swedish-holidays

Library for calculating the date of all swedish holidays for any given year.

How to install:

$ npm install swedish-holidays

How to use:

const { getHolidays, getUpcomingHolidays, isHoliday } = require('swedish-holidays');

// Get an array of all holidays for the current
const holidays = getHolidays();

// Get an array of all holidays for a specific year
const holidays2019 = getHolidays(2019);

// Get an array of all upcoming holidays
const upcoming = getUpcomingHolidays();

// Check if today is a holiday
const isItAHolidayToday = isHoliday();

// Or if you want to check a specific date
const isThisAHoliday = isHoliday(new Date("2019-12-24")); 

The result will always be an Array filled with JSON formatted holiday information including name and date.

[
    {
        name: 'Julafton',
        date: '2019-12-24T00:00:00.000Z',
        day: 24,
        month: 12,
        year: 2019
    },
    {
        name: 'Juldagen',
        date: '2019-12-25T00:00:00.000Z',
        day: 25,
        month: 12,
        year: 2019
    },
    ...
]   

When using isHoliday the result is false if the provided date is not a holiday, otherwise it is the holiday JSON object.

Localization

If you want the holiday names to be returned using a different language than the default (Swedish), use the language JSON object and modify it before passing it to the getHolidays function.

const { language } = require('swedish-holidays');
const translation = { ...language };
// This value is 'Julafton' by default.
translation.christmasEve = 'Christmas Eve';

const holidays2019 = getHolidays(2019, translation);
// or if you want the current year
// supply a year that is 'falsy' e.g. undefined / null / 0 / false
const holidays = getHolidays(0, translation);

Limitations

This library can only return valid holidays for years between 1582 and 8702.

If an invalid year is requested, some holidays will be missing.
