Reply To: Shabbos Hagadol, The Great Shabbos

In the gemora in Pesachim everyone agrees that at least 14 days before one should learn Hilchas Pesach and Shabbos Hagadol would be less than that. Bayum Hahu encourages zerizim, mivod yom, in the day time but that only apples bizman chiyuv, at the time being responsible which when matzah and maror is in front of us to be able to talk about it. The Massei Hashem explains that the question of doing it earler only applies on the one not questioning as it does not make a difference when we speak about yetzias mitzraim but for others it is obvious that we need something to question about.
