Rosh Hashana 4:2-3

Rosh Hashana 4:2

Jerusalem had an advantage over Yavneh in that residents of other cities who could see and hear Jerusalem, and who were close enough and could get there, could also blow shofar on Shabbos, but in Yavneh they only blew shofar in the court.

Rosh Hashana 4:3

Originally, the lulav was taken in the Temple all seven days of Succos and elsewhere just the first day. After the Temple was destroyed, Rabbi Yochanan ben Zakkai instituted that it be taken everywhere for all seven days in remembrance of the Temple practice. He also instituted that eating the new grain be prohibited the whole day on which the omer barley offering would have been waved in the Temple.
