Baruch Dickman asked:
Rav Kahana proves (top of 20a) that Adar can be 29 or 30 days. Doesn't his proof show that the same is true for Elul which disproves Rav on the top of R"H 19b who said that Elul was always 29 days?

The Kollel replies:
The conclusion above is that even Rav will agree that if needed, we make Elul 30 days.
