I was in Israel during Hanukkah. It is a time when children are on vacation from school, and along with Sukkot and Pesah, it is one of the three week-long vacations that Israeli schoolchildren can count on.
One of the things that makes Judaism work better in the Jewish state than in the Diaspora is that the public calendar reflects the Jewish calendar. So the opportunity to celebrate Hanukkah or any other holiday can be suitably joyous or solemn.
But even completely secular Jews in Israel (perhaps accounting for 40% of the country) are tuned into the Jewish calendar for precisely this reason.
Just one of the reasons that I am a Zionist.
