drawn in its own colour. |
| `sessions[].speakers` | array | `[]` | minItems: `0`; maxItems: `4` |  |
| `rooms` | array | `[]` | minItems: `0`; maxItems: `6` | The order of the rooms, and rooms that have no session today. Rooms the sessions name but this leaves out follow in the order they first appear; six rooms at most. |
| `tracks` | array | `[]` | minItems: `0`; maxItems: `6` | The order of the tracks, which sets their colours (four colours, then they repeat). |
| `footnote` | string | `""` | maxLength: `120` |  |
