From Joules Media B.V.:
We're introducing yearly subscriptions. Get ongoing access to all available calendars, including automatic updates, lots of extra info and (live) sports results, right inside your calendar app. Take the one-month free trial first, so you can try before you buy. And if we can help you with any questions you have, we'd be more than happy to! Just drop us a line at email@example.com or tweet us @SchedJoules.
