Iran is one of the oldest countries in the world. Usually, being a country with centuries of history behind it means having lots of celebrations, ceremonies, and customs being held annually. The celebration of Yalda Night is one of them.
Iranians have celebrated the longest night of the year for centuries, and on December 21 of each year, they have waited for the sun to come up again and celebrated the dawn of the first day of winter and welcomed the longer days, the presence of light and warmth for a minute more each day.
