A Very Boethusian Shavuos
But this is not what I want to write about - what I am curious about is how did this theoretical arguement play out in practice during the time when the Temple stood? I mean, I don't think it was possible for the two groups to celebrate the chag on different days in the Temple. So what happened? Was it a situation that when the Pharisees controlled the Sanhedrin, the chag would be celebrated by their calculations, and vice versa when the Sadducees were in charge? Does the fact that most of the Sadducees came from priestly families have anything to do with what happened?
What did the group that was not in power do in those years? Did they acquiesce and celebrate along with their opponents in the spirit of "eilu ve'eilu"? Or did they figure it was better to not celeberate at all than celebrate at the wrong time?
