Through April there are exhibitions, fireworks, song and dance events, athletics competitions, Juche idea seminars and visits to places connected with Kim Il-sung's life,[3] including his birthplace in Mangyongdae.[2] Some of these events take several days. Foreign art groups and dignitaries are invited to visit North Korea during this time around the day itself known as Sun Festival.[3] The annual Kimilsungia Festival[3] (held since 1998[19]) and the April Spring Friendship Art Festival (since 1982)[20] are also held at around the time of the Day of the Sun. The latter typically features foreign performers from some 20 countries whose televised performances are an anticipated and well-liked rare glimpse of foreign culture for North Koreans.[21] It also includes the Pyongyang Marathon.[22]
