Yom T’voach: Technicality or Principle?

What lies behind the observance of יום טבוח after Shavuos? Is it simply due to a lack of time to bring the korbanos on Yom Tov—or does it reflect a deeper halachic position?The Alter Rebbe’s surprising assertion that even בית הלל followed this practice raises a fundamental question: what is his source, and why would בית הלל align with בית שמאי?Through a careful analysis of the Rebbe’s sicha—engaging the approaches of Rabbi Zevin and Rav Chaim Naeh, and clarifying its flow and key דיוקים—we uncover a novel interpretation rooted in מסכת ביצה. The result: יום טבוח emerges not as a technicality, but as a deliberate expression of שיטת בית הלל.לקוטי שיחות, חלק כח, חג השבועות
