Mother's day, Hari Ibu, is celebrated nationally on December 22. It is the day of the first Indonesian Women Congress (Indonesian: Kongres Perempuan Indonesia) from December 22 to 25, 1928. The meeting happens in a building called Dalem Jayadipuran now functioned as office of Center of History and Traditional Values Preservation (Indonesian: Balai Pelestarian Sejarah dan Nilai Tradisional) in Brigjen Katamso Street, Yogyakarta. It was attended by 30 feminist organizations from 12 cities in Java and Sumatra. In Indonesia, feminist organizations have existed since 1912, inspired by Indonesian heroines of the 19th century, e.g. Kartini, Martha Christina Tiahahu, Cut Nyak Meutia, Maria Walanda Maramis, Dewi Sartika, Nyai Ahmad Dahlan, Rasuna Said, etc.
The idea to make the day official was started during the third Indonesian Women Congress in 1938. It was signed by president Soekarno under the Presidential Decree (Indonesian: Dekrit Presiden) no. 316 year 1959. The day was originally aimed to celebrate the spirit of Indonesian women and to improve the condition of the nation. Today, Mother's Day is celebrated by expressing love and gratitude to mothers. People present gifts to mothers, such as flowers, hold surprise parties and competitions such as cooking competition or kebaya wearing competition. People also allow mothers to have their day off from doing domestic chores
