Christmas in Iran is known as the Little Feast. For the first 25 days of December, a great fast is observed, during which no meat, eggs, milk, or cheese is eaten.
With a long-standing and proud civilization, Persian culture is among the richest in the world.
There is a vastly extended network of rivers in Iran most of which seasonally are filled with water. Some permanent rivers run from the Alborz or the Zagros to the Caspian Sea, Persian Gulf and Oman Sea.
