Nardoqan or Nardugan (Kazakh: Нартуған, [nɑrto̙wˈɣɑn], Turkish: Nardoğan, Azerbaijani: Narduqan) 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.

But associated with following words: And Turkic verb Doğmak (that means to born or to rise) merged and combined with this root.
