Thank you both for your comments. For your information, Duaa, the celebration of New Year is not a Christian celebration of the birth of Jesus. That would be Christmas, for Christians. For most people in my country, the New Year celebrations don't have a religious character at all. Thank you for commenting, though.

indeed, I agree with my sister Mumtaz, and thus doesn't mean that we don't honer Jesus's birth,, but we believe that both prophets Jesus and Muhammad will be proud of us if we follow their teachings instead of celebrating their birthdays :) Kind Regards FJleert :)

I just wanted to add something FJleert. Honestly we don't celebrate the new year where I come from, for us it's more of a tradition that came from the west, but as an Eastern society in the Islamic/ Arab world, we don't celebrate the new Gregorian year, and we shouldn't even celebrate the new Hijri year (Islamic calendar), so for us it's just another day. I said this, to tell you that we -in general- in the Arab world, won't feel offended if people didn't congratulate us for the new year, yet it stays as a private matter if you wished to congratulate your friends from this part of the world, as you do with your friends from the Netherlands :) I wish you happy times always.
