Question
Do we wear a Kittel for Rosh Hashanah or only for Yom Kippur?
Answer
A Kittel is worn in the synagogue by most men on Yom Kippur, some on Rosh Hashana (in all communities the ones who lead the services does, in some everyone does) and some on neither!
I suggest you follow the custom of your family and if you do not know it follow that of your congregation.
