Kartini Day is a holiday celebrated in Indonesia on April 21st each year. It is named after Raden Ajeng Kartini, an Indonesian national heroine and pioneer in the field of women's rights. Kartini was born on April 21, 1879, in Central Java during the Dutch colonial period.

 Kartini was an advocate for education and women's rights in Indonesia, and she worked to promote equality between men and women. She is known for establishing a school for women, which was uncommon at the time, and for her letters, which were published after her death and became a source of inspiration for Indonesia’s women’s rights movement.

 Harmoni Group also supports Kartini Day by contributing to the use of traditional clothing on Kartini Day to remind people of Kartini’s struggle for women in Indonesia, and also Harmoni Group always strives to improve the welfare of its female employees.

Harmoni Group empowered the quality of female employees by prioritizing gender equality and providing equal rights to female employees. With this things, Kartini’s sacrifice will always be alive and we can implement it in our daily work activities.
