Geordie thinks they fasted both days. I agree that it probably was not everyone who fasted both days (and that may be what Geordie meant as well – he was probably just explaining what the ones who did fast 2 days did). I don’t know how many did that – it may have just been a few people and that may explain why you didn’t know about it. Oh, I see you wrote “most people didn’t fast two days”, so we don’t disagree about that.
“My disagreement with Geordie13 is what day they davened and fasted for Yom Kippur.” Thanks for explaining, and thanks for explaining the technical details of the machlokes.
Is it possible that some people kept Y”K the first day and others kept it the second since there were 2 different opinions?
