Nardoqan or Nardugan (, , , , ) was a Turkic holiday concept in Tengriism. Nowadays, it is most commonly used to refer to the winter solstice in many Central Asian and Siberian languages. The holiday is akin, both in terms of timing and also the concept (the birth of the sun), to Yalda Night. Given the historicity of Turko-Persian (religious, literary, and cultural) ties, and the symbolism of pomegranate fruit among Iranians during Yalda, the two festivities manifestly share origins. It is also used as an equivalent name for the Christian holiday Christmas.
