Rosh Hashana: Difference between revisions

#If one forgot [[Yaaleh VeYavo]] in [[Benching]] on Rosh Hashana during the day one does not have to repeat [[benching]], but during the nighttime one must repeat [[benching]]. <ref>Mishna Brurah 188:19 quotes the Magen Avraham 188:7 who says one doesn't repeat [[Birkat HaMazon]] and the Eliyah Rabba who argues and the Mishna Brurah leaves it unresolved. Shemirat Shabbat Kehilchata 57:7(4) quotes both opinions and in note 25 he concludes that one doesn't have to repeat [[benching]] because it's a [[Safek Brachot LeHakel]]. Similarly, [http://www.yutorah.org/lectures/lecture.cfm/764351/Rabbi_Hershel_Schachter/Inyanei_Rosh_Hashanah Rabbi Hershel Schachter in a shuir] (min 41-43) mentions that some achronim hold that one doesn't have to repeat [[benching]] because there is an opinion that one is allowed to fast on Rosh Hashana. When asked whether this would be considered Safek Deoritta Lechumra he explained that even if one forgot [[Yaaleh VeYavo]] one fulfills the Deoritta obligation of [[benching]] it just that one didn't fulfill the din derabbanan to have a meal for [[Yom Tov]]. </ref>
