Iranians are mostly Muslims and celebrate the New Year on the first day of their spring.
Twelver Shi'i Islam is totally dominating the Iranian society, not only as creed, but also with its impact on the political system.
The Iranian wedding ceremony despite its local and regional variations, like many other rituals in the country goes back to the ancient Zoroastrian tradition. Though the concepts and theory of the marriage have changed drastically by Quran and Islamic traditions, the actual ceremonies have remained more or less the same.
