Question
I've heard the first prayer on Yom Kippur is Kol Nidrei. Why is it important?

Question
Why is the shofer not blown on Rosh Hashanah when it falls on Shabbos. I've heard that the Shofar is considered Muksah, and I've heard to prevent one from carrying on Shabbos. I think there are more deeper reasons.

Question
regarding the promise that Hashem will refund you the money spent for food for shabbos and yom tov, does that also apply to chol ha moed or no. also, does he refund you only for kosher food eaten on shabbos, or does He refund you for non-kosher food as well. thanks a lot.

Question
It is customary to study Torah on Shavuot night. Does it make any difference what a person studies?

Question
Dear Rabbi, Why is Shavuot only one day (two in the Diaspora) as opposed to Passover and Succot? Isn't it a very inportant celebration of giving us the Torah? Thanks
