6504 —הבהרה על ספירת העומר וחגיגת חג השבועות מעבר לקו התאריך

Shalom u'Vrachah! [Summer 5718?]

The comment regarding Sefiras HaOmer, that it should not be like two Torahs, I did not merit to understand, for the Torah explicitly states that each individual must count on their own (as in 'uSefarah lah'—and not like the counting of Shomru), see Tosafos D"H uSefartem Menachos 65b, and to establish Shavuos on the fiftieth day. This is the only way to establish Shavuos (an individual count). The question is raised: if this is so, then one person will celebrate Shavuos on day forty-nine according to his count (since certainly he will not be exempt from counting), another on day fifty according to his count, and a third on day fifty-one according to his count! And there are many more questions about counting (lack of completeness, more than completeness, etc.). The Lechem Mishneh (chapter 7 of Lulav) brings this; this itself is its refutation. See there.

In my opinion, what you call in conclusion a 'great novelty,' the novelty is actually the simplicity of the matter—what is being taught here?

My letter in response regarding Tefillin surely arrived in due time. It was printed in Likkutei Sichos vol. 23 p. 327.

The comment regarding Sefiras HaOmer: as explained above in Igros vol. 6, letters reish-chet-tzadi and reish-tet-vav—that one who crossed the International Date Line during the days of counting must continue his own count and likewise celebrate Shavuos according to his own number.

Summary

The Rebbe clarifies that each person must continue their own Omer count even after crossing the International Date Line, which also determines when they observe Shavuos. This approach follows halachic sources and emphasizes individual responsibility in mitzvah observance.
