(R. Elazar citing R. Chaninah): It once happened that 24 wagons of students of Beis Rebbi came to extend the year in Lod. The evil eye attacked them and they all died at the same time. At that time, they transferred the location of the Ibur Hashana from Yehuda to the Galil.

They wished to remove from Yehuda even the announcement made after the Ibur Hashana. R. Simon told them - Don't you even allow any remembrance of the Ibur Hashana in Yehuda? Don't we find that in Ba'alas in Yehuda they sanctified the year?

This place Ba'alas is sometimes described as part of Yehuda and sometimes one of the cities of Dan. Alsaka, Givson and Ba'alas are from Dan; Ba'alah, Iyim and Etzem are cities of Yehuda.

Question (R. Yirmiyah to R. Zeira): Isn't Lod part of Yehuda? R. Zeira agreed that it is. So why can they not do Ibur Hashana there?

Answer: Because they are haughty and they do not know a lot of Torah.

R. Zeira turned away and saw R. Acha and R. Yehuda ben Pazi. He told R. Yirmiyah - you have made me disgrace the Rabbis. (You should have not asked me your question as you knew that they were coming.)

There are three signs that cause the Sanhedrin to extend the year - the spring (that it is the time of the late rains and the crops have not yet ripened, which will cause Pesach to fall before the spring begins), the winter season (if it continues until a point that the 16th of Nisan will fall out in the winter season) and the fruits of the tree (so that if they have not grown yet, they will grow on Pesach)

They extend it if two of these signs occur, but not for only one, but if they did extend it for only one, it is valid. If 'the spring' was one of the reasons, they would be happy (as the prohibition against consuming the new grains before the bringing of the Omer would not extend too long by adding a month, as they did not fully grow yet, so they anyway would not have been able to eat them yet.

(Rabban Shimon ben Gamliel): They are also happy if one of the reasons is that it is the winter season.

They extend the year if the reasons apply in the following three countries - Yehuda, the Transjordan and the Galil. For two of them they extend but not for one of them, and if they did, it is not valid. And if Yehuda was one of them, they were happy because they brought the Omer offering from the barley of Yehuda.

They may not extend the year merely because of the cold and the rains but if he did, it is valid. They may not extend because of kids (that they are not old enough to be used for the Pesach offering), chicks (that they are not old enough to be used for bird offerings), or milk (which is not ready yet). But these reasons are enough to be a support for extending the year; and if these reasons were used (mistakenly) to extend, it is valid.

(R. Yannai): Rabban Gamliel used to say - If the kids were young and the chicks were small (that is a reason enough to extend the year) - it is correct in my mind and in my colleagues' minds that this year should be extended by 30 days.
