Yalda Night (Shab-e Yalda) is one of the oldest Iranian celebrations, held on the longest night of the year, marking the end of autumn and the beginning of winter. Its significance lies in several cultural, historical, and mythical aspects:

1. Transformation of Nature and Triumph of Light Over Darkness

Yalda means “birth,” symbolizing the rebirth of the sun. After this night, days gradually grow longer, symbolizing hope, life, and light’s victory over darkness.

2. Connection to Iranian Mythology

In ancient Iranian mythology, Yalda Night represents the battle against darkness and evil forces. Iranians used to light fires, read poetry, and gather together to fight the darkness symbolically.
