Wishing everyone and those who celebrate it a good Eid al-Adha, or, in English, the Festival of Sacrifice. Big thank you to @unicornio for helping me make this thread!
What is the purpose of Eid al-Adha? 
Eid al-Adha, an Islamic holiday, is one of the two major festivals of its kind in which it celebrates the prophet Ibrahim and his willingness to sacrifice his son in order to show his obedience to God. Within the passage, Ibrahim is depicted to be stopped right before he did so and given a sheep to sacrifice instead. In effect of this, during Eid al-Adha sheeps, cows, lambs, and goats are often sacrificed and eaten on this holiday. This meat is also used to feed the poor and needy and is done as an act of selflessness. The festival in itself is assorted with many types of foods and such; but the specifics are more guided by where you live. (In example, if you live in America then these celebrations usually just have the typical American food.)
Traditions, Food, and Customs!
The other festival, Eid al-Fitr happens after Ramadan and is a one day Eid where they do two activities in that day. This festival, Eid al-Adha is a three day Eid where they do multiple events organized by their community.
One or two days before the Eid, inside a venue or outside they give zakat, which is giving food and/or money to those who need it. This is a religious duty for all Muslims who meet the criteria of wealth. This must be given before the Eid prayer, in which it is considered Zakat al-Fitr, but after such it is just considered ordinary charity. The day begins by doing their mandatory prayer in the mornings at about 8:30 AM. In regards to prayer, all prayers for the Eid have to be done before the Dhur/Thuhr prayer (fourth prayer of the day that is done in the afternoon). The rest really differentiates depending on where you live and your usual customs. In regards to America or western countries in general, during Eid al-Adha Muslims usually go out for breakfast; their afternoons featuring a huge cookout/picnic at the park. At the end of the day they rent out a venue and have a party. As said before, it usually hosts the typical American food such as burgers, pasta, hotdogs, and etc. Desserts are the same with cake, pies, and other pastries/sweets. During parties, the duff is usually played (but only during ceremonies). The parties are also often separate between opposite genders, so girls and boys are often in separate parties.
This event is also a great time for reconnection as Muslims also usually take this time to call distant family members and send them gifts and well wishes.
Taking time to appreciate other cultures, religions, and celebrations is important, so I hope this mini-appreciation thread did it justice!
