Two major festivals of Muslims

I am a Muslim. The two Muslims in our country you described are called Eid al-Fitr, Eid al-Adha and Eid al-Adha. Today is Eid al-Fitr. When I first arrived abroad, foreigners sent me a congratulatory message, and I haven't reacted yet. In fact, EID and what we call Erdi are probably transliteration of Arabic.

Eid al-Fitr is a holiday after Ramadan. On that day, Muslim men will go to the mosque and then to the cemetery. Rich people also give money to others.

70 days after Eid al-Fitr is Eid al-Adha. Our tradition is that animals, cows or sheep must be slaughtered on this day when economic conditions permit (I have never killed any other animals in my family).
