I stumbled upon this app from a description on the author's site. I'm glad he made it.

A little more interactivity would be nice, should a v2.0 come out. A month view perhaps or a translator for gregorian to look up dates.

The tranquility calendar is a clever concept. Could be used in schools to teach in all kinds of ways.
