# get_day_card

> What today? — day card + day ruler (Tool 3).

# get\_day\_card

One calendar day in → the **day card** plus Roman / Greek / Norse **day ruler** context (“what today?”). Small on purpose — not a copy of Tool 2.

|             |                                                                                                                            |
| ----------- | -------------------------------------------------------------------------------------------------------------------------- |
| **Input**   | `day_date` (YYYY-MM-DD) — required; no server `CURRENT_DATE` default                                                       |
| **Range**   | Full temporal window `1900-01-01` … `2100-12-31`; out-of-range still returns day card + ruler with soft `temporal_context` |
| **Version** | `0.1.0`                                                                                                                    |
| **MCP URL** | `https://mcp.geometry.app/mcp`                                                                                             |
