더캘린더 The Calendar is a lifestyle app that provides information on events in the metropolitan and regional areas. It operates as a platform connecting event information suppliers and users. The aim is to promote democratization of information by bridging the information gap between experts and the general public. The goal is to provide an average of 100 event information per day.

This app offers free promotion opportunities for event information suppliers. While the success of events often depends on the number of interested participants, opportunities to advertise are often limited. On the other hand, it provides event information to users in advance, enhancing their quality of life by offering participation opportunities. Before, the ordinary citizen would only find out about an important event through news articles after it had already taken place. This service aims to alleviate such mismatches between the two parties.
