The ceremony held July 26, 1963 (lunar calendar, June 6), at the former church headquarters in First Street, Chung-Pa Dong.

After True Father explained "The Day of All Things" as the day of hope that God has been longing for as he guided the long history of restoration, he conducted the "Hen-Gong" ceremony, when the all things of heaven and earth are offered in the name of heaven's children. The Hen-Gong ceremony was the time that the Day of All Things was instituted. He proclaimed at this time that from the following year the lunar calendar date of May 1 would be decided as the Day of All Things. (Seng-Hwa magazine, no. 29)
