Yalda Night (Shab-e Chelleh) is a Persian winter event that is commemorated on or around December 20 or 21 each year.
These days many Iranians are out making their purchases of fruits such as pomegranates, watermelons, and various dried nuts.
Today, Yalda celebrations have become a social occasion when friends and family gather to eat, drink and read poetry (especially Hafiz) until after midnight.
Each member of the family makes a wish and randomly opens Hafez's book of poems and recites the poem, which is believed to be an interpretation of the wish.
Fruits, particularly pomegranates and watermelons, and nuts are served in this night. The fruits signify the hope for having a fruitful spring and summer.
The red-colored fruits are believed to symbolize the crimson hues of dawn and glow of life, invoking the glory of Mithra. Pomegranates with angelica powder are also believed to protect individuals against the Devil.
Central Asian countries such as Afghanistan, Tajikistan, Uzbekistan, Turkmenistan and some Caucasian states like Azerbaijan and Armenia share the same tradition as well and celebrate Yalda Night annually at this time of the year.
Yalda Night was officially added to Iran's List of National Treasures during a special ceremony in 2008.
The annual winter ceremony manifests the traditional concept of light and good prevailing over darkness and evil in the ancient Iranian religion.
