This is according to the Gregorian callendar. Rabbi Kahane (may G-d avenge his blood) was murdered on Novemeber 5, 1990. It is not a Yarzheit though, because Rabbi Kahane was murdered on the 17th of Heshvan, 5751. Today is the 7th, so the Yarzheit is 10 days from now. But I thought our Gentile friends would like to know.
