Yaldā Night is an ancient festival in Homeland, Afghanistan, Azerbaijan, Uzbekistan, Tajikistan, Turkmenistan that is celebrated on the winter solstice. This corresponds to the night of December 20/21 (±1) in the Gregorian calendar, and to the night between the last day of the ninth month (Azar) and the first day of the tenth month (Dey) of the Iranian solar calendar.The longest and darkest night of the year is a time when friends and family gather together to eat, drink and read poetry (especially Hafez) and Shahnameh until well after midnight.
Fruits and nuts are eaten and pomegranates and watermelons are particularly significant. The red colour in these fruits symbolizes the crimson hues of dawn and the glow of life. The poems of Divan-e Hafez, which can be found in the bookcases of most Iranian families, are read or recited on various occasions such as this festival and Nowruz. Shab-e Yalda was officially added to UNESCO Intangible Cultural Heritage Lists in December 2022.
