get_day

Beta

Status: Beta — open for builders; under active testing. Formerly get_day_card. Most-tested tools remain get_birthdate and get_compatibility.

One calendar day in → the day card plus Roman / Greek / Norse day ruler context. Smaller than get_birthdate — day focus only.

One call returns the day’s cosmic card, weekday, and planetary ruler — a lightweight, deterministic lookup from a single date.


Input	`day_date` (YYYY-MM-DD) — required; pass the date explicitly (no implicit “today”)
Range	`1900-01-01` … `2100-12-31` → `full`; nearby dates outside that window → `extended`; farther out → `day_card_only` (day card + ruler still returned)
Version	`v0.3.0`
MCP URL	`https://mcp.geometry.app/mcp`

Ask:

What’s the day card for 2026-07-23?
