LITE The LITE edition works for dates before the end of 2008 and it's made for you to try it before buying the full version.

Perpetuum is the Revolutionary Lunar Calendar for the iPhone and iPod touch.

If you're like us, you don't like reading dates and numbers from a table and then try to figure out how many days you have until the next new or full moon. Perpetuum solves this problem and gives you the information you need in a way we couldn't find anywhere else.
