The official website for the "Days in the Dioceses" of the 2027 Seoul World Youth Day will launch on the upcoming Easter Sunday (April 5). This marks the opening of a communication channel to promote the event and accept future registration applications. The start date for registration will be announced on the website.

The Preparatory Committee for the 2027 World Youth Day Days in the Dioceses held its 7th meeting on February 25 at the Catholic Bishops' Conference of Korea in Junggok-dong, Seoul, where they shared these updates. The meeting was attended by the committee chairman, Bishop Kim Jong-gang (Bishop of Cheongju), along with committee members and executive officials from the Bishops' Conference, dioceses nationwide, and religious institutes.

The Days in the Dioceses (DID) is a preliminary event held in 15 dioceses across the country, excluding the Archdiocese of Seoul, which will host the main World Youth Day events. It provides a meaningful time for young people from around the world to stay in various dioceses, experience unique local cultures, and interact with Korean faithful. The 2027 Seoul World Youth Day's DID will take place from July 29 to August 2, followed by the main WYD events from August 3 to August 8.
