Quick Examples

ES Modules (Typescript/Javasript)

The prefered whay is to directly import the typescript module. However, you can also use .js. Please find here some examples and full api here.

import { getHolidays, isHoliday, isSpecificHoliday } from 'feiertagejs';

const today = new Date();

// is today a holiday?
isHoliday(today, 'BW'); // false --  probably false, because you are working ;)

// check if a day is a specific holiday
isSpecificHoliday(today, 'CHRISTIHIMMELFAHRT', 'ALL'); // true | false

// get all holiday for a single year: getHolidays()
// returns an array of "Holiday" Objects. Please see the docs.md for all properties.
const holidays2023 = getHolidays('2023', 'BUND');

holidays2023[0].date // === Date("2023-01-01");
holidays2023[0].name // 'NEUJAHRSTAG' (constant)
holidays2023[0].translate('de') // German translation: Neujahrstag
holidays2023[0].equals(date) // Compare days only (ignore time)

One entry of the array contains:

[{
    name: 'CHRISTIHIMMELFAHRT',
    date: new Date('2023-05-17T22:00:00.000Z'),
    dateString: '2023-05-18',
