When is Pope St. John XXIII's feast day?

Seems to be some confusion over 3rd June or 11th October. Thanks in advance!

11 October (Catholic Church)
4 June (Anglican Church of Canada, Episcopal Church and Evangelical Lutheran Church in America)

October 11 is the feast day, remembering the commemoration of the opening of the Second Vatican Council on October 11, 1962 by him. June 3 is the anniversary of his death.
