Thanks for the report @jppcel! I can reproduce this issue in Firefox 55 and Safari for OSX.

The calendar works as expected in Chrome and Edge.

The reason is given right in the console as a clear warning:

Deprecation warning: value provided is not in a recognized RFC2822 or ISO format.
moment construction falls back to js Date(), which is not reliable across all browsers and versions.
Non RFC2822/ISO date formats are discouraged and will be removed in an upcoming major release.
Please refer to http://momentjs.com/guides/#/warnings/js-date/ for more info.

That is, they're passing non-standard date-formats to moment.js, like "1-01-2017" and "2-01-2017" (from their data-month attributes in the HTML). This will simply feed the values into new Date() and that will only work on whatever browser happens to understand that format (which for their strings is Chrome).

So this is technically the site's error. If they change their data-month values to a format that moment.js intrinsically understands, then they will have no problem (such as "2017-01-01" and "2017-02-01").

(Also note that Firefox bug 1274354 is about tracking what compat work to do to resolve this data-parsing mess.)
