1) How does this calendar align to the phases of the moon? How many moons are there per-year? Is this variable? This is important due to archaic calendar systems and dates that are based on solar-lunar calendars (e.g. China & Japan)
2) Is there a quick and easy algorithm for re-mapping dates? My birthday was on Mar 30, 1991 - for example. Would I simply keep the old date, or adopt a new one? I assume keep the old since its still on the calendar, but what about people born January 31st?
3) How do seasons align and fluctuate along these new datelines? And how does this floating week influence it?
