# eluna

[![eluna build status](https://github.com/bebyx/eluna/actions/workflows/rust.yml/badge.svg?branch=master)](https://github.com/bebyx/eluna/actions/workflows/rust.yml)
[![eluna crate](https://img.shields.io/crates/v/eluna)](https://crates.io/crates/eluna)

A Rust translation of [Minkukel's algorithm](https://minkukel.com/en/various/calculating-moon-phase/), which is claimed to provide **lunar data for a period of 1900-2100**.

Input is a timestamp (`i64`), whether positive or negative. It's compatible with
[chrono `timestamp()`](https://docs.rs/chrono/0.4.19/chrono/struct.DateTime.html#method.timestamp) function.

Outputs are raw (moon second for the given time), fraction of the moon, a moon day, and a phase (numeric or English).

Results are rather precise, when close to 2000, but may be quite approximate for the distant dates.

## Install

Add this line to `Cargo.toml` to include **eluna** as a dependency:

```toml
eluna = "0.1"
```
