Unitarian Universalists honor and celebrate a wide range of holidays and occasions over the course of a year. Unlike other faith traditions that use a single lectionary (a collection of scripture readings appointed for a given day or occasion), the topics and themes for Unitarian Universalist worship services are usually chosen independently by worship leaders in congregations. These include unique UU traditions, like the Water Ceremony and Flower Ceremony, as well as holidays from other faith traditions, such as Christmas or Beltane.

The holiday celebrations in Unitarian Universalist congregations reflect the six Sources of our faith.

Many Unitarian Universalists and our congregations celebrate Christian holidays like Christmas, Jewish holidays like Passover, and Pagan Winter Solstice, among others. Our holiday services use the stories and traditions creatively, calling us to our deeper humanity and our commitment to the good.

In addition to religious holidays, we also honor secular holidays including Earth Day, Martin Luther King Jr. Day, Labor Day, Indigenous Peoples Day, and Thanksgiving.
