HolidaysCalendar

This is a container library for retrieving the holidays' calendar of a locale.

You can use it as a Node.js module or in browser, but you must extend it with your "localized" calendar or use it together with an available locale-module (like holidays-calendar-brazil).

Instalation

If you use NPM, then you can install it with npm install holidays-calendar. Othewise, you can download the latest release and use it in your browser or in other Javascript-based projects.

Creating a localized calendar

In order to create custom calendars, you must have Node.js installed. Inside src directory, there's a CSV spreadsheet file called holidays.csv. Change its content accordingly to your needs, keeping the same column scheme and date formats. Then run:

gulp generate --name

... where --name is your locale identificator. This will generate a new holidays-calendar-identificator module inside dist folder. There's a sample customization for the Brazilian Holidays Calendar, which happens to be the source code of the holidays-calendar-brazil module. It would be awesome if you could your custom calendar into the NPM repository.

Usage

Node.js

var calendar = require("../dist/HolidaysCalendar-brazil");
console.log('The total number of holidays in 2020 is '+calendar.Year(2020).total);

Browser

<script src="../dist/HolidaysCalendar.js"></script>
<script src="../dist/HolidaysCalendar-brazil.js" charset="utf-8"></script>
<script>
console.log('The total number of holidays in 2020 is '+HolidaysCalendar.Year(2020).total);
</script>
