# get_day

> BETA — One calendar day → day card plus Roman / Greek / Norse day ruler.

<Badge color="orange">Beta</Badge>

<Info>
  **Status:** Beta — open for builders; under active testing. Formerly `get_day_card`. Most-tested tools remain [`get_birthdate`](/tools/get-birthdate) and [`get_compatibility`](/tools/get-compatibility).
</Info>

One calendar day in → the **day card** plus Roman / Greek / Norse **day ruler** context. Smaller than [`get_birthdate`](/tools/get-birthdate) — day focus only.

<Info>
  **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`                                                                                                                                             |
