We give below the system as it is indicated in the Vishnu Purana 1.3.ġ निमेष = Time taken to pronounce a letter with one मात्रा, time taken for twinkling of eyeġ2 human months = 1 human year = 1 Deva/पितृ dayģ0 days of the देव/पितृ = 1 month of the देव/पितृ In ancient India, a system of time measurement starting with the time taken for twinkling of an eye and going up to the age of the Creator Brahma, based on the solar year, which corresponds to one human year as we observe now, was in vogue, right from the time of the Vedas, thereby esablishing its antiquity.Įvidence for the fact that our forbears had their own system of time measurement, is available in the references to this in the Vedas as well as the Puranas. Many astronomical works have been written in India based on the solar system, such as the Surya Siddhanta etc.

In others, they follow a system based on the time taken by the earth to revolve round the sun once. In some countries, they follow a system based on the revolution of the moon round the earth. All systems of time measurement are based on the time of revolution or rotation of various celestial bodies including the moon and the sun. This involves a time scale based on some system of measurement.

we do certain specific activties during specific times. We do so many activities daily during our life-time. While browsing the web I saw this aeticle on ' Time measurement in ancient India' I thought that this will be interesting to many,hence,posting it.
