The floor-plates, the pillars and the columns have the two geometrical shapes of Dacian sanctuaries: the rectangle and the circle. Using numerical analysis and testing some original algorithms was obtained an unitary system of interpretation, which can be applied to any Dacian monument.

First of all it has been shown that the basic element of the entire system is the day made of 24 hours, this unit being equivalent to a pillar. Than the analysis of the Dacian year was done; this one was made of 47 weeks: 8 weeks made of 8 days, one week of 7 days, 3 weeks of 8 days, one week of 6 days, and so on, according to the structure of the small circular sanctuary made of 8 groups with 8 pillars, one group of 7 pillars, 3 groups of 8 pillars, one group of 6 pillars separated by 13 plates.

From this point it was deduced that the year was divided in three trimesters made of 13, 21, 13 weeks, the longest one being the time between the appearance of the sap and the falling of the leaves.

The two weeks made of 7 and 6 days made the years fluctuate; inside a circle of 13 years there were 4 years of 364 days, 4 years of 365 days, 4 years of 366 days. Because of this mechanism it was possible ,each 13 years, a day to be added, resulting a surprising resemblance to the exact astronomical time.

The "Dacian" century" consisted of 104 years, and was marked by the 104 floor-plates of the circular sanctuary and by the 52 columns. The "millennium" had 520 years, and it was represented by the big rectangular sanctuary made of 40 columns, each meaning a 13 years cycle (40x13 = 520).

The counting was behind the real astronomical time but because of the way in which the small sanctuary was built it was possible the determination of the fluctuant duration of the years; after the correction was made the exactitude of the resulted medium year was quite amassing.

These sanctuaries remained in people's memory, for instance at the folk dance "Călusari" take part 13 dancers, the magic spell and the good wishes include notions such as a 13 years cycle and a life of 104 years old, etc.

The sanctuaries prove once again that in the Carpathian Mountains existed one of the most powerful roots of the humanity, these monuments certifying the Romanian continuity on this territory.
