As noted by researchers and historians in their scholarly sources, the Sada festival is of great importance from the perspective of human biology and ecology as well. Sada is viewed as the result of biological observations, human adaptation to the environment, and an understanding of the natural life cycles. Festivals play an important role in regulating physiological, psychological, and social processes. It is precisely the Sada festival that is celebrated during a biologically sensitive period—the middle of winter—which indicates a deep understanding of this natural law by our ancestors. The time of its celebration falls in the second half of winter, that is, the period when all vegetation and plants, after prolonged adaptation to cold conditions, enter a state of physiological readiness for spring activation.
Since ancient times, the Sada festival has been a celebration of cooperation and unity among the ancient Aryan peoples, as well as a festival of fire. Most importantly, one of the most significant events in the history of humanity was the discovery of fire.
In one of his messages, the Leader of the Nation, President of the Republic of Tajikistan, His Excellency Emomali Rahmon, identified the farmer as the main factor in preserving the Sada festival up to the present day:
“The Sada festival, from the period of the emergence and development of agriculture, acquired socio-economic significance and became one of the means of promoting and encouraging agricultural and horticultural activities. For this reason, farmers honor this ancient ritual more than other segments of the population, and perhaps it is precisely the farmer who is the reason why Sada has survived to this day.”
It is likely that this historical status of the Sada festival has led to the fact that today, in all corners of Tajikistan, with the participation of responsible workers in the agricultural sector, as well as all farmers and dehkan households, its celebration has become a nationwide tradition.
