Most private Waldorf schools celebrate holidays and festivals that are an anthroposophic or simply school-specific interpretation of the local culture's holidays and festivals. Festivals can be secular in character, combine elements of several religious traditions, as is frequently the case in multi-cultural settings, or represent the dominant local tradition, as is generally the case in parts of Europe (Christian festivals), Egypt (Islamic festivals), Israel (Jewish festivals, but see Intercultural links in socially polarized communities), and India and Thailand (Buddhist festivals).
In North America and Europe most private Waldorf schools celebrate several Christian-based holidays and festivals, often with an Anthroposophic interpretation, including Martinmas and the four seasonal festival]of Michaelmas (fall), Christmas (winter), Easter (spring), and St. John's (summer). Although a majority of the schools' celebrations in North America and Europe are Christian-based, most North American private and European Waldorf schools also celebrate celebrations and festivals drawn from other traditions.
In the kindergarten and earliest elementary schools years, most Waldorf schools also celebrate something known as the Advent Spiral. This festival, celebrated in the weeks prior to the winter solstice, is also called a Advent Garden, Winter Garden, or Spiral of Light. In this ceremonial celebration, children enter, one at a time, into a large spiral of lit candles. As the parents sing the child a song or music is played, each child lights a candle and as the ceremony progresses, the spiral becomes brighter and brighter. The entire ceremony is conducted without any narration or interpretation, but the spiral and the lighting of the candles symbolizes many things in Anthroposophy: the turning and renewal of the year, the path of incarnation on earth, etc.
