How are you differentiating between the day?
There are different versions to the story and the date that it happened. In both 1860 and 1869, Yom Kippur was a Wednesday. According to the Chofetz Chaim, it happened in 1848 which was a Shabbos and also during the pogroms of Chmelnitzky and Tach v’Tat-1848-1849. This date also when the Avnei Nezer was almost 9 (5609/1848) and he was young as well in 5606/1845 when Yom Kippur also came out on Shabbos.
SO it’s interesting to wonder whether R Salanter was making kiddush in Vilna on the very same day that the future Avnei Nezer was refusing to in Bedzin, 500 miles away!
Dunno.
