I ask this question because, I live in a city where I dont know any Muslim around me but only Christians, and my father is a Muslim but he lives far away from my home and I live with my Christian mother. I dont know how to celebrate Eid Al Adha and Eid Al Fitr myself.

So, can someone please tell me whether it is obligatory or just Sunnah to celebrate them? Because, I dont want to make a mistake and fall into disbelief if I havent celebrated them.
