Eid is a holiday for Muslims to call it Eid and the momentum of mutual forgiveness, after the fasting of Ramadan which cleanses the soul, cleanses sins of the past day.
In Idul Fitri it means returning to nature. The word fitrah of the fitri word is sacred. Muslims celebrate Eid al-Fitr after 1 full fast and on that day Muslims welcome victory after 30 days of fasting.
Eid al-Fitr as a return to nature, namely the origin of human events that are pure from sin, like newborn babies in the world.
