The Shulchan Aruch (Orach Chaim 458:1) based on a Yerushalmi, states that some people have the custom to bake their matzos for the seder on the afternoon of erev Pesach, namely, the same time that the korban pesach was being prepared. The Chidah (Moreh B&rsquo;etzbah 7:205) writes that whilst baking these matzos, one sings the hallel, to commemorate hallel which was said whilst preparing the korban pesach. Beis Chernobyl even say the berachah over this hallel. (Piskei Teshuvos, volume 5, chapter 458, footnote 4) <span style="mso-spacerun: yes;">&nbsp;</span></span></span></span></p>

The answer is 3 Teves. When there are 29 days in Kislev, the 8th day of Chanukah will be on 3 Teves and so hallel will be said. If however, there are 30 days in Kislev, then 3 Teves will be the day after Chanukah and tachanun will be said.</span></span></span></p>

In the past, there were visitors who would eat their meals in the shul and for this reason, kiddush was instituted in the shul service. This was based on the principle that one has to eat one&rsquo;s Shabbos meal at the same place as one makes kiddush and since these visitors were eating in the shul, the shul kiddush enabled them to fulfil the mitzvah of kiddush. (Shulchan Aruch, Orach Chaim, 269:1) However, there is also a downside to this shul kiddush, since some people eating their meal at home, may mistakenly think that having heard kiddush in shul, they do not have to make it when they return home. </span></span></span></p>
