The holiday of Zervan-Karan begins on January 4—5, when the Sun enters the 15th degree of Capricorn.
On the eve of this day — on January 4, when the Sun is in the 14th degree of Capricorn, nothing is celebrated. This is a day of emptiness and silence. And the more you manage to remain silent on this day, the better. At this time, from sunrise to sunset they fast and don’t even drink anything. They light 2 fires.
From January 5 to January 17, — is 12 days of celebration. Zervan — according to Zoroastrian concepts — is something absolutely unknowable by man, on the other hand, Zervan is turned to for protection from all distortions, from evil. Zoroastrians believe that time is of four types — past, present, future and eternal.
Zervan-Karana symbolizes the closed time in which people live due to the duality of their nature. Bodily, a person lives in a cyclic, closed time, that is, he is born and dies. His soul and Spirit are immortal, and abide in the eternal.
Sacred plants — pine and spruce — these days are the main decoration of the home. Also on the Zervan-Karan holiday, oil lamps are lit, torchlight processions, carnivals, and masquerades are held. They buy watches and wonder about the future.
