Install with npm
``bash`
npm install easter-date.js
or yarn:
`bash`
yarn add easter-date.js
To use the algorithms, import them into your JavaScript code:
`javascript`
// ES Modules
import { getWesternEaster, getOrthodoxEaster } from "easter-date.js";
`javascript`
// CommonJS
const { getWesternEaster, getOrthodoxEaster } = require('easter-date.js');
and pass the desired year as an argument:
`javascript
getWesternEaster(2024);
// Output: { day: 31, month: 3, year: 2024 }
getOrthodoxEaster(2024);
// Output: { day: 5, month: 5, year: 2024 }
`
