Eid is known in Indonesia as Idul Fitri (or more informally as Lebaran) and is a national holiday. Idul Fitri is the biggest holiday in Indonesia. Shopping malls and bazaars are usually filled with people days ahead of Idul Fitri, which creates a distinctive festive atmosphere throughout the country, along with traffic mayhem. Many banks, government and private offices are closed for the duration of the Lebaran festivities.
In Indonesia, it is common during this period for people to engage in "mudik" activity. It is an annual tradition that people in big cities such as Jakarta, Surabaya, or elsewhere, travel to their hometowns or other cities to visit relatives, to request forgiveness, or just to celebrate Eid with the whole family. The government of Indonesia has prepared the transportation infrastructures to accommodate a huge amount of travellers by repairing damaged roads and bridges. However, the impact is still tremendous as millions of cars and motorcycles jam the roads and highways, causing kilometres of traffic jams each year.
When celebrating Eid, It is common to greet people with "Selamat Idul Fitri" or "Salam Aidilfitri" or "Selamat Hari Raya"(in Malaysia) which means "Happy Eid". Muslims also greet one another with "mohon maaf lahir dan batin" in Indonesia and "maaf zahir dan batin" in Malaysia, which means "Forgive my physical and emotional (wrongdoings)", because Idul Fitri is not only for celebrations but a time for atonement: to ask for forgiveness for sins which they may have committed but was cleansed as a result of the fasting in the Muslim month of Ramadan.
In Indonesia there is a special ritual called halal bi-halal. During this, Muslim-Indonesians visit their elders, in the family, the neighbourhood, or their work, and show respect to them. They will also seek reconciliation (if needed), and preserve or restore harmonious relations.
