But as a rule, generally, there is a large number of them that can agree on one date for their festivals. I mean you ask most Christians when christmas is and they will say Dec 5th... even easter, that moves, has a rule as to when it is (all be it based on a pagan formula).

In the UK Pagans are trying to get the Pagan festivals recognised as religious dates so they can book them off for holiday, but you ask someone when Imbog is... even if they call it Imbolg.. or is it Imbolc, Oilmec (is that right?)... what about Ostara, or Oestra?

Personally I am happy for it to be really free flow and not be "recognised" but I know others do, and if they do, they need to find a way to agree on some stuff.
