Iranians are mostly Muslims and celebrate the New Year on the first day of their spring.
The time of Islamic festivals is calculated according to local sightings of various phases of the moon and the dates given below are approximations which are subject to change each year.
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.
