Answer:
It depends on which Eid you are talking about. Eid Al-Fitr comes after Ramadan, the holy month of fasting. Muslims have a small breakfast and then gather to pray Salah tul-Eid. Then, the usually go to many get togethers and just have fun and enjoy themselves.
Eid Al-Adha is celebrated in a slightly different way. After praying Salah tul-Eid, the men go (woman can go too, but they usually stay at home) and slaughter a goat, sheep, cow, chicken, etc. They may cook it that day, or keep it for later. Some give a portion of the meat as charity. Then everyone celebrates and has a good time.
In both Eids, most people wear new and beautiful clothes. They exchange gifts, especially in Eid Al-Fitr. Women will cook delicious foods, and everyone stays in a good mood.
InshaAllah this will help
