From an article by Mat Gardner in the Anglican Church News:
As summer turns to autumn, Christians worldwide will unite in prayer and commit to the ministry of healing the earth during the Season of Creation, an annual initiative spearheaded by global Anglican, Roman Catholic, ecumenical, and interfaith organizations. The Season of Creation runs from Sept. 1—proclaimed as the World Day of Prayer for the Care of Creation by the Orthodox Church in 1989, and subsequently recognized by other denominations—through the Feast of St. Francis of Assisi on Oct. 4. During this period, Christians across denominations and national borders are encouraged to join together in prayer for creation and environmental stewardship.
