1,200. Taking the Lulav on Shabbos

Hilchos Shofar, Succah v’Lulav 7:16

When the Temple was standing, the lulav was taken even when the first day of Succos fell on Shabbos. The was true even in other lands so long as they were sure that this day was observed as a holiday in Israel. Places that were far removed from Jerusalem would not take the lulav on Shabbos because of the doubt regarding the date of the holiday.

Hilchos Shofar, Succah v’Lulav 7:17

When the Temple was destroyed, the Sages prohibited taking the lulav on the first day of Succos that fell on Shabbos even for residents of Israel who had sanctified the new month (and therefore had no doubts about the date of the holiday). This was done out of concern for the residents of distant inhabitations, who would not be aware of when the new month was declared. Rather than having some people take the lulav on Shabbos and others not, a standard practice was instituted. The obligation to take the lulav on the first day of Succos applies equally in all places and there is no longer a Temple to explain why different places should have different practices.
