The Gemoro says that we do not need to keep Sukkos on the 14th of Tishrei in case Av and Ellul were only 29 days, because in that case there would have been two months of 29 days and that would have been heard by everyone. [I assume that the Gemoro is talking about for places where shluchim never reach, or take longer than a month to reach]

Rashi talks about Pesach and the months of Shevat/Adar being both 29 days for some reason, and says (if I understand correctly) that Teves is anyway only 29 days, so that in fact there are 3 months running that are only 29 days, and that is so rare that everyone would have heard this.

I have two questions:

1) If this is the pshat - why does the Gemoro say that everyone would have heard of TWO months, rather than THREE months of 29 days

2) I am confused that the Gemoro is presumably talking about the time when they were MeKadesh Al Pi Reiah - in which case Teves might not have been 29 days! (I find this generally confusing in this perek when the Gemoro is talking about the era when they were MeKadesh Al Pi Reiah and when not, and what all the fuss about MeAymim the witnesses is!)

Maybe you can shed some light (excuse the pun) Thanks
