There was no Shabbos Chanukka in 1948. WHAT???? Yup. Chanuka started late that year, so Shabbos Chanuka started in January 1949.
In 2005 we had only 6 days of Chanukka. Two days went into 2006.
We had two Shabbos Chanukka’s last year (2009), but not for the same reason. But even that won’t happen again for another 17 years.
