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`

Ask:

What’s the day card for 2026-07-23?
