Non-Muslims do not fast, but it's considered rude for them to be seen eating during fasting hours. Imagine visiting your parents or grandparents, your aunts and uncles, your friends, and everyone on your street, and at each house eating a cookie or a snack or a small meal. That's what it's like. This is the time of year when many people return to their home town or village to see their parents and extended family. Schools let out.
Children get a new suit of clothes.
The house gets a new coat of paint. The atmosphere is friendly. The second major holiday is Idul Adha. Moslems believe this commemorates the day that Abraham was about to sacrifice Ishmael to Allah but was stopped at the last minute. The Bible describes in Genesis 22 how God tested Abraham by asking him to sacrifice Isaac, but stopped him at the last minute, convinced of his commitment.
