Wiccan Moon is an easy way to keep track of which of the year's moons is coming next. Every month has a specific moon associated with it in many different belief systems.
There are many variations throughout differing branches of Pagan belief, this application shows one of the more popular Wiccan naming conventions as follows for each month's moon from January to December.
Long Nights Moon
Once every few years there may be two full moons in one calendar month and a rare Blue Moon will also appear.
The current moon phase and location (in the zodiac) is shown along with a graphical representation of its phase.
Below that, a simple countdown in days and hours to the next full moon along with a different symbolic picture of the moon that is coming.
When it's a full Moon the countdown remains at 0 days 0 hours until the full Moon's time is over and has moved to a Waning Gibbous and the new countdown begins. This is by design.
