Frank, Sorry, just after sending my first answer on this question I found a mistake in my argument. The date by the Sun calendar is irrelevant! According to the ecclesiastical definition, the Easter is the first Sunday after SOME full moon. Therefore the time interval between a full moon and Easter is between 0 and 6 days. (Any number of days has equal probability). As at the full moon the distance is 180, and the motion is 12 degrees a day, the minimum distance is 180-6.12=108, and the maximum is 180 (if the full moon and Sunday happen on the same day). Thus the average distance is 144. Alex.
