The Marian Days (Vietnamese: Đại Hội Thánh Mẫu, officially các Ngày Thánh Mẫu) is the main festival and pilgrimage for Vietnamese American Roman Catholics. The annual event in honor of the Blessed Virgin Mary has taken place the first weekend in August since 1978 on the 28-acre (110,000 m2) campus of the Congregation of the Mother of the Redeemer (CRM) in Carthage, Missouri. Tens of thousands of attendees come from throughout the United States, while non-Vietnamese locals and some visitors from Canada, Vietnam, and Australia also attend.
