25, Rosh Hashanah is the Jewish New year and a more upbeat celebration. There is also shavuot which is the celebration of Moses receiving the ten commandments on Mt. Sinai....
Other than that we celebrate coming through times of trial and tribulation in our holidays....
FIB, Happy Chanukah buddy. I have my kids this year, but it is still the same feelings. We have always celebrated both Holidays as my wife was Baptist. Not having your family intact is difficult either way my friend. As crazy as it sounds I cried tonight as my kids opened their gifts, I am sad that their mother does not get to share in this the way we always have.... They don't deserve this......
I hope you can take advantage of your time and try and do something for yourself my friend.
