While environmental concerns may be lifted up in worship at any time, some days in the church calendar have taken on special significance:
- The Feast Day of St. Francis on October 4. Often called the “patron saint of ecology,” St. Francis’ love for the poor as well as for the whole creation makes him a fitting symbol of Christian commitment to environmental justice. The Catholic Climate Covenant: The St. Francis Pledge to Care for Creation and the Poor, an initiative of the Catholic Coaltion on Climate Change, offers liturgical resources (available in Spanish) and a Planning Guide to help individuals, families, parishes, schools, and other Catholic organizations celebrate the Feast of St. Francis.
- Rogation Days (in the spring), a traditional time for blessing fields, gardens, and orchards.
- Assumption Day (August 15), when the produce of the land may be blessed.
