Adherents of Slavic Native Faith often adopt elements from recorded folk culture, giving new meaning and purpose to Christianised or non-Pagan contents. Some Rodnover groups have appropriated or reappropriated Christian festivals. The same Kupala Night is a reappropriation, being the day of the year when Christian churches set the Nativity of Saint John the Baptist. The calendar of some Sylenkoite organisations includes holidays that have been de-Christianised, such as a "Christmas of Dazhboh's Light" and an "Easter of the Eternal Resurrection".
