Firstly, there is no reason to name your child according to his date of birth. There is no such practice in Islam, and it may fall under fortune-telling which is prohibited in Islam. Just choose any name that you like that has a good meaning.
As for Yusha, there is nothing wrong with it being a Jewish name. The prophets Yaqoub (Jacob), Yusuf (Joseph), Musa (Moses), Harun (Aaron), Zakariyyah (Zachariah), Yahya (John) and Isa (Jesus) were Jewish.
Yusha is the Arabic word for Joshua, a good man and a companion of Prophet Musa (Moses), whose name means "God is salvation", which is a good meaning.
Yusha is an acceptable name for Muslims. The only issue is that since this name is mostly used by Christians and Jews, people may think your child is Christian or Jewish. However, if Yusha is a common Muslim name in your area, then there wouldn't be a problem.
