Many of astronomers of ancient days had different versions of what time period constituted the yugas on the macroscopic scale of time.

The later time points in Kali yuga are calculated in our calendars and Panchangas. Based on the periodical natural observations such as the sunrise and sunset, new moon, full moon, and seasons, a working scale of time - consisting of day, fortnight, month and year - has been used from early times. Accurate prediction of the ending moment of tithis, sankramana (transit of sun across rasis), eclipses etc seem to have contributed in a big way to the growth of mathematics in India.     

The later time points in Kali yuga are calculated in our calendars and Panchangas. Based on the periodical natural observations such as the sunrise and sunset, new moon, full moon, and seasons, a working scale of time commonly reckoned as the present [[Kalamana (कालमानम्)]] - consisting of day, fortnight, month and year - has been used from early times. Accurate prediction of the ending moment of tithis, sankramana (transit of sun across rasis), nakshatra and rashi transits, eclipses which have been discussed in established astronomical texts show, in a big way, the growth of mathematics in India.
