Isdays is an annual event and the culmination of MOSAIC's work programs. This year's isdays will be themed "Guide the Wave of Millennipreneurs in the Halal Industry." This theme aims to motivate participants and provide them with the necessary education, inspiration, community, and support for young Muslims in developing the halal industry.

The event features Islamic activities that will undoubtedly benefit participants, including a grand religious gathering (tabligh akbar), a grand religious gathering (karimah akbar), Islamic competitions such as Muslim preachers, posters, and Islamic video content creation, as well as talk shows and events featuring inspiring guest stars. It is hoped that this event will unite young Muslims in an activity that can foster strong bonds among participants. Participants are expected to develop their communication skills and creativity in creating posters, videos, and communicating in the Muslim preacher competition. It is well known that most young people are still considered lacking in public communication and lack creative thinking. Therefore, this competition is expected to prepare young people to practice public speaking and creative thinking, thus indirectly helping and contributing to preparing quality education for the sustainable development of SDGs 4.

Additionally, a bazaar will be held at the event, with four categories: fashion and lifestyle, food and beverage (F&B), books, and community. The bazaar is intended for local brands, prioritizing local brands and not resellers. This event can also serve as a marketing platform for MSMEs to the wider community attending, indirectly contributing to economic growth by advancing existing MSMEs. Therefore, this can be a key driver of economic growth in SDGs 8 (Decent Work and Economic Growth).
