BZ posits a very interesting political and religious question in his post about Jerusalem and when and how long to celebrate Purim in the modern city.
This isn't an issue for the Reform Jew for she celebrates a single day of the Holiday. She joyously engages in Sukkot for seven days, spends one day in prayer and introspective thought during Rosh Hashanah and takes Lactaid for one night of Shavout. However when it comes Chanukah, she lights the candles for all eight nights. Why?
I could guess it has to do with American culture of the "Holiday Season" or perhaps it is lack of education. However an academic and thoughtful answer would be nice...
Rabbis? You got something?
