Heavenly Calendar

The Unification movement observes six principal Holy Days: God's Day, True Parents' Day, True Children's Day, the Day of All True Things, the Day of Victory of Love, and Foundation Day. Each of these days marks a specific providential milestone — not a cultural tradition or a seasonal festival, but a moment when a spiritual standard was established in human history for the first time. Observed according to the Heavenly Calendar — which follows the lunar cycle — their dates shift each year relative to the solar calendar.

God's Day was inaugurated by Rev. Moon on January 1, 1968, at 3 a.m. at the Unification Church headquarters in Cheongpadong, Seoul, Korea. It was the first day in history, Rev. Moon taught, when God could truly be honored in His own right — not as a distant ruler, but as a Parent whose children had finally returned to Him through a foundation of restored love. The ceremony has traditionally begun at midnight, with Rev. Moon offering a prayer and then speaking to members gathered from around the world. In 1994, the name was updated to True God's Day to reflect a deeper understanding of God's nature as the Heavenly Parent.

Foundation Day was proclaimed on January 13, 2013 (by the Heavenly Calendar), marking what the Unification movement regards as the formal inauguration of Cheon Il Guk: the Kingdom of Heaven on earth and in heaven. It is considered the most historically significant date in the entire restoration providence — the culmination of all the preparation, suffering, and indemnity conditions laid over thousands of years of human history.

The Day of Victory of Love was established on January 2, 1984, following the death of Rev. Moon's son Heung Jin Nim in a traffic accident on December 22, 1983. Rather than being observed as a day of mourning, Rev. Moon declared it a day of victory — teaching that his son's death, embraced with love and without resentment, had broken Satan's claim over human lineage in a way that could not otherwise have been achieved.

True Parents' Day was the first to be established — on April 1, 1960 (by the lunar calendar), shortly after Rev. Moon's Holy Wedding with Hak Ja Han on March 1, 1960. True Children's Day followed in October 1960. The Day of All True Things came next, in June 1963 — each day building on the one before, completing the four-position foundation step by step.

Ahn Shil Il — meaning "Day of Sabbath" or "Day of Rest" — is a weekly observance in the Unification movement marked in blue on the Heavenly Calendar. Ahn Shil Il is understood as a day of spiritual restoration — a time for families to gather, recite the Family Pledge, engage in Hoon Dok Hae, and rest from ordinary labor as a reflection of their alignment with God's creative rhythm.

The Heavenly Calendar is a lunar calendar used within the Unification movement to track the dates of holy days, Ahn Shil Il, and other providential observances. Most of the movement's key dates were originally established according to the lunar calendar, which means their corresponding Gregorian dates shift each year. By observing the Heavenly Calendar, members participate in the providential rhythm consciously — ordering their weeks around Ahn Shil Il and their year around the six holy days rather than around national or commercial holidays alone.
