That's how it's defined. In old times, they did not even had a calendar. they just looked at the skies and when the moon was empty, it was decided as a new month. http://ayende.com/2333/by-foul-moon#comment5http://ayende.com/2333/by-foul-moon#comment5Sat, 28 Apr 2007 06:12:08 GMT@Ken, Using the Hebrew calendar would be too easy... :-) Regardless, is it guaranteed that 15th of a month is full moon? http://ayende.com/2333/by-foul-moon#comment4http://ayende.com/2333/by-foul-moon#comment4Fri, 27 Apr 2007 21:53:40 GMTreturn Moon.Capacity == Moon.Length seriously, you can use Hebrew Calendar and check for day==15 def IsWitch: return hasBroomstick and UsesBoo() http://ayende.com/2333/by-foul-moon#comment3http://ayende.com/2333/by-foul-moon#comment3Fri, 27 Apr 2007 21:29:37 GMTWhere are the unit tests?
