Tried to install some spamware and quit. This app appears to have been hijacked, which is sad because it used to be great. Looks like I'll have to try and download an older version.

Im changing my review. It is an awesome app. The widget works and It has awesome calenders including mayan, Egyptian(coptic), etc. For suggested future calendars put the [Celtic Tree Calendar], may be the [Hindu], and [Buddhist Calendars]. Some calendars from other ancient Calendars like [Babylonian(nabonassar)], [Greek] etc. And maybe some fictional alien calendars. Also there is a modern pagan calander called the [goddess calendar] that I think would be cool.

This app is awesome, I think the Hindu calendar is relevant enough to be included tho, and also unix time should probably be easy to implement, lol
