The word yugapāda seems to indicate that Āryabhața divided the yuga into four equal quarters. There is no direct statement to this effect, but also there is no reference to the traditional method of dividing the yuga into four parts in the proportion of 4, 3, 2, and 1. Brahmagupta and later tradition ascribes to Āryabhața the division of the yuga into four equal parts. For the traditional division see Sūryasiddhānta (I, 18–20, 22–23) and Brahmagupta (I, 7–8). For discussion of this and the supposed divisions of Āryabhața see Fleet. Compare III, 10, which gives data for the calculation of the date of the composition of Āryabhața's treatise. It is clear that the fixed point was the beginning of Āryabhața's fourth yugapāda (the later Kaliyuga) at the time of the great Bharata battle in 3102

Compare Brahmagupta (I, 9)
