# Note:

This library is a more or less direct port of the [Fourmilab Calendar Converter](http://www.fourmilab.ch/documents/calendar/), just extracted from the DOM.

# Testing

A crude test suite is in place, consisting of basic [jasmine](http://jasmine.github.io/) test cases for the astro package and the Bahai calendar.

Currently it is not suitable for production usage. YMMV.

To run the test suite, you need node.js, npm and bower installed.

Then type the following:

```shell

bower install

npm install

```

Open the page test/index.html in your favourite web browser.
